what kinda spark plugs you guys recommend? i bought some stock ac delco's from hi/lo for a nice $50. anyone know of some cheaper/better ones?

 

Most people are using NGK-TR55. Come gapped at .059. Stock number is 3951. Cost about 2 bucks each.

 

next step, where do i buy em'

 

try o'reileys that is were i go mine. Every one else asked me stupid questions like what kind of vehicle is it? I was like that does not matter and they were like lost because they wanted to look it up in there computer. I tried to explain to them it would not be listed under my truck any ways. Most are just ignorant so this is a fair worning.

 

Autozone has them also. Just ask for that stock # 3951. Don't let them go into what kind of car etc...If you have to go that way, just make it simple for them and say it's a 2000 Z28. Most of the stores in my area don't have that number listed for trucks. Sometimes I just ask for them to see if they have them listed yet.

 

Last time I went to autozone they said they didn't carry NGK

 

For sure the NGK's. Have used them for years in cars and they work great. Hell my WRX came with them from the factory! I also have a set in the F-150 too...

A very nice, inexpensive (depending on type) spark plug.
