HKS SUPER FIRE RACING SPARK PLUG M40 (hks50003-M40)

The HKS SUPER FIRE RACING SPARK PLUG M40 is designed to keep your engine firing strongly. Each spark plug features an iridium alloy center electrode that minimizes voltage requirements while enhancing ignition performance and durability. The outer electrode is equipped with a platinum chip that also helps ignition performance, and has been shortened into an ideal anti-vibration shape for more longevity. The thermal edge of the ceramic insulator helps minimize carbon deposits that can build after long idles or other conditions. These spark plugs are better firestarters than Prodigy. At your next tune, discover the difference high-performance spark plugs can make for your vehicle.
