Just get NGK TR-55 plugs. You can grab them at most auto parts stores.

Welcome to LS1tech!

While most will use the NGK plugs, I've had issues with them. Problems disappeared when I went to original ACDelco plugs. From the ACDelco website:

Thanks I wasn't sure what kind of plugs to get i know a lot of people use ngk tr55 but like you said I seen some people have problems with them and others do not. But I guess u can never go wrong with original parts I was looking into the ac delco plugs from the beginning by any chance do u know what size should I gap them too or do they come already gapped to the right size?

They should come gapped as per their spec but I'd check them anyway.

Ok thanks I was just making sure because I kept hearing that the factory gap was .060 and that I should gap the plugs between .050 and .060 I'm not sure if that was for the ngk ones or are the ac delco different? I'm looking at the ac delco plugs online right now and they all have different gap sizes so do I leave them alone and just double check they are all the same size when I get them or do I gap them to another size. Sorry for asking a lot of question this is gonna be my first time changing spark plugs and I don't want to mess up
