Shell - For most people, the shell is the most obvious feature of the traditional spark plug. In these instances, a colder plug may be needed. Understanding Spark Plug Heat Ranges Understanding Autolite Spark Plug Numbering System Torque Specifications Heat Range Facts Half Thread/Full Thread Explanation Autolite Copper Core Spark Plug Attributes Understanding VIN Codes Autolite Double Platinum Spark Plug Attributes Original Equipment Platinum Spark Plug Applications E3 Spark Plugs Power Sports E336 E3 Motorcycle Spark Plug Overall Score: 9.1 7. When purchasing new spark plugs be sure to ask if the gap has been set or if it needs to be adjusted. 3021 W16EPR-U 37334 11IR5Y 3036 W16P-U 37394 15IR5Y 3057 W20ESR-U 37344 11IR6 3076 W20SR-U 37404 15IR6 CAUSES OF OVERHEATING: Spark plug heat range too hot; Insufficient torque and/or no gasket; Insufficient engine cooling or lubrication; Excessively lean air/fuel mixture; Over-advanced ignition timing. MSD Cross Reference with DENSO Stock Number to Plug Type. However, the less amount of material near the gap the more rapid growth of flame kernels. Worse yet, despite today's comprehensive engine management, the data is only as good as the tools used to read the fuel mixture: the oxygen sensor. No (42) Resistor. Tech resources for teachers, a la Bernajean Porter, 4th Grade ELA Common Core Writing - Range of Writing. "In testing, we have seen small engineslike those in motorcyclespick up as much as 12 percent in power and 13 percent in fuel savings. A switch in heat range of the spark plug will change the temperature of the spark plug tip by 70-120 degrees. Forced-induction and nitrous applications produce extremely high cylinder pressure and heat that create extremely fast burn rates. Therefore, this type of spark plug is generally used for high speed, high output engines. Even so, E3 is confident that there is still room for improvement in direct-injected engines. Old plugs can cause a loss of nearly 2-3 miles per gallon! For your benefit, we didn't exactly take it easy on him, either. 0000008568 00000 n We also like using those cheap handheld microscopes for shallower plugs. Looking at the ground strap and the tip of the porcelain insulator, you can quickly see the results of knock or timing adjustments before having to dive further into the plug for fuel. This prevents the hot lock groove from failing during installation or removal. However, for modified engines, youll need to select a spark plug based on the performance you want to achieve with your engine. Choose your next Champion from the range of plugs that live up to the legacy of this iconic brand. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. ACDelco 41-993 professional iridium spark plug. Reducing this variation can only improve engine output, and E3 says that its spark plugs can effectively reduce this variation in cycle-to-cycle cylinder pressure. Because they transfer heat faster, cold spark plugs can get dirty and become fouled sooner because they dont get hot enough to burn off carbon deposits. Plugs are still the honest witnesses of what's going on in the combustion chamber, and as Don Ward, E3 Spark Plugs' lead engineer, puts it, "It's the only thing that's in the combustion chamber that you can see; you can pull it right out and tell where it's rich or lean, or when it doesn't have enoughor too muchtiming." Try to isolate it to one cylinder then check that plug first. Other than getting the heat range correct, no one really thinks twice about spark plugs until an engine starts misfiring. As such, there are several ways in which the core components of a plug can be designed to improve performance. All dual precious metal plugs are designed to provide maximum longevity.. They are 3/16" longer than the stock NGK spark plugs therefor they will stick 3/16" further into the combustion chamber. The spark plug is heated during combustion and must dissipate that heat to the cylinder head at a certain rate to avoid overheating the ceramic firing end. Since each application requires a different heat range of spark plug, a typical street-style spark plug usually won't cut it. On the flip side, a modern EFI engine like the LS3 small-block offers extremely precise fuel delivery, an 11:1 compression ratio, and highly efficient aluminum cylinder heads and combustion chambers. A spark plug's heat range is the degree to which it disperses heat. The length of the insulator and the metal conductor core help determine a plug's heat range. 0000004022 00000 n Considering the lackadaisical approach most hot rodders take toward spark plug selection, what if someone came along and said you could increase horsepower and torque by 3 to 6 percent by simply swapping out the spark plugs? That's why we had a chat with Steve Joiner of E3 Spark Plugs. This results is less fuel being converted into energy, thus lowering combustion pressures," Steve explains. 4*`w aw6X. hb```b``-d`c`8 @1v 3 |>*d00dlPfi7S'0 lL-q;"R8;tJIPPjg0kIk\0I% G8E2 When the engine's various sensors detect the improved burn efficiency of E3 spark plugs, the ECU will begin to make adjustments to maximize efficiency," Steve explains. The purpose of an ignition coil is to multiply voltage between the battery and the spark plug, thus increasing spark energy to ensure complete combustion of the air/fuel mixture. "The improvements that E3 spark plugs provide tend to be more substantial and noticeable on older carbureted applications than newer EFI engines," says Steve. A spark plugs heat range is the degree to which it disperses heat. If it's too cold, it can result in fouling and misfires. That is also why you need to use a heat range/crossover interchange chart to compare plugs. Typical heat ranges for passenger car engines are usually . The traditional multiple side electrode and J-gap plug designs offer durability but shield part of the flame face as the fuel mixture burns in the engine's combustion chamber. This is usually the most misunderstood factor of reading plugs, because the fire ring is deep inside the plug and almost impossible to spot with the naked eye. The less often you have to do it the better. Eventually, it's cooled by the radiator. Spark Plugs. Many enthusiasts are surprised to learn that over hundreds of combustion cycles, not all combustion events produce the same amount of cylinder pressure. Use the proper tools to install your spark plugs, a 5/8" or 13/16" spark plug socket. Too cold and the spark plug will cold foul resulting in an engine misfire. And with E85, you want it to be a little further in the bend [but not to the weld].". The early plugs relied on magneto-based ignition wires to provide the electrical flow that a plug requires to do its job. 0000031888 00000 n "The 02 sensor will eventually lead foul and lead you astray, telling you the engine is leaner as it goes away, so you'll keep putting fuel in the motor. Consequently, in addition to optimizing combustion efficiency, E3 spark plugs boast multiple design features intended to increase durability as well. Spark plug charts are sorted by thread size, thread reach, hex size. If the heat range is too cold, the spark plug will be unable to properly self-clean by burning off carbon deposits. Adding a more sophisticated ignition system will not be negatively impacted by the E3 plug," says Steve. "A spark plug has two major functions for an internal combustion engine: It transfers heat from the cylinder to the head and ignites the air/fuel mixture," says Steve. The plug might be cracked and should be thrown away. CROSS REFERENCE GUIDE At the end of the spark event, a small flame kernel remains as raw gases continue to burn. Heat Range: 10. That's unburnt fuel," Don says. E3.42 is a 14mm, 0.460 reach plug with a taper seat. If you are running the Wordpress software, you will need the Embed Iframe plugin. What we do know is the U.S. Patent office began issuing patents to protect a variety of ignition products in the late 1800s. For most vehicles, the manufacturer-recommended spark plug and heat range is the best option. Boost, nitrous, and race fuel throw all kinds of variables into the overall combustion equation. Image Racing Spark Plugs 14mm Spark Plugs (cont.) 0000041618 00000 n In broad terms, spark plugs are often referred to as the term hot spark plug or cold spark plug. 0000434858 00000 n An important factor for a spark plug is the temperature that the tip is designed to withstand, called the heat range. The open architecture of the ground electrode also facilitates a faster flame kernel for a more complete burn of the fuel. Converting more fuel into energy equals better performance and fuel efficiency. Give your binder more style with rounded tabs by upgrading your account. Introduction. 5 (9) 4 (6) 16 (5) 20 (5) 2 (2) 8 (2) 12 (1) 14 (1) 9 (1) Get Results; Shorty Spark Plug. On the other hand, high heat range plugs have short insulator legs and the surface area affected by the flame and the gas pocket capacity are small. Likewise, older carbureted engines often have lower compression ratios, iron cylinder heads, and less efficient combustion chamber designs. You can use our onsite media player to check out the latest E3 Racing & Team Lucas Oil news posted in the E3 Video Center. Our spark plugs have been improving engine performance since 1907. "The shell includes the ground electrode, while the insulator consists of the center wire, resistor material, and terminal connector for the ignition leads. Don mentioned that when tuning an engine on the bleeding edge, like in a highly competitive drag-racing class, one or two specs are OK, but in a street motor, this is your first warning to stop and back off a few degrees. At first I really didn't notice a lot, but for whatever reason I seem to be getting another 60 to 75 miles on a fill up, and at the price of gas it really helps! Spark Plug Heat Range differences. When you increase Compression Ratio or use boost, chamber temperature increases. Autolite AP5325-4PK Fuel Efficiency Platinum Spark Plugs, 4-Pack Overall Score: 9.0 10. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. 0000006044 00000 n I saw a show on hotrod tv, they did a feature on your E3 plugs. The shell is a ceramic outer casing that is fitted into the threaded metal housing at the end of the plug where the ground electrode is found. "The core components of a spark plug are the plug shell and the insulator," Steve explains. Maybe it's time you replaced that 2-4 year old spark plug and upgraded to a premium plug for easier and quicker starts! Low heat range plugs have long insulator leg sections and the surface area affected by the flame and the gas pocket capacity are large. Nice to see a product that does what they say will do as a lot of products come and go -- your E3s went beyond what I ever expected. The purpose of an ignition coil is to multiply voltage between the battery and the spark plug, thus increasing spark energy to ensure complete combustion of the air/fuel mixture. 0000002710 00000 n But on the street, for driveability, you would want a power-tiptype spark plug. So [regarding] the heat range of the plug, you have to keep the plug hot enough to keep the tip clean, but cool enough that it doesn't cause detonation. E3 says that the . For instances, a turbo engine boosted to 20 psi may only require 18 degrees of ignition advance on C16 race fuel. These days, you're probably hearing about heat range when people are talking about bolt-on boost projects, but any time you increase cylinder pressure (through compression or boost), you need a colder plug, and it's a measure of how much heat the insulator can absorb to maintain proper plug temperatures and prevent it from overheating to the point where pre-ignition occurs. E3 had independent labs conduct tests on a variety of plug designs to determine the influence of the ground electrode on flame kernel formation, cycle-to-cycle variation and overall performance. You don't want to be the guy/gal stuck out on the water because of old plugs! While the primary function of the spark plugs is providing the spark to ignite the air/fuel combination and start the engine, an equally important function of the engines spark plugs is to remove heat away from the combustion chamber. If you see any melting of any kind, that's a sign of pre-ignition. If any of these components are damaged be sure to replace them or they may cause problems for your new plugs. Unlike a standard J-wire designwhich has a ground electrode that covers the center electrode, thereby impeding flame front growth into the combustion chamberthe E3 design exposes the spark more directly to the air/fuel mixture in the combustion chamber. In other words, our DiamondFire plug was "Born to Burn". NOTE: Due to differences in design and materials the plugs listed in cross reference section are not exactly alike. Most plugs have a specific torque requirement to ensure a tight fit without damaging the female threads in the engine. Every plug in the Laser Series was designed for an OEM application. 0000436378 00000 n It's summer timefinally! It fits domestic applications in the 80's to early 90's.

This process involves making a pull (on a dyno or a pass), and shutting down the engine ASAP so the reading isn't tainted by idle time. After a change is made, a new set of plugs are installed (you cannot re-read used plugs accurately), and you repeat your test run. Part# NGK STK # NGK # Comp. A fouled spark plug can lead to misfires and engine stalling. 0000002170 00000 n The listed heat range represents the plug's ability to dissipate heat. Please note that the numbers dont indicate degrees; theyre product codes to give an indication of the heat range. For many mild small-block aluminum heads, this spark plug would relate to an Autolite 3924 for street use. The least intrusive is using a doctor's otoscope, that thing the doctor shoves into your ear drum every year. Generally, in racing, you want them to run as clean as possible. Spark Plugs help remove heat from the combustion chamber. "With alcohol, you only want it to turn into the bend. 0000006268 00000 n Take a look at the chart for the range of Champion offerings. Oh no, you are at your free 5 binder limit! REASONS FOR CARBON FOULING: Continuous low speed driving/short trips; Spark plug heat range too cold; Air/fuel mixture too rich; Reduced compression and oil usage due to worn piston rings; Ignition system worn out. Once the voltage created by a magneto or ignition coil exceeds the dielectric strength of the gases in the motor's combustion chamber, an explosion occurs and the piston is send downward completing a cycle. Thread - 14mm. The difference between one heat range to the next represents the ability to remove 70 - 100C. So if you're racing that engine, then you'd get a regular-tip plug, which. "On modern computer-controlled engines, the system is trying to achieve the lowest engine rpm while maintaining a steady, complete combustion event. . For most cars and trucks, the rubber boot at the end of each ignition wire can be firmly pushed over the terminal's barrel-like tip. Stock No. E3 Spark Plugs >> E3 Spark Plug Catalog. The unique ground electrode and full-size center electrode also provides optimal performance for a guaranteed five years or 100,000 miles. Fortunately, E3's R&D department is working overtime to introduce its unique technology into the race market as well. E3 says that the diamond-shaped straps on its plugs use the available voltage in the ignition system more efficiently. Since the central electrode and insulator run the length of the plug, ribs improve insulation and prevent electrical energy from leaking out before it reaches the ground electrode and creates a spark. and material, plugs produced by various manufacturers do not have exactly the same heat range.
