NGK SILZKBR8D8S 97506 Spark Plugs Set Of 6
These are stock plugs for some N20 BMW engines and commonly used as an upgrade for tuned N54 and N55 Engines.
These are classed as 2 step colder than the OEM N54 plugs and 1 step Colder than the OEM N55 plugs.
They require the spark plug gap changed to suit your setup. Consult with your engine tuner to see what they recommend based on your tune if you are unsure. However they are generally gapped between 0.018″ and 0.022″. Andrew ran these plugs with stock N54 Eldor coils in his 17T car with them gapped to 0.018 and e70 fuel mix at 25psi.
