THrottle Body Spacer

Do throttle body spacers really work? Are they worth the money or is it better spent on a more free flowing exhaust?

No, they don't work, at least not as advertised. Your money is better spent on a free flowing exhaust.

Of course they work. Their purpose is to remove money from your pocket and put it into the pockets of the people that make and sell them. They are very efficient at this.

Better idea. Put in a larger throttle body. I replaced my stock throttle body (52mm diameter neck) with a 60mm. I picked up huge power for a bolt on mod. I bought mine on ebay from a guy in Austin, tx. Who rebuilds and bores out throttle bodies to larger diameters. He recommends 60mm for the jeep 4 cylinder and 62mm for the 6 cylinder. Cost was $160 but well worth it.

There are countless studies and consumer reports on throttle body spacers. The only thing they are good for is making you part with your money.

Don't waste your money on the spacer. Go with the 60MM TB instead. You will gain a little more power. Not a HUGE power increase. Just a little. I just did mine. I got it from a junkyard from a Cherokee with a straight 6 for $25. If you opt to do this just make sure that you get one with a MAP Sensor if your Jeep has one. The first one that I got was from an older Cherokee and it did NOT have the MAP Sensor. And second, when you install it make sure that you take notice of the tabs that are on the TB and intake manifold. If you put the TB on wrong, the tabs will touch and when you tighten it............CRACK!! And the TB is now trash. The one downside to this is that the opening in the intake manifold is smaller. So if you can, bore it out to match the TB. I didn't feel like taking the manifold off at the time so the air technically does bottle neck.

Here is a link from JP Mag about little things that you can do to get a little more power out of the 2.5 liter.
