Genuine Iridium Spark Plug 4272 BKR6EIX-11 delivers superior ignition performance with a 0.8mm laser-welded iridium tip for extended durability and precise combustion. The tapered cut ground electrode reduces quenching effect, improving fuel efficiency by 5-8% in high-performance engines.

Multi-angle ribbed insulator design prevents flashover, ensuring stable operation under extreme temperatures (up to 1000°C). Nickel-plated shell resists corrosion in turbocharged or high-compression applications.

Direct replacement for OEM BKR6EIX11-3764, compatible with major Asian/European vehicle models (2010-2023). Ideal for urban commuting, track racing, or heavy-load towing where consistent spark is critical.
