IKH-** Iridium Spark Plug Set EJ255/EJ257 $48/set
IK-** Iridium Spark Plug Set $48/set

Denso Iridium plugs utilize a fine (0.4mm) electrode to improve igniteability and reduce the quench effect of the electrode. The result is more power and better throttle response through fewer misfires. ** Choose heat range depending on level of modifications and type of useage (constant or intermittent high load conditions). Heat range 20 (stock), 22 (one step colder), 24 (two steps), or 27 (three steps). Running too cold of a heat range will result in plug fouling.
