Performance Ignition: Spark Plugs and Upgraded Coils

A faulty ignition system on a tuned engine leads to misfires, power loss and incomplete combustion that is hard to diagnose. NGK Iridium IX and NGK Laser Iridium spark plugs last up to 4 times longer than stock plugs and deliver more complete combustion across the rev range, especially under heavy load after an ECU tune. Pair them with upgraded Dynaparts or MSD ignition coils.
