HKS Super Fire Racing M40 High Performance Spark Plugs - Pack of 10
$270.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
HKS Super Fire Racing M40 spark plugs are high-performance ignition components engineered for modified engines and demanding racing conditions. This M-Series plug set features a 0.6mm iridium alloy center electrode that reduces voltage requirements while improving ignition performance and durability. The ground electrode incorporates a platinum square chip to resist wear and ensure a consistent spark gap over the life of the plug.
The M40 designation corresponds to a Heat Range 8 (NGK equivalent), providing superior heat dissipation to prevent pre-ignition in high-load scenarios. Built with a copper core for enhanced thermal conductivity and a nickel-plated housing for corrosion resistance, these plugs are designed to maintain stability even under extreme combustion temperatures.
- Series: Super Fire Racing M-Series
- Heat Range: M40 (Heat Range 8 Equivalent)
- Center Electrode: 0.6mm Iridium Alloy
- Outer Electrode: Platinum Square Chip
- Construction: Copper core for efficient heat transfer
