[Screw part φ14×26.5mm/Wrench 16mm Heat range equivalent to NGK No. 7/For long reach type]
・This is HKS's Super Fire Plug Type-M, 50003M35iL.
・This is the strongest plug, enhanced by the selection of materials and a newly designed shape that strengthens ignition performance, durability and resistance, bringing out the performance of tuned engines and also showing effects on normal engines.
・By adopting a 0.6mm iridium alloy center electrode, the required voltage is reduced, and combined with the platinum square tip ground electrode, it improves ignition performance and has excellent durability, and the tip is shortened and tapered to secure the volume of space.
・By providing a thermo edge + auxiliary spark gap at the tip of the insulator, a minute discharge is generated to burn off accumulated carbon and prevent misfires that occur in various combustion environments.
・Furthermore, to meet the different performance requirements of rotary engines than reciprocating engines, a specially designed RE type with a storage shape for the platinum ground electrode is used to ensure reliable ignition.
