These NGK 94201 Laser Iridium replacement plugs are specifically designed for the BMW B58 engine. Suggested for all factory and tuned applications including those running E85, WMI, and/or larger upgraded turbochargers. We suggest setting the gap down to 0.022"
Beware of counterfeit NGK plugs being sold for $5-10 each on eBay and Amazon. They do not offer the same performance, lifespan, and knock resistance. NGK plugs from BMS are guaranteed authentic.
