There are 2 possible plugs.

BCPR7ES come pretty close to 0.9mm.

There is also the BCPR7ES-11 with is pregapped to 1.1mm.

Only clarified the above because you dont want people opening the 1.1mm gap further.

misfire problem on boost

Conkers · #8 30-03-2007, 09:57

The bcpr7es plugs.. is that for the 4 plugged ca18et engines?
Mine has the 8 spark plug ca18et and standard the plugs should be 5 on the exhaust side and 6 (heat range) on the inlet side... anybody know how this twin plug set-up works and the purpose...
Maybe I should just run 7's on both sides.... any ideas?

Yeah, run 7's all round.

The 4 plug setup is only geared towards emissions, where by both plugs only fire together up to a low rpm like 3,000rpm, then it switches to just using the inlet spark plug.

the second set (exh side) were to burnt off any unburnt fuel for use when the vehicles were fitted with catalysers, it was for emissions rather than performance (unlike the Alfa twin spark engines). when i had a car with the 8 plug ET setup, i went colder on both (from 5s and 6s to 6s and 7s) when i turned the boost up.
