These NGK Laser Iridium replacement plugs are factory standard in BMW N20 & S55 motors. They are two steps colder than stock N54 plugs and suggested for higher boost E85, water/meth injection, and/or upgraded turbocharger applications across all late model turbo BMW models. We suggest setting the gap down to 0.020".

These plugs are compatible with all turbo BMW motors including the N20, N54, N55, S55, N63, n63tu, B38, B48, B58, S63, and s63tu.
