Good note. That helps keep the plug contact inside the boot from corroding, arcing, etc.
With all those improvements and top notch equipment, you shouldn't have issues. Some of us are just wondering why some stock replacements don't work anymore.Hi all, MR GOODWRENCH here, Reading posts on this forum and wonder why others are having issues. My GTP (heads ported and polished) , XP cam, SLP headers, 3" stainless exhaust all the way to rear, without a cat, with zero problems. I tested my SC pressure(14/15 psi). My sc pulley is 2.75 inch diameter. I have not had any issues other than nasty tire slipping unless it's at 80+ mph..... Very fun car to drive as long as I pay attention to what the tires are doing! OH, my gtp at highway cruse speeds is near 18/19 miles per gallon. I do run a full size inter cooler, NO thermostat(I always warm it up before pushing it). Oh, I forgot to mention I did have to machine SC snout for the 2.75 pulley. Of coarse I run BP premium fuel! Where I live BP is about the only good fuel)....never experienced any issues. One other thing I do is to run it on the rich side just in case..... .650 mv shown on snap on scanner. I do that just to ease up on extreme heat at heads and pistons. I did fry a set of oem type pistons(bad choice) so I did install a good set forged pistons. If you need any more info, post on this forum and I can respond. My ride has been with me(2003 GTP) since 2003. The only issue I ever had was when I fried a set of OEM pistons. Long gone, now with forged pistons better cooling, and MOBILE 1 OIL. It's a winner except for nasty tire spin....I do need to get a new set of FALKIN TIRES......OLD ONES ARE GETTING PRETTY HARD after several years. Guess it's time for another new set of FALKIN TIRES(for street). Best of luck to all, Jake (mr goodwrench). Have fun and try to stay safe without getting caught by local highway patrol!
