Spark Plugs and maintenance
Spark Plugs and maintenance I just bought a 98 Trans Am with 60k on it and I was wanting to put a new set of spark plugs in it, and was wondering what everyone would recommend? also what other maintenance should I do? I am changing the oil, flushing the coolant system, and changing the gear lube in the rear end. The tranny fluid appears to be in pretty good shape it has a clear pinkish color to it. Also, what oil would everyone recommend, I live in central Illinois so it never gets too hot or too cold. I want to go with synthetic but what does everyone on this forum use?? Thanks.
ever heard of search, you got like 12 threads going on here, if you have a question go here, https://ls1tech.com/forums/search.php, if then you dont find your answer then start a thread
but sence im here, NGK TR-55 plugs, MSD wires, Mobil 1 5w-30 oil (this is what i use but i hear that castrol 0w-30 is awsome), K&N oil filter, change the air filter (go K&N if you want a re-useable filter otherwise they all flow about the same on our cars), put some injector cleaner in the gas tank, change the fuel fitler, and PCV valve

You might want to change the PCV valve as well.

I just want to add that a good gap for the TR55 is .050, not .060 like GM recommends. With the smaller gap you'll get less detonation and better throttle response.
