The relationship between the spark plug temperature and vehicle speed and heat range is expressed with a graph like that in the figure. All Rights Reserved. Set of 4 Spark Plugs. In times like this, it's better to choose a plug with a higher heat range. of the iridium down to 0.4mm. Low heat range plugs have long insulator leg sections and the surface area affected by the flame and the gas pocket capacity are large. It's not really a fair comparison to Denso IK22 which is a fine wire iridium. GST # 000580009984. $31.16. The better question would be NGK BKR7EIX (stock# 2667) vs. Denso IK22 (This way you are comparing Apples to Apples). Starting with part # IK20 (heat range 20), a colder plug would be # IK22, a hotter plug would be # IK16. Moreover, the special iridium alloy used was developed by DENSO with the following patented processes (for all types): Japan (2877035, 2921524, 3000955), U.K. (2302367), U.S.A.

The relationship between the spark plug temperature and vehicle speed and Tel : 05-5061268 (The terminal nuts on the IWM and IK-G types are solid parts and cannot be removed. Features: 0.4mm Iridium Tipped Laser Welded Fine Wire Center Electrode; Tapered Cut U-Groove Ground Electrode Increases Ignitability and Decreases Quenching Add to cart. 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. ), Highly Corrosion Resistant, Burnished Nickel Plating, The plug housing is plated with burnished nickel, the same as plugs used for racing. Sold Individually Denso IK22 Iridium Power Spark Plug For some applications, iridium can be six times harder and eight times stronger than even platinum, and it can withstand temperatures of greater than 4,000 degrees Fahrenheit. One Of The Biggest Auto Performance Accessories Tyre Shop In Ipoh. With a 0.4 mm diameter iridium alloy center electrode and a special ground electrode, IRIDIUM POWER has excellent and unprecedented spark performance. See cross reference chart for Denso IK22 and more than 80.000 other spark plugs. stock are equal to IK22, im running IK27's in mine. When the center electrode reaches 950°C or higher, pre-ignition (early ignition) occurs, meaning that the electrode serves as a heat source and ignition occurs without a spark. Spark Plugs > Denso Iridium Power Plug One Step Colder IK22 - Subaru WRX 2002-2005; Denso Iridium Power Plug One Step Colder IK22 Subaru WRX 2002-2005 +2. Low heat range spark plugs have center electrode temperatures that rise easily and even at low-speed, they easily reach the self-cleaning temperature, so carbon is not deposited easily on the insulator section. From United Kingdom. I'm BPU + and wondering if the Denso IK22's are the appropriate plug for my mods on my 1997 Supra turbo. Using the same approach, iridium is alloyed with rhodium. Therefore, this type of spark plug is generally used for high speed, high output engines. These Denso (5340) ITV22 plugs are the same ones that a tune shop recommends for almost twice the price. 111,JALAN KUALA KANGSAR, - Denso lists the following heat range equivalence with NGK: (NGK=Denso) 5=16, 6=20, 7=22, 8=24, 9=27. Denso (2) Denso. AUD Inc GST. 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. Ok, the factory heat range for Denso plugs is designated by the number 16. 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. (Low-heat range types excluded). I honestly wasn't expecting this: ... IK22's are two heat ranges colder than stock. This results in a steady combustion in a variety of driving conditions, and better starting and acceleration for the engine. ... but if he is boosting at all then he need to go down 2 heat ranges. I always run 93 octane. Heat Range 22; Torque Specs Cast Iron: 26-30 lb. 30010,IPOH PERAK.Malaysia. Regapping the denso iridiums is not recommended and is kinda a pita. SKU: IK22 Categories: Ignition System, Performance Parts Tag: Denso. (For all plug types). The heat that the electrode section of the spark plug receives due to combustion is dispersed through the path in the figure. CHAMPION(U.S.A.) Narrow. All rights reserved. 8/1/17 update: check upon receipt for loose terminals, i waited to long and when i did,1 out of 4 was loose and my date of return had expired. This is largely determined by the temperature of the gas inside the combustion chamber and the spark plug design. Shop with confidence. DENSO spark plugs use iridium alloy for their center electrode. legal Heads NGK B9ES Ch14YC or AL3924 IW24 gas, IW27 alchohol IK16 DART Get more power with an optimal combustion cycle. It's not detonating. Depending on the composition of the alloy, the matrix material’s properties can be maximized. Brand New Denso Iridium Spark Plugs. Brand New. Autolite has 2544, 2545 and 2546 available. In order to improve ignitability, the center electrode protrudes more than with conventional type plugs This improves both acceleration response time and performance. Part # 5310-IK22-GRP $ 31.16. 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). Bereits ab 6,82 € Große Shopvielfalt Testberichte & Meinungen | Jetzt Denso IK22 günstig kaufen bei idealo.de 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). AUD Inc GST. Please use our DENSO Spark Plug Lookup or contact us to find the right spark plug for your car. That is why it is necessary to select spark plugs with the appropriate heat range for the engine characteristics, running conditions, etc. Denso; Shop By. 10 product ratings - Denso IK22 Spark Plug 5310 Iridium Power Replace 067700-8430 BKR7EIX. Continue Shopping. I tried e-mailing the Denso distributor in So-Cal but have not heard peep from them. Add to Wishlist; Product Name. 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. CAUTION *Use IXU22I and VXU22I with 3SZ-VE engine. The process used to mount the iridium tip is a highly reliable “All-around Laser Welding” process that is able to withstand all kinds of driving conditions. 2) They come pregapped around ~ .028 if i recall correctly, and the level of boost you're running that will be perfect.
