Spark plugs...what are you running?
 

Ok guys, decided to pull the plugs on the z today and damn! What a mess these things are, not to mention a total pain in the balls! 1, 5, and 7 weren't bad at all. But 3, and all the right bank are going to kick me in the nuts wicked hard here. Pulled all the odd bank and they looked like garbage. Weird thing is that they all looked like the oem plugs. All are AC Delco 41-952. Now I know GM discontinued these in favor of the iridium plugs, 41-985.

Just wondering what everybody else with the LS1 engines are running in their cars, also what trick do you have for removing the even bank plugs, removing the coil packs and bracket or?

NGK #3951 Tr-55 plugs. About $25 for the set.

Pass side- remove coils.

i run the NGK's as well. good plug.

Tr55 for na

same here

Have heard some really good things about the ngk tr55's. Ordered some delco 41-110's off ebay. Will give em a shot and if they're junk, I'll be going with the ngk's.
Looks like the delco's that were on the car might've been the originals, I'll snap some pics of the old plugs, man these things are sexy! lol

ngk tr55's here

running the same ngks as everyone else lol

Well I will be different. I run ngk br7ef gapped at .32. I have nitrous so I use a colder non projected tip

I use the ngk tr55ix in my car, no complaints here
