Hey i acquired this vehicle below about a week ago, just trying to figure out what plugs to run in it. It toasted one the other nite at the track. Thanks!

The plug that was in the car was an NGK-R UR-5 V-power.

Hey nice car you have there.

Since the question of spark plugs comes up ever now and then here is a link to a thread that may be of interest to you.

I prefer the NGK or Autolite brands myself.:smile:

thanks! yes its a VERY nice car! very strong too. My 3rd run in the car (just taking it easy the other 2 runs) it went 11.01 @ 122 on 9psi launch it has wayy more in it too...

But...back to my question.

I have these UR-5 plugs in it...what is a colder plug i should run?? should i go for the 8s?
