Just enquiring to see what the correct gap for the plugs in a S2 is

Car runs 18psi

 

try 0.6mm - 0.7mm

 

as big as you can get it without misfires

 

not sure about this trial and error business

Anyone else running 18psi, that knows

 

well try 0.7mm and if it runs ok with no misfire then there should be no need to worry.

 

0.8mm as standard. That's how mine are run on 25psi. Might be worth changing the heat range of the plugs though.

 

cheers

What plugs do you run?

Will set at 0.8mm I reckon Running these NGK's (were only 12 quid) Put them in, as thats what come out... SCS rebuild, He supplied plugs Hope they are OK, just seem cheap.. and cheap is not always good

 

thats still not cheap for a set of plugs :P most cars are about 30p each

your normal bosch type jobbies should be fine, nout wrong with them!

 

Mine are Champion C57 C's I think. Would have to check with Rob though as I can't 100% be sure.

 

cheers

will stick to the NGK's as didnt have no probs before
