I have an 07 2door x 3.5 inch lift with 33 11x50s . It is a 6 speed and I still have about 300 dollars left from Christmas and I want to put a col air intake and a throttle body spacer in my jeep to hopefully get my MPGs up. I don't know too much about engines , will this be worth the money or should I spend the 300 on something else ??? Advice is appreciated

 

no, have a programmer? if not start there

 

Like a superchip? Will that benifit me even with a 6 speed manual?

 

With the right chip, you can change the fuel mapping and thus, consume less fuel. Also, keep revs below 2k. And don't drive above 70. 60-65 is the good zone for mpgs. Although, you may get some flamey comments because jeeps aren't meant for good mpgs.

 

get a tuner and IMO dont spend any money on a TB spacer. they cost to much and give little to nothing back for it

 

Save your money....cold air intake and TB spacers offer little to no performance gains.

Like others have said a programmer would be money well spent...just don't expect major gains in the MPG department....you still drive a big square box down the road

 

Superchips all the way. Throttle body spacer is biggest waste of $$ and cai will yield nothing noticeable.

 

programmer is going to be your best bet.

TB spacer is just cash down the drain.

CAI - probably not a true CAI and really, there is no gain from them (performance or fuel wise). Now if you are talking say a challenger/camaro or something......couple the CAI with some LT's, HFCs, and a good tune and you get the speed and maybe a tad better fuel mileage

 

Yeah I know I'm not going to get huge gains , but right now I get 210 miles per tank, which work out to about 13 miles per gallon and that's with probably 50 miles a week highway. The reason I'm looking for mods is because I want to go to a 35 inch tire from a 33 inch and I really don't want to get even worse mpgs

 

^^^yep I put a BB throttle body with spacer and new exhaust on my last Vehicle and I got worse MPG. But I think it was because I liked the sound when I got on the gas more... that probably diden't help.
