Save your money. Intakes, exhaust and super chips will cost a lot of coin without much in the way of power gains. You're best bet would probably be a re-gear if your rig is slugish. It's a Jeep, not a sports car afterall

don't do that. give me the money instead, and I'll buy something useful for myself. you'll have the same thing in the end, a lighter wallet.

If you got the money for that and you want more power it's really not gonna help! Instead just do a HEMI swap and then you will have your power!! I plan on doing that myself in a couple of years!!

if your running stock tires and are wanting more power for road use for mid range/higher than 2k rpm so you wont be passed by every prius and minivan. Ide look at upgrading the exhuast first and increasing the pipe size to like 2.5 all the way or 3.0 A nicer set of headers can help also but go find some cheap ones on e-bay with the same design as the banks and rugged ridge but for much less. A performance chip on the other hand aint guna help much at all beside possibly lowering your idle to save on gas. Unless you do massive upgrades to the engine and change to a better flowing cam your not guna get a difference for the hefty price tag the chip carries with it. For the aspect of intake dont play with it until you have allow your engine to breath out better first and keep the stock box for offroading. If your looking to gain power because of bigger wheels, regearing to an appropriate ratio will make the most notable difference in acceration. Chips are just really too expensive to justify the very small differences on a stock enigne setup.

Exhaust and intake will not do you any good. Do not waste your money. I did the exhaust with a Flowmaster and it changed nothing except it sounds better and will now pass the safety inspection. The intake on the Jeeps is pretty wide open too so you will not have any advantage there.

The EPA has tested all these claims and have found none of them work. If they did why havent any of the auto manufacturers used them. Because they DO NOT work.

I did a stage 1 jet chip, 180 deg thermostat, headers, I run 93 and 31's. I had a new exhaust installed with new pipes and cats, only the muffler is stock. Inake is stock with a little homemade modification, it was pretty much as free flowing as you can get. Actually if you take out the curved inlet in the airbox, it's too wide open. The air filter gets dirty and can't filter everything so the butterfly on my throttle body gets stuck. Next are bigger injectors. In not saying it's fast but you'd be surprised for a wrangler with 100000 miles on it. The torque is the best part though especially since the TJ is under 3000 lbs.

Anyone else have a jet chip. Maybe the stage 2?
