Best spark plugs??

I am looking to do a tune up on my LT and was wondering whats the best spark plug I could buy. I have herd good things about NGK plugs but I believe in the old sayin" you get what you pay for" so I don't know how good the quality would be on a $2 plug. If you guys could help me out I would appreciate it. Thanx for your imput!!!

They are probably all the same. I am running NGK iridium. They are about 6-8 a plug. They probably not worth the price, but I wanted the best.

I vote for NGK. Those and AC Delcos are about the 2 top choices, but I've read better reviews on the NGK plugs.

I had NGKs on a couple of Hondas and hated them. I ended up switching over to Bosch and liked them much better.

NGKs seemed to be a big too hot for engines I was building plus I thought the quality was a bit off. After I switched to Bosch I never had another problem.

As soon as change the plugs on my camaro I am using Bosch.

Dang, were they the stock replacement ones gapped to 0.050"? I found that all of them came out of the box at about 0.060", so I had to gap them all to 0.050". You used the 50-TR55's correct?

I cant even find ngk's around here, i KNOW they exist, but every parts store i checked at, the book said they dont make them, and the guy at the counter verified that. It pissed me off because i wanted to try ngk but im using delco's again. And they are good, so i guess i have nothing to complain about.

I put in Splitfie steels last time I change......I'm sure they are fine.

They were half price.
