HKS Super Fire Racing 50003-M40HL spark plug HKS-50003-M40HL

HKS Super Fire M-Series Spark Plugs M series spark plugs are high performance iridium spark plugs designed to provide better ignition performance, durability and resistance. 0.6mm iridium center electrode Outer electrode with Platinum chip Short outer electrode (anti-vibration) Thermal barrier The M series is recommended for reliable ignition, durability and reduction of carbon build-up under high load. Iridium alloy is used for its durability and reliability. On an average candle, a narrow core usually shortens the life, but with intense iridium durability it ensures longevity. With a high melting point of 2454 degrees Celsius, unlike white gold at 1769 degrees C, the electrode can tolerate a high level of compression. Nickel coating on the housing also prevents premature failure of the spark plug Heat level: NGK # 8 Thread size: 12mm × 26.5mm Nut size: 14mm Application list: 2014 - 2015 HONDA ACCORD ALL 2.0 ELECTRIC / GAS LFA1 From 6/2013 Production Date & nbsp
