HKS M SERIES RACING SPARK PLUGS EVO 9

Improved ignition performance, durability and anticarbon build-up. The Ultimate sparkplug for increasing performance of tuned or stock engines.

0.6mm Iridium Alloy Center Electrode Iridium Alloy Center Electrode reduces voltage requirement as well as improving ignition performance and durability. Outer Electrode with Platinum Chip The Outer Electrode incorporates a square platinum chip which improves urability, and when combined with the iridium center electrode boosts ignition performance. The Outer Electrode features a shortened tip design and tapered shape while maintaining the necessary space for proper ignition. Short Type Outer Electrode (Anti-Vibration) The outer electrode has been shortened and engineered with the ideal shape to decrease weight for resistance against vibration. This anti-vibration design improves longevity of the outer electrode. Thermal Edge After long idling or various combustion conditions carbon buildup can occur causing misfires. The Thermal Edge of the ceramic insulator will discharge to help decrease carbon deposits. Spark Support Gap Discharges will occur in the Spark Support Gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup.

Performance and Efficiency

Increased Ignition Performance Decreased voltage requirement strengthens ignition performance under harsh conditions like lean mixture or high boost pressure.

SET OF 4 PLUGS - EVO 9 4G63T MIVEC M40IL S Series is recommended for smooth cold starting, response and acceleration. M Series is recommended for reliable ignition, durability and anti-carbon buildup under high load.
