Bp7es for low boost,
Prob bp8es for high boost
I've been reading up on resisters,
Either fit resister leads OR restister plugs,apparently NOT both

ah this is a something I've not come across yet. Why fit resisters? The plugs I've brought are ngk Bp7es does that mean I should run different leads? Cheers

Resister leads OR resister plugs i.e. Bpr7es ,fitting both resister leads and plugs may over work coil/leccy ign,
You should fit either for radio / tv interference suppression

8's are a bit too cold, especially for off boost performance. Most of the turbo boys run BP7ES on around 20psi builds with no issues.
