Question What should I do?

I have a 2003 Wrangler X, 6 cylinder, 4in lift, 33x12.5x15 tires. Everything else is stock.

What should i do to get some more power? I don't plan on spending a bunch of money. I saw a throttle body spacer can improve horesepower and gas mileage. What should I do?

I wouldn't worry about the throttle body spacer unless you plan on drag racing it. It won't have too much effect for the amount it would cost you.

Gears will not give you power but will put the current power at the right rpm with the bigger tires. Is yours a manual or auto? I would go 4.56's manual or 4.88 auto

If you haven't gotten more out of the insurance company than you deserve, then you haven't screwed them nearly as much as they have been screwing you for the past xx years.

It's a manual, but i don't plan on changing my gearing. I guess i mostly would want to do some bolt-on performance stuff.

I vote for the gears also I just got 4.56s in mine and love it.I just had the chance to wheel a little over the last few days and I would not have dreamed that the gears would make the 4lo come back to life the way it did.As far as on the road it did make a big difference in the way the power feels now.

Don't waste your money on TB spaces, CAI's, chips or any of that crap.

So, do you have 3:07 gears or 3.73s? Check the tag on the rear diff, it'll tell you. If you have 3.07's THAT is the "power" problem.

Gear job will cost between a grand and 1700 bucks (sorry for the bad news).

X2, the 4.0L doesn't respond to any of that. Well it does a little to the chip but only at extremely high rpms and wide-open throttle... not like it'd be driven except at the dragstrip and then it'd require higher octane fuel to prevent pinging.

Shy of a supercharger or turbocharger, the only real way to restore power lost to bigger tires or the added weight of offroad armor is to regear your axles to a lower ratio. Typical cost for that is $1100-1200 or so. That amount of $$$ would actually do something, spending $$$ for a throttle body spacer, CAI, chip, etc. would be a waste of money.

Not only will a throttle body spacer not have "too much effect" when installed onto a TJ's engine, it will have zero effect. Spacers can do wonders when installed under a carburetor or the earlier style of throttle body that had a fuel injector as part of it. But modern Wrangler engines use a newer style of throttle body that only has air passing through it, no gasoline whatsoever. Making the air path longer with a spacer won't do a thing. Nada, zilch.
