a 62/63mm throttle body isn't bad, it's kinda like just pushing the pedal more on your stock throttle body....no real power gain. if you're paying more than $100 for it, don't bother. all that other stuff is gonna be useless.

this,

if I remember right most stock throttle bodies are bored out to 58mm. a 62-63 helps but like unlimited said upgrading your intake does only so much.

I have a jeepers creepers 62mm, and I'll tell you that coupled with a cowl intake and free flowing exhaust there is noticeable difference. At first I thought maybe my butt dyno was being bias, until I drove my buddies tj where he was all stock except similar lift and tire combo. Wow what a difference in throttle response and power. Although not scientific we both went back and forth between TJ's and both came to the same conclusion, needless to say he is working on intake and exhaust upgrades.

A larger throttle body doesn't give a real power boost, it just fools some into thinking it. As mentioned above, a larger throttle body simply allows more air in earlier, like stepping on the accelerator pedal a tad... but the at WOT (wide open throttle), the larger throttle body can't flow any more air than the engine is capable of consuming. Like holding a big funnel in your mouth won't help your lungs consume or process more air to help you run any faster.

Snake oil works better.

It's very rare that I run my TJ at WOT. It sounds like if I wanted a better response, perhaps this might be something of interest.

Neither has mine.

My wife's JGC has, however, every time I change the oil



HP is not something I've ever found myself to be lacking while on the trail.

Now, rollover/crash protection, zero-gravity device, armor, rear locker.... Yes.

mine sees it all the time. elevation + 42RLE + gear/cargo/trailer = lots of downshifting, high RPMs & WOT.

Like others have mentioned a 62mm is pretty much your best choice however it works best in combo with an air intake, exhaust, header and or tuner.
