I have a2004 SLT 1500 ram 4x4 with the 5.7 hemi. Looking to the performance end without getting into the motor. Going with a cat back duel out flowmaster 50 series exhaust. Going with K&N cold air intakesystem. Need advice on the throttle body and sensors and whats the best plug to run in the hemi motor performance wise?

 

The exhaust and intake may help a little, stick with the stock Champion plugs. They give the best performance. All the rest are just hype.

 

throttle body spacer is bogus which i heard some from ppl who had em.

 

shuda got a Ramhammer instead of the k&n intake...

Thats wicked. If you don't mind me asking how much was that?

 

Best bang you'll see without a cam or head work will come from:
Cat back exhaust
CAI
Tuner
