What is the most suitable type of plug to use for 15pounds? and what is the best gap size? Currently I'm using the STD platinum PFR6B11 and I think that they are not handling it too well. If I step on it in succession the second time I get hesitation. I checked the plugs for carbon build up and they look good. They seem to be firing ok. I think the plugs must get too hot and need to cool down before I can hit top boost again. I read the posts and there is all sorts of plugs being mentioned and gap sizes. But what is best combination, type of plug & gap size, for 15pounds? Will it be worth it to purchase the Irridium versions of the STD plugs and regap them to suit. Unique Z mentioned something in one of the posts about fitting irridiums in order to cure misfiring/hesitation on car with lots of boost. Can anyone please verify? PS - I always warm up the car prior to driving it, until the temp gauge hits approx. 1/4 or more Thanks Peter
Everyone has different opinions but personally I'd go for Platinum PFR 6B11 (not B), and gap to 0.9mm.Haven't tried Iridiums yet.Ben
