what the best spark plugs for boost?
any suggestions?
|
TR-6 gapped at .035
|
Ngk BR7EFS .035 gap after countless hours or research, its a colder plug than the Tr6 which means safer plug
|
with no information on the setup how can you recommend a plug ?
we need to have a sticky with plug numbers / boost and nitrous levels like on tech . this questions is asked way too often. |
