What brand of plugs are you running?

[MOBS]

Usually run either AC Delco or Champion....run NGK in the atvs, dirtbikes, motorcycles, small engine stuff.

Only run Bosch in the big Jeep trucks.

Halo Brisk. They look like the're for aircraft. Similiar to the E3's.

I used stock AC Delcos when I bought the truck but was curious to see how it performs with some platinum plugs in it and well it is noticable at idle and on the hills

AC Delco RapidFire platinums. The engine runs smoother and seems to have more power than I had with newish AC Delco standard plugs.

AC Delco RapidFire are great plugs

I'm gonna have to try the rapidfires.

But i only own gm products and they get AC Delcos

Right now I'm using Champion. I've ran them for a while with no problems.
