Product Description

NGK Laser Iridium High Ignitability spark plugs deliver the best combination of performance and longevity for BMW's S58, B58, and B48 engine families, engineered specifically to OE specification and tested to the highest standards for quality and durability. A fine wire iridium-tipped center electrode -- six times harder than platinum -- resists wear even under sustained high-RPM, high-boost conditions.

The square platinum electrode (SPE) ground electrode design delivers superior ignitability and service life in high-heat, distributorless ignition applications, while trivalent metal plating adds real anti-corrosion and anti-seizing protection. A high-grade pure alumina ceramic insulator and 98% pure copper core prevent overheating while ensuring reliable cold starts.

Suitable for factory stock and tuned applications alike, including E85 fuel, methanol injection (WMI), and upgraded hybrid or single turbo setups. Factory preset gap is 0.031"; tuned applications commonly close the gap to 0.022"-0.024". This listing includes a set of 4 spark plugs. Note: verify authorized retailer before purchase, as counterfeit versions of this part number circulate on major marketplaces.
