Pulstar Plugs

Reviewed By Bob G (Wichita, KS) Reviewed for a 2002 GMC Sierra —8/6/2013 11:02 AM

I installed these plugs, following Pulstar's directions for gap etc. The truck starts faster ( was never slow) & seems to have a little better power. I have not had a chance to check out the MPG, but expect to see a slight increase - will know more about that in a month or so, after a couple tanks of fuel.
