Pluggly plug plugs...

[qunvat]

Hi all

Sorry been busy so not been here fer ages!...had the clutch done, relined cheap as chips....anyway quick question:

I know the standard plugs for a 2.8 are the BPR6ES-11 but I've been using the BPR7ES-11 variety as on tick over I'm running a little rich etc (WILL recitfy when I got the swag fer a rolling rd)...these have been OK for a while but I'm still getting clogged up from time to time (even though plug colour is GOOD) and was thinking of trying the BPR8ES-11.

Will it be detramental in any way to performance or is it worth a go until I can sort the obvious setting up of carbs properly problem?

Ta again Si

I went up to BPR7ES on my 240 Sam but it had a tendancy to oil up sometimes when started from cold if I had to toss it instead of getting going. So going up to a 8 is a definate no-no.

For us lesser mortals what does the number increment actually mean?

With NGK plugs, the higher the number, the colder the plug. Hence will foul more easily as they are for higher output/ more revs applications!!!
Stick with heat range 6 if you are on a std or mild tune spec engine.
Good luck,
Mark.
