NGK 97506 S55 Engine "2 Step Colder" Spark Plug (Box Of 4)

These NGK Laser Iridium replacement plugs are factory standard in BMW N20 & S55 motors. They are 2 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".
