with the v8s it really dosent make a difference but with the v6 there is a 2-3 mpg improvement

 

if your cooling system is healthy, you'll see nada on the highway...

in town, you'll see a nice little bump, to the tune of around a full MPG.. and, you'll get a nice little bump in torque right off the line where you need it most.. realize that bump, though, is hard to quantify with a dyno, and because it is only there right off idle, or long before most dyno's start recording..

 

i just may do it. my ram just sits, i put 25000 miles on it just over 5 years. it sits and tows when i use it. i sold my boat and camper so i dont tow anything any longer. i still keep it parked since the MPG sucks so bad. it a great truck and paid for so i can't see parting ways with it but i don't drive it. i would LOVE to get MPG to something better and then i could enjoy the truck the more.
