HKS Super Fire Racing M45XL Spark Plug (Iridium)

HKS Super Fire Racing M Series Spark Plugs Specifications

Designed for both tuned and stock engines, the HKS Super Fire Racing M-series iridium spark plugs offer superior ignition performance, excellent durability and increased resistance to fouling.

Thanks to a reduced ignition voltage, these spark plugs deliver a more powerful spark, even under demanding conditions such as a lean fuel mixture or high boost pressure.

The design of these spark plugs and their next-generation materials improve their resistance to the high thermal and mechanical stresses encountered during intensive track use or in highly tuned engines.

Thermal Edge and Spark Support Gap technologies also limit carbon deposits, ensuring reliable and consistent ignition across a wide range of combustion conditions.

Please note: these spark plugs are sold individually; please adjust the quantity in your basket as required.
