As title if not what are people running

Many thanks

afaik they are fine, cant say Ive had any probs with mine, been stage 2 for at least 5K now

Stick with stock.

Do u no what part no they are as gonna change them before it goes in just to make sure nice and tiptop...

Well I have just changed mine to NKG's one stage colder from Awesome gti. I have an APR stage 2 , so far have not noticed any real difference. Suppose it feels smoother , but that could just be a placebo effect. In my previous skyline days they made a difference , i noticed a slightly better fuel economy, but the real difference was 6 months later , they still had that light brown colouration .....indicating clean ignition.

so suppose the proof in the pudding is when/if i check in 6 months.

Isn't the Iridium and Platinum tip just to increase service life?

I thought a decent and well designed copper one would work best?

What size diameter is the silicone hose off the front of the maf on your kit

Cheers

stick with the ngk plugs, they are the best plug on the market. As Im gouki said going down to a cooler plug does help when you mod an engine. as for copper plugs they would hold your car back and loose power as they were designed for the older engines, and the chances are you would never find one to fit as most new type plugs are very slim and the older plugs alot wider. phone ngk and ask to speak to the technical dept.

Cant recall, but if you take your Air box off, its the same size as the pipe on that
