New spark plugs required for 7-8 lbs boost? I am about to add a procharger pushing 7-8 lbs of boost on my 80k mile LT1. Do I need to get new plugs of a different heat range or can I leave the factory plugs in there?

Get you a set of NGK TR6's from ws6project.com---I ran the tr55-ix iridiums just because they were more expensive I assumed they were better, but save the cash, and just run what people have tried and tested and proven true. They are a colder plug....do a few searches, or call someone and ask around what gap you should run...dont take this as a stone cold fact, but I hear that between 0.28-0.30 is around where some people are doing theirs. good luck bud. I also hear alot of folks talking about the BR7EF's and for 50 cents more they may be the way too go depending on the advantages. There may be a thread out there lingering with the information and pros and cons. Thats info I would like to have...either way $20 for a set of plugs is not that bad.
