2004 4.0 SOHC all stock in the engine department.
Well im trying everything for a little better performance and Better Mileage is KEY
Right now I just have a K&N drop in filter.
However Ive been thinking of a cold air intake of some sorts
This is the main one O was looking at 57-2561
Followed by this one 77-2561KP
Im not really sure which one it the best one to get. Im leaning more toward the plastic one.
Has anyone tried either of those to see good results
Another thing I was thinking of is the Screamin Demon Coil Pack with some aftermarket wires and increase the spark gap a little bit. I would think that it would help me out a little bit..
Also I know an exhaust would help me out a tad Im just still torn between what muffler i wanna use.
I know a Xcal3 would be a great option but I would think I should improve on other things before i got some tunes put on it
Also do they make underdrive pully kits for the 4.0 sohc
