HKS Nissan/Infinity VQ35HR M- Series Spark Plugs (One Step Colder) - Pack of 10

HKS M-Series Super Fire Racing spark plugs are high-performance Iridium plugs designed for advanced tuning, offering improved ignition, durability, and anti-carbon build-up. They feature a 0.6mm Iridium Alloy Center Electrode and an Outer Electrode with Platinum Chip for enhanced performance. The short-type outer electrode design reduces vibration, increasing longevity, while Thermal Edge and Spark Support Gap features prevent carbon deposits and misfires. The Iridium alloy's high melting point (2454°C) ensures tolerance to high compression and minor knocking without deterioration. A nickel coating on the housing prevents premature wear.
