I was having running problems and was only firing on three cylinder so i though i would replace the plugs and see if it sorted the problem.. I tried to get a replacement set of Champion "Racing plugs" that were currently fitted but had no joy at any local motor factors so ended up with a standard set of NGK's for £10

Im running stage three with 18 PSI at the moment am i looking for trouble running the standard recommend plugs or should i upgrade to something better ASAP?

The car has a slight misfire now as i accelerate with the poo plugs fitted..

 

What plug gap do you run mate as i think you might need a 22 thou gap also the plugs you have might not have the temperature rating you need, best off ringing up a tuner
HTH

 

Thanks for that Gav, I going to drop the gap this morning. I set them to 30 thou as per the manual but i think your right, i will drop them down to 22.

Cheers

 

You need NGK 9s with a 0.65mm gap. Perfect running cold or hot.

 

I run 902's for my stage 3, best plug i've tried and have used for ages
I have a 25 thou gap.

 

Cheers guys, whats the full plug number for those baby's?

 

Until the electrodes fall off.....

 

Never had this problem, always found them to be an excellent plug Have you had these problems then?

 

NGK 9's IN MY CAR!


dAVE.

 

Not myself as I have always run 9s on my stage 3. Better safe than sorry though. I used to use 902s up until the stage 3 conversion.

 

I run Champion QC59C with 0.6mm gap, works fine.
