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.
