That is why it is necessary to select spark plugs with the appropriate heat range for the engine characteristics, running conditions, etc. Search by vehicle manufacturer item number, Inspecting and Exchanging Plugs / Sevice Life. e-Mail : wctslks@hotmail.com Regapping the denso iridiums is not recommended and is kinda a pita. These were not pure metals, but alloys containing other metals. GST # 000580009984. 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). All Rights Reserved. Find great deals on eBay for denso iridium ik22. The relationship between the spark plug temperature and vehicle speed and Add to Wishlist; Denso Iridium IK24 Spark Plug (Heat Range 8) $23.00. Add to Wishlist; Product Name. Let IPG Parts be your one stop shop for all your Denso needs !! See cross reference chart for Denso IK22 and more than 80.000 other spark plugs. - Denso lists the following heat range equivalence with NGK: (NGK=Denso) 5=16, 6=20, 7=22, 8=24, 9=27. Once you have decided on a number, test to see if it exists by typing it into the search box. From United Kingdom. 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. Add to cart. AUD Inc GST. Increased response and acceleration performance. The last digit in an Autolite part number represents the heat range within a plug family. The better question would be NGK BKR7EIX (stock# 2667) vs. Denso IK22 (This way you are comparing Apples to Apples). To improve ignitability, the contact area between the electrode and the flame kernel must be reduced. I'm BPU + and wondering if the Denso IK22's are the appropriate plug for my mods on my 1997 Supra turbo. ), Highly Corrosion Resistant, Burnished Nickel Plating, The plug housing is plated with burnished nickel, the same as plugs used for racing. $20.00 and above (2) Brand. This cooling affect is greater with larger electrodes, sometimes causing the ignition to stop short of the stage in Figure 4. Shop with confidence. This enables the reduction of voltage necessary to cause the spark, and greatly improves ignitability. 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. For example, take the 254x plug series. ft. Aluminum: 15-22 lb. The heat that the electrode section of the spark plug receives due to combustion is dispersed through the path in the figure. In times like this, it's better to choose a plug with a higher heat range. stock are equal to IK22, im running IK27's in mine. iridium center electrode is, The good ignitability from the fine electrode (0.4mm) of. When the center electrode temperature is 500°C or lower, free carbon generated when the fuel does not combust completely is deposited on the surface of the insulator. 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.

Product Description 111,JALAN KUALA KANGSAR, Notice: id was called incorrectly. These Denso (5340) ITV22 plugs are the same ones that a tune shop recommends for almost twice the price. 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. In order to improve ignitability, the center electrode protrudes more than with conventional type plugs This improves both acceleration response time and performance. 2544 … Add to Cart. DENSO spark plugs use iridium alloy for their center electrode. Buy Denso (5345) IKH22 Iridium Power Spark Plug, (Pack of 1): Spark Plugs - Amazon.com FREE DELIVERY possible on eligible purchases On the other hand, high heat range spark plugs have center electrode temperatures that do not rise easily, so they are unlikely to reach the pre-ignition temperature even at high speed. 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. (The terminal nuts on the IWM and IK-G types are solid parts and cannot be removed.

Tel : 05-5061268 When the air temperature is high, as in the summer, the inlet air temperature becomes higher, increasing the load on the engine. Continue Shopping. 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. Using 0.4mm dia. This shape enables lower voltage needed to cause the spark and results in excellent ignitability without increasing the size of the spark gap. Find great deals on eBay for denso ik22 and denso ik22 5310. For example, IK20 has a heat range of 20. Therefore, the insulation between the insulator and the housing falls, electricity leaks occurs, the spark across the gap is incomplete, causes ignition failures. Is the insulator, heat range and other specifications appropriate? This iridium/rhodium technology was recognized by the Patent Offices of Japan and the UK, and in January 1999, a patent was granted in each respective country. The 0.4mm center electrode increases output under various driving conditions. 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. Denso plugs get colder the higher the number, hotter the lower the number. It's not detonating. It's not really a fair comparison to Denso IK22 which is a fine wire iridium. Denso IK22 spark plugs after 30K miles of Supercharged driving. IK22. 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). 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. Heat Range; SPARK PLUG Installation; Identifying Denso Plugs; Cross Reference; ... Search for DENSO spark plugs by spark plug manufacturer. The tip of the ground electrode is cut to a fine taper to reduce the adverse effects of quenching, which greatly improves fuel ignitability.

Therefore, this type of spark plug is generally used for high speed, high output engines. FYI: They do fit in my 2015 mustang ecoboost even though the Amazon and the Denso websites claim they do not fit. (Low-heat range types excluded). 307 replacement spark plugs for Denso IK22. It produces stable, high … To increase ignitability, the important point is to let the flame kernel caused by the spark to grow to a large size. 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. The degree to which a spark plug disperses the heat it receives is called its "heat range". Features: 0.4mm Iridium Tipped Laser Welded Fine Wire Center Electrode; Tapered Cut U-Groove Ground Electrode Increases Ignitability and Decreases Quenching The Secret behind DENSO’s Iridium Patent! DENSO has been setting the standard for spark plug technology since 1959. Using a new iridium alloy with a very high melting point, the tip of the electrode can be made very fine. Recommended Plugs in this Heat Range: The finer the electrode, the more concentrated the electrical potential and the stronger the electrical field strength becomes, leading to a lower required voltage. Ok, the factory heat range for Denso plugs is designated by the number 16. The relationship between the spark plug temperature and vehicle speed and heat range is expressed with a graph like that in the figure. Larger the number, the colder the plug (for Denso...and most spark plug brands) Follow this link to see a nice chart of spark plug heat range designations: DENSO SPARK … Heat Range 22; Torque Specs Cast Iron: 26-30 lb.
