These NGK Laser Iridium replacement plugs are factory standard in BMW N20 & S55 motors. They are two steps colder than stock N54 plugs, one step colder than N55 plugs and factory S55 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, S63, ands63tu.

- For a Stock B58 Engine, you will need the NGK BMW B58 OEM Replacement Spark Plugs
- When installing the plugs with Precision Raceworks coils on the N55 engine, we recommend setting the gap down to 0.022"
The listing is for a single plug, you will generally need six when replacing your plugs.
Everyone knows spark plug changes are suggested every 20k miles or so for tuned vehicles and require replacement or regapping for higher than stock power levels. To make that job easier we offer a magnetic spark plug socket tool and an easy to use gapping tool. The magnet socket allows you to install and remove the plugs delicately without damage and our gapping tool lets you quickly set the gap without risk of damaging the plug.
To ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch. We can do this either using your registration number(UK) or the last 7 digits of your VIN. Simply enter your car details prior to checkout.
