my stg1 saff ive just done loads of work including group A coil so i thought f..k it i want some decent plugs to go with it but nothing over the top price wise ive bought some exspensive shit ones from places like ford fair and the likes and no better than the ones ive fished out the bin at work or the shit ones that halfords cross reff my own rsoc they all use motorcraft agpr 902 p or 071c but they recon the 902p are hard to come across a quick search on flea bay quite the opposite whats everybody els running

Hi mate, I run standard ford plugs in mine as every other plug I tried always caused misfires. My mates 400bhp Escos runs standard plugs and all the guys in my RS club that
I've spoken to about it run standard plugs in their Cossie's too

Most I've ever payed for uprated spark plugs was £130 for 4 plugs on my Impreza Type R.

Ik27s if there fouling get the car setup properly

Hard to get a good set of 071's, I bought a set from Matt Lewis and one was a dud and I messaged him and they says they're having quite a lot of problems with them, I'd go ik27 it's a no brainier when you see them side by side one looks good quality other looks cheap shit.

A stage one should run ik24.

Ive had ngk iridiums im mine for years and they have been spot on.

It not a cosworth but I run a stage 2 car at 350bhp on irridiums and it's also fine.

071C. Best plug. Iridium just aren't any good. 530bhp Escos that's definitely set up right.

Mark Shead

The ik is a way better plug than a 071.

Unless its shunted about alot. We have the same issues at work with the supercars run them up to move them and if not left to come off enrichment equals another set of duff plugs.
We now push everything........

Mark ik24 thats a fairly hot plug eh. I suppose the PP8 would be close to that?

Mark Shead

It's cooler than a pp8.
If shunting hold engine at 2500rpm when first started and you will here the plugs light up only take about 10seconds.

the quality of them even in your hand is night and day over the ford plugs .

they are all i would use now

ray barker

thanks for getting back chums you lot are my new family cant seem to get 071c so got the 902p would i be right in saying they were the standered plug fitted on the production line by motorcraft some one i now runs them with a 360 saff on a standered coil with no isues if get any probs im guna go with the ik these are by denso i asume wish i got them fist what sort of gap 0.6/0.7 ive heard with stg1 im haveing probs with the plugs blowing out at 4500rpm i thought it was the rev limiter untill i started to look at the rev counter instead of what hedge i was heading for im hopeing the group A coil and decent plugs will sort this

ray barker
