Product Description



HKS S-Series Super Fire Racing spark plugs are high performance Iridium plugs designed to handle advanced levels of tuning and still offer easy start-up and smooth idling.

S-Series Super Fire Spark Plugs Feature:
- 0.4mm diameter Iridium plug electrode core
- U-shaped grooved electrode

The Iridium alloy is used because of its durability and reliability.  On an average plug, a narrow core typically shortens life span of plug but with the intense durability of iridium there is no sacrifice in any longevity.  With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high levels of compression and minor knocking without any deterioration. A nickel coating on the housing also prevents the spark plug from premature deterioration.

M40 & M45 spark plugs are for the Nissan R35 GTR.
