I honestly wasn't expecting this: ... IK22's are two heat ranges colder than stock. DENSO spark plugs use iridium alloy for their center electrode. Using a new iridium alloy with a very high melting point, the tip of the electrode can be made very fine. C $16.14. Therefore, the insulation between the insulator and the housing falls, electricity leaks occurs, the spark across the gap is incomplete, causes ignition failures. Read 3 Reviews | 5 Q&As. Denso IK22 (Iridium Version of the same plug above) COLDER - NGK #8 (Two Steps Colder) - Cars with bigger turbos will benefit from these, whereas a regularly chipped car may foul these. The degree to which a spark plug disperses the heat it receives is called its "heat range". These were not pure metals, but alloys containing other metals. This temperature of 500°C is called the self-cleaning temperature because above this temperature the carbon is naturally burnt away completely by combustion. ... but if he is boosting at all then he need to go down 2 heat ranges. The heat range will change with the seasons.

Also, since the heat release path from the insulator leg section to the housing is long, heat dispersal is low and the temperature of the center electrode rises easily. Denso plugs get colder the higher the number, hotter the lower the number. All Rights Reserved. Both of these plugs are very similar but I think the NGK is around $2-3 cheaper per plug and should outlast the Denso iridium a good amount. For example, take the 254x plug series. Copyright ©2018 DENSO CORPORATION. Also since the heat release path from the insulator leg section to the housing is short, heat dispersal is high and the temperature of the center electrode does not rise easily. The last digit in an Autolite part number represents the heat range within a plug family. Image is generic and may not represent actual product. Low heat range plugs have long insulator leg sections and the surface area affected by the flame and the gas pocket capacity are large. See cross reference chart for Denso IK22 and more than 80.000 other spark plugs. Regapping the denso iridiums is not recommended and is kinda a pita. The heat that the electrode section of the spark plug receives due to combustion is dispersed through the path in the figure. Product Description Product properties should not be accessed directly. This is largely determined by the temperature of the gas inside the combustion chamber and the spark plug design. CAUTION *Use IXU22I and VXU22I with 3SZ-VE engine. IK22. In order to improve ignitability, the center electrode protrudes more than with conventional type plugs This improves both acceleration response time and performance. of the iridium down to 0.4mm.

Let IPG Parts be your one stop shop for all your Denso needs !! When the air temperature is high, as in the summer, the inlet air temperature becomes higher, increasing the load on the engine. Add to Wishlist; Denso Iridium IK24 Spark Plug (Heat Range 8) $23.00. Also, because of the streamlined, taper-cut shape, the fuel-air mixture spreads more evenly in the gap, resulting in steady, reliable igniting of combustion. If you're looking for a miniscule performance gain and don't mind a shorter life span, then you'd go with the Denso IK series (in connection w/heat range consideration). Therefore, output falls and this can reach the level of electrode wear and insulator damage. One Of The Biggest Auto Performance Accessories Tyre Shop In Ipoh. Denso (2) Denso. It produces stable, high … Depending on the composition of the alloy, the matrix material’s properties can be maximized. For example, IK20 has a heat range of 20.

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. Starting with part # IK20 (heat range 20), a colder plug would be # IK22, a hotter plug would be # IK16. ft. Aluminum: 15-22 lb. Autolite's numbering system does not have a standardized heat range identifier. FYI: They do fit in my 2015 mustang ecoboost even though the Amazon and the Denso websites claim they do not fit. Unlike a typical platinum plug that has a 1.1mm diameter center electrode, DENSO Iridium Power plugs have the world’s smallest center electrode, measuring 0.4mm in diameter. This means that the voltage requirements are decreased while firing performance is greatly improved. Ok, the factory heat range for Denso plugs is designated by the number 16. AUD Inc GST. 2) They come pregapped around ~ .028 if i recall correctly, and the level of boost you're running that will be perfect. $20.00 and above (2) Brand. The tip of the ground electrode is cut to a fine taper to reduce the adverse effects of quenching, which greatly improves fuel ignitability. Shop with confidence. Add to Cart. There are restrictions on the temperatures at which spark plugs can be used: the lower limit is the self-cleaning temperature and the upper limit is the pre-ignition temperature.A spark plug only functions completely when its center electrode temperature is between these temperatures of about 500°C and 950°C. I always run 93 octane. DENSO Iridium Power Spark Plugs harnesses the power of Iridium, to reduce the surface area of the center electrode – the critical component of a spark plug. Because of its extremely narrow diameter of just 0.4 mm, engine output and acceleration response are greatly improved. Therefore, this type of spark plug is generally used for high speed, high output engines. Spark plugs with a high degree of heat dispersal are called high heat range (cold type) and those with a low degree of heat dispersal are called low heat range (hot type). The relationship between the spark plug temperature and vehicle speed and heat range is expressed with a graph like that in the figure. Denso Plug Part # I want to source Denso Iridium plugs here in Sydney, but am a little unsure of the part number (as they are not a common brand).
