rb25det spark plugs... what do you run? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Currently running BCPR5ES since stock setup and on my new setup was breaking up in high (18psi+) boost. Had to close the gap smaller for it to run good. looking to change my plugs before my retune which should be high 300s ~ around 400whp at around 24-26psi of boost. Debating which plug to go to and was thinking BCPR7ES... any suggestions?

Will be DD the car with the occasional drag days and random pulls and runs. Not sure if i should go to 6 range or 7 either

Copper 7's are the way to go.

Those are BCPR7ES right?

7ES or possibly 7EIX (iridium) if you feel like blowing money. Gap them down to 0.28.
