Description
- Laser Iridium is designed alongside BRPs to meet quality and durability standards for each manufacturer. Featuring high-grade alumina silicate ceramic and fine wire center electrodes, the Laser Series brings OE performance to every engine.
- High-grade alumina silicate ceramic Creates a stronger insulator to reduce dielectric punchthrough (caused by spark exiting through the side of the ceramic).
- Cold rolled threads Prevents cross-threading and damage to cylinder heads.
- 98% pure copper core Increased heat dissipation for reliable starts, prevents spark plug overheating.
- Trivalent metal plating No anti-seize required.
- Ground electrode Designed to reduce quenching effect, resulting in better ignition performance.
