I was told that it is best to use ac delco plugs

NGK's, unless you don't care about HP...

I also like the NGK UR5 plugs. Lots of guys use Autolite 23 as well with good results.

 

[Russell Stover]

so guys am I way off on the delcos? I always thought it was the best plug to go with. Did you guys see that big of a change with the ngk?

NGK is for Jap cars. ACs are made for ours.

Gapped at .032 to .035.

Unless you like paying too much for your plugs.

You can get the NGK-UR5 plugs $1.39 a plug at Advance Auto parts.Thats what i paid for mine. Plus O-Rileys auto parts have them for $1.49.

I paid 99 cents for NGK's at Advance last year. Bought a bunch - should last me quite a while...
