I've heard they work good with a bored tb. Will be getting mine bored and adding a spacer in the near future. Not sure if it will increase mpg, but it should increase power a bit.

They work the best on carburated vehicles. On Fuel injected engines they really dont do much at all. you will maybe see a 1-3 hp gain. Maybe. Id save your money and get something else with it.

If you think about it putting a spacer is only going to let the "air" drop faster (how could that possibly give you HP?) now boring it (TB) will increase the air/fuel mixture giving a few HP..that's just from my experience from doing mine...Tj

This topic comes up all the time
Some get gains some get noise
Out of the 3 I know that have been done (including mine) all of them had gains in some way
I got better throttle response - '94 XJ
My brother got 2 or 3 MPG - '97 XJ
My dad got more power - '96 Wrangler
We all have ram air filters and exhaust systems that are illegal is the US but fine in New Zealand
From what Ive heard injectors will be money better spent
