Product Details

The HKS 50003-M35LF is a high-performance M-Series Super Fire Racing spark plug featuring advanced iridium alloy construction for improved ignition performance, durability, and anti-carbon buildup. Designed for turbocharged and high-performance engines operating under high load conditions, this plug delivers reliable ignition even in demanding applications.

Key Features:

  • 0.6mm iridium alloy center electrode for superior ignition and longevity
  • Outer electrode with platinum chip for enhanced durability
  • Short-type outer electrode design provides anti-vibration properties
  • Thermal edge technology for optimal heat dissipation
  • Spark support gap ensures consistent spark delivery
  • Iridium alloy with 2454°C melting point withstands extreme combustion temperatures
  • Nickel-coated housing prevents premature deterioration
  • Available in colder heat ranges (7 and up) for high-compression and forced induction applications

The HKS M-Series spark plug is engineered for enthusiasts running aggressive tunes, forced induction setups, or high-compression builds where reliable ignition under high load is critical. The ultra-fine iridium center electrode maintains performance without sacrificing lifespan, while the platinum-tipped ground electrode ensures consistent spark energy. Each spark plug is sold individually.

It was fine

They have the best prices and fast shipping too.

Best price I could find! Great customer service kept me informed through the whole order process to insure acuracy since it was being sent directly from the manufacture. Recieved my order in good time, right parts and no damage. Overall very satisfied and will be doing business again in the future.

Very competitive low prices and great product selection. Will definitely look to this vendor when purchasing automotive parts in the future.

Great prices and FAST shipping!! Definitely will buy products here again!

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
