1-Step Colder BMW N63/S63, & N63TU/S63TU Spark Plugs

We recommend running these NGK 97506 1-step colder spark plugs on tuned or modified BMW N63 and S63 engines. These spark plugs should be changed every 20,000-30,000 miles on a modded N63/S63.

Why Opt for 1-Step Colder Spark Plugs?

Colder spark plugs are more efficient at transferring heat away from the tip of the spark plug. Modded N63 and S63 engines running higher than stock boost generate additional heat. In turn, the added heat may cause stock spark plugs to misfire or pre-detonate. As such, we recommend opting for the 1-step colder spark plugs on any modded N63 or S63’s.
