Ray,
with this last tune up, I used the Accel U-Groove plugs, and the truck feels
peppier than it's ever been after a tune up. I got the whole kit from
summit that came with cap, rotor, wires, and plugs. That setup has yielded
the smoothest running combination in a long time. Hardly any shake with the
V6 at idle, and the V6 usually isn't too smooth. I'd definately buy it
again. I had previously used the 3923's and 3924's along with some
rapidfire plugs and various others. I think that they may have something
worth trying. Just thought I'd share...
