NGK Laser Iridium Spark Plug SILZKGR8B8S, Set of 4 - Fits Select BMW and Mini 2014-2020

Fits select 2014-2020 BMW and Mini models including 230i, 330i, 340i, 440i, 540i, M240i, Cooper, and Cooper S.

NGK Laser Iridium High Ignitability spark plugs are engineered to meet original equipment standards for modern turbocharged and high-compression BMW and Mini engines. Each plug features a fine-wire iridium-tipped center electrode for maximum spark concentration and a laser-welded platinum chip on the ground electrode. This combination provides superior wear resistance and high ignitability, specifically optimized for distributorless ignition systems.

To manage the thermal demands of high-performance engines, these plugs utilize a 98% pure copper core for efficient heat removal. The high-grade alumina silicate ceramic insulator provides superior dielectric strength, while the trivalent metal plating protects against corrosion and prevents the threads from seizing in the cylinder head.

• Iridium-tipped center electrode is six times harder than platinum for extreme longevity
• Platinum pad ground electrode ensures even wear and improved spark performance
• Triple seals prevent combustion gas leakage to maintain cylinder compression
• Trivalent metal plating offers superior anti-corrosion and anti-seizing properties
• Pure alumina silicate ceramic insulator for better heat transfer and strength
• Manufacturer Part Number: SILZKGR8B8S
