Is the insulator, heat range and other specifications appropriate? 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. In order to improve ignitability, the center electrode protrudes more than with conventional type plugs This improves both acceleration response time and performance. These Denso (5340) ITV22 plugs are the same ones that a tune shop recommends for almost twice the price. Selecting for heat Based on data taken under the harsh conditions at races and rallies, TRD spark plugs exhibit powerful, stable, and consistent results even under high-load, high-speed driving conditions, so that your engine can accelerate smoothly. This temperature of 500°C is called the self-cleaning temperature because above this temperature the carbon is naturally burnt away completely by combustion. See cross reference chart for Denso IK22 and more than 80.000 other spark plugs. 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). 10 product ratings - Denso Iridium IK22 Spark Plugs Set of 4 (5310) Heat Range 7 Equivalent. 307 replacement spark plugs for Denso IK22.

It produces stable, high … Therefore, this type of spark plug is generally used for high speed, high output engines. 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. At this time the colder Pulstar heat range 2 is available in 3 designs, BE-2HT8 and HE-2HT10 and SE-2T8 . Ok, the factory heat range for Denso plugs is designated by the number 16. The rhodium layer covers the iridium, improving the properties of the iridium. Once you have decided on a number, test to see if it exists by typing it into the search box. 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. 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. 10 product ratings - Denso IK22 Spark Plug 5310 Iridium Power Replace 067700-8430 BKR7EIX.

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). CAUTION *Use IXU22I and VXU22I with 3SZ-VE engine. This means that the voltage requirements are decreased while firing performance is greatly improved. Notice: id was called incorrectly. 5.0 out of 5 stars. 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; Shop By. That is why it is necessary to select spark plugs with the appropriate heat range for the engine characteristics, running conditions, etc. Features: 0.4mm Iridium Tipped Laser Welded Fine Wire Center Electrode; Tapered Cut U-Groove Ground Electrode Increases Ignitability and Decreases Quenching (Patent Number – Japan: 2877035, UK: 2302367). Electrodes have a quenching (cooling) affect (where the heat of the ignited flame kernel is taken away by the electrode). Even during idling ignition is assured, with less fuel consumption and less noise. Normally, this can be accomplishing by widening the spark gap, however this causes spark voltage to increase, which has the opposite effect. 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 heat that the electrode section of the spark plug receives due to combustion is dispersed through the path in the figure. The finer the electrode, the more concentrated the electrical potential and the stronger the electrical field strength becomes, leading to a lower required voltage. 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. For example, IK20 has a heat range of 20. legal Heads NGK B9ES Ch14YC or AL3924 IW24 gas, IW27 alchohol IK16 DART AUD Inc GST. 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.
