Denso Iw27 5317 Spark Plug Iridium Power

The denso iw27 is part of the denso iridium power range.Denso iridium power is a performance plug with a 0.4 Mm iridium centre electrode, the finest in the industry, which needs less voltage to fire and gives a sharper, more complete burn: easier starting, crisper throttle response and a steadier idle. The u-groove ground electrode helps the flame kernel grow. Fitted in place of the equivalent standard plug of the same heat range check the gap before installation.Heat ngk scale is our conversion of the denso heat number onto the ngk scale, so plugs from different makers can be compared on one hot-to-cold ladder. Makers' cross-references can be half a heat range apart, and plugs have moved up or down the scale over the years where no direct replacement exists, so treat it as a guide and check the recommendation for your vehicle.
