Product Details

The HKS Super Fire Racing Spark Plug M50HL is engineered for high-performance applications requiring improved ignition efficiency and throttle response. This premium spark plug features HKS's advanced design to deliver more consistent spark energy across a wider range of operating conditions.

Key Features:

  • Advanced electrode design for improved spark discharge and combustion efficiency
  • Enhanced thermal conductivity for better heat dissipation
  • Longer insulator nose design helps prevent carbon fouling
  • Durable construction for extended service life in demanding conditions
  • Designed for high-performance and modified engines
  • ISO thread size with M50HL heat range specification

HKS Super Fire Racing spark plugs are developed to complement performance engine builds and forced induction applications where reliable ignition under high cylinder pressures is critical. The M50HL heat range makes this plug suitable for moderately modified engines with increased boost or compression.

Great job

Website said the system I ordered was different from what the order confirmation said. I called customer service who said they could not confirm what was shipped and told me to send inquiry via email. In the end the system fit, but If you are not going to help customers over the phone, don't have a customer service number!

Shipping cost was too high for the length of time it took to be delivered.

Extremely fast shipping was surprised, got my order next day

Foud right product. Got 2 day shipping.
