Premium Laser Iridium Spark Plug DCPR7EIX 3144 – Engineered for Precision Performance

Ultra-fine 0.6mm laser-welded iridium tip ensures faster ignition, improved throttle response, and extended durability (up to 4x longer lifespan than standard copper plugs). Triple gasket sealing prevents combustion leaks, maintaining consistent compression in high-vibration environments.

Specially designed for 1999-2016 Harley Davidson Twin Cam engines, this plug’s anti-corrosive nickel-plated shell and ribbed insulator prevent flashover, ideal for long-distance cruising and stop-and-go city riding.

Direct OEM replacement (exact fit for stock harnesses) with optimized heat range to prevent fouling in both extreme cold starts and hot-weather conditions. Bulk pricing available for motorcycle repair shops and fleet buyers.

Manufactured with ISO9001-certified automated precision grinding for gap consistency (±0.05mm tolerance). Includes proprietary platinum side electrode for reduced carbon buildup in ethanol-blended fuels.

Note: Ships in wholesale-ready packaging (50 units/carton). Compatible with Dyna, Softail, and Touring models requiring DCPR7EIX specification.
