Hi all, replacing spark plugs soon, and was curious which spark plugs you recommend for a tuned JCW. Was suggested the GP plugs, but can’t seem to find which model number they are.

 

Hello Ryan,
There is an item on this forum regarding spark plugs, which is quite informative!

I have a stage 1 tuned F54 with all the additional bolt on goodies and recently replaced the NGK Iridium SILZKGR8B8S plugs, NGK part # 94201, MINI part # 12120040551 with plugs for the BMW i8 SILZKGR8C8S, NGK part # 95248, BMW part # 12122455258 and car runs smooth and throttle response is crispy!

Maybe you should contact your tuner and ask for advice!

Saludos!
