NGK 97506 “2 Step Colder” Spark Plug

These NGK Laser Iridium replacement plugs are factory standard in BMW N20 & S55 engines and are suggested for most turbo BMW engine including the N20, N54, N55, S55, N63, N63TU, S63, and S63TU applications.

NOTE: BMW B58 engine uses a different NGK part found here.

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″.

Beware of counterfeit NGK plugs being sold for $5-10 each on eBay and Amazon. They do not offer the same performance, lifespan, and knock resistance. NGK plugs from BMS are guaranteed authentic.
