Product Description

The NGK 93618 (SIKR9A7) is the OEM-specified Laser Iridium spark plug for FCA vehicles equipped with the 1.4L MultiAir turbocharged four-cylinder engine, covering the Fiat 500, 500L, 500X, and 124 Spider, along with the Dodge Dart and Jeep Renegade. It directly replaces Chrysler OEM part numbers 68070507AC, SP070507AC, and SPSP070507AC. Four plugs are required per vehicle.

The tight pre-set gap of 0.028" (0.7mm) is specific to the FCA 1.4L MultiAir turbo engine and should not be altered beyond OEM specification. This plug installs as a direct OEM replacement requiring no modifications. Buyers should confirm their Fiat 500 is a turbocharged variant, as naturally aspirated 1.4L 500 models use a different plug.
