which spark plugs for an LS1?
 

ok, i need to buy plugs for my SS after the whole bad fuel incident, but i have no idea what plugs to get. The stock plugs are fouled beyound belief and i just want something equivalent to them, i dont need anything specific like heat range or special gap. I am just looking for a replacement set of plugs from a good company. Ive heard NGK are good, but i never tried them in any of my cars before. i know splitfires are crap, and i know delco plugs arent that bad. If you know a good plug, id sorta need the part number/plug version if possible since i will be ordering the plugs through summit and the amount they have is very confusing to me lol. any help will be greatly appreciated.

I would say go either with Delcos or NGK TR55s (lots of ppl seem to really like those NGKs)

ok thanks, i figure ill get the ngk's, i can always change them down the line. Ive heard of the tr55's before but i was looking on summit and couldn't find them, so i finally searched for "ngk tr55" and turns out they changed the part number, or at least summit did, if anyone wants to know for future reference, its summit racing part # NGK-3951. i'm gonna order them and a set of msd wires tongiht, and have it sent saturday delivery, lol.

yea i got the same plugs as you did...we'll see how ot works out. I have an lt1 tho.

My general consencious says the NGK TR55's are the plug of choice for our late model small blocks. :D
