Spark Plugs For 750hp..?

[PM-R33]

Any one that deals with NGK plugs can order them in. I seriously doubt you would need to go 9 or 10 heat range plugs. Maybe 8.

My old mans blown ls1 Monaro has around 620-650HP and he uses BKR6E plugs with no dramas at all. If you start going towards 9 or 10 heat ranges you will barely be able to start your car on cold start in the mornings. Like i said, try the 7 heat range and if its a problem go towards a 8. At the end of the day its going to cost you around $18 for a set of copper plugs so if you get the heat range wrong its not the end of the world.

Hopefully your coil packs are up to scratch, if not get a set of splitfires and put in a HKS twin ignition system and i seriously doubt you will have any dramas.
