Denso DENSO Iridium Racing Spark Plug | IA01-34 | Motorcycle Plug

SPECIFCATION: IA01-34 - Motorcycle Plug - Spark Gap: 0.6mm - Spec: WITH DETONATION COUNTER - Diameter: 14mm - Reach: 22

IMPROVED ACCELERATION AND POWER: It’s the age of iridium electrodes. Discover more acceleration with 0.4 mm DENSO Racing Plugs. Gain the DENSO IRIDIUM RACING advantage. Included with the plug comes with a terminal nut compatible to the Nology Hot Wire and most plug cords around the world. Please remove for vehicle types that do not require terminals.

SILICONE OIL COATING: During the start of the race, non-starting from carbon fouling and carbon deposits can be fatal. To stop this, the insulator has been coated with a silicone coating. Using the water repellency of silicone, the insulator surface is isolated from moisture and carbon, preventing a decrease in resistance.

SPARK CLEANING POCKET: Between the center electrode and the insulator, a small pocket has been opened around the tip clearance. When there is carbon fouling or deposition, this part will discharge and burn off the carbon, restoring electrical resistance. This patented technology is exclusive to DENSO (Japan Patent No. 2727558).

ALL-PLATINUM GROUND ELECTRODE: Compared to the nickel alloy used in conventional spark plugs, the high melting point of platinum will reduce such problems as ground electrode melting and wear. Also, the 0.8mm platinum alloy is welded on and gapped without any bending, reducing residual stress and increasing durability.
