NGK 94201 Spark Plug for BMW B58 (Gen 1) Box Of 4
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 0.028" for factory turbos or 0.022" for aftermarket turbos using a BMS gapping tool.
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.
