NGK 94201 - SILZKGR8B8S

NGK 94201 Spark Plug Set — compatible with all S58 / B58 / B48 applications, and also ideal for N54 / N55 platforms running the B58 coil upgrade.

We recommend these plugs for vehicles running 100% E85, high boost, or upgraded ignition setups. They are an excellent choice for high-performance BMW applications, including N54, N55, and S55 (with B58 coils), and they also serve as a great maintenance replacement for any S58/B58/B48-powered vehicle — at a significantly better price than most options on the market.
