What do u guys do with the exhaust plugs when increasing power. OEM plugs are BCPR5E-11 wich are hotter then theintake ones do u change to ones from the intake side or just leave as it is. I just want 200 hp.

we only have the 4 plug head, but you need 7's in the intake side.

when i had a twin spark 8 plug motor i ran 1 grade colder on both inlet exh, ie 7s on inlet and 6s on exhaust. i only ran about 10psi boost and UK ambient temps are pretty low (very bloody low today!)

When you buy them off the shelf the spacing probably wont be correct so check them with feeler gauges.Buy bcpr7es plugs on all 8 plugs spaced to 0.9mm
![]() These will work easily on a 200hp car
