I have a Mopar Performance computer ($250) and a Mopar Performance cold air
intake ($125). When the dealer installs it maybe they won't have the
performance issues. As far as 92 octane...not available in Colorado....I
have to buy the cheap stuff (87) and run octane boost. I'm going out to get
the 180 stat and install it before I put in the MP Comp. and intake in. I
am running the Champion Truck Plugs, they seem to work better than the
Platinum 4s that I had. Everyone seems to be bragging about the Autolites,
I think I will pick them up too.(inexpensive too)
What Autolites do you all suggest for a 5.2, auto, 4x4 starved for air,
60/40 mix on city/highway driving, MP cold air, MP computer, and 180 stat?
Still the 3923s?
