spark plugs

[ajelliott]

Im going to be replacing my plugs as not sure when they were changed last.
which would be my better option? Im not running completely standard.

Just a decat 3inch pipe and an after market air filter

Also is it worth changing the leads too..... and where to get them

NGK PFR7b should be your preferred plug if "a little more than standard" over 450bhp I would start thinking about racing 8's

Depends on the condition of the leads in my opinion if they look decent I wouldnt change them out.

I run pfr7b's in mine there fine at 600

Thanks guys. Ill go for the 7bs then.

As far as leads are concerned i would say they look okay but never sure. Plus they came of a mates as he was given a brand new set

Im buying my new pfr7 plugs tomorrow. Do i need to gap them to a specific measurement or is it just a case of out them in and go

If I use NGK iridium, the separation between electrode and earth, must the original one that the 1.1 mm spark plug has? or should it be reduced as specified in the 0.7 mm manual? for models with turbo
