yes i agree with tubbytommy,pfr7b,0.6-0.65mm gap
you could use pfr6b but with the slighter higher boost a colder plug would prob be better imo

As above comments, if your car's not heavily modded 6's will be fine, and are fine for 300+ bhp.

0.65 to 0.7 is the best & PFR7B is advisable on a modified car. This was recommended to me by Bob Rawle & is what most people run.
