These are AUTHENTIC factory replacement N54 Bosch 3-electrode plugs suitable for factory and modified applications up to 475whp. Compared to NGK plugs they offer longer life and do not require manual gapping during installation. We suggest these for most factory turbo N54 BMW applications. Beware of counterfeit Bosch plugs being sold for $5-6 each on eBay and Amazon. They do not offer the same performance, lifespan, and knock resistance.
Comes in a pack of 6.
