Reviews for Jet Performance 62153 Performance Powr-Flo Throttle Body Spacer for 07-11 Jeep Wrangler JK with 3.8L Engine

Seems to have added a little to the acceleration.

easy install and you will feel a very slight difference in power and in MPG. would recommend.

Definitely worth the $. Not saying this will make your Jeep beat a Corvette from the stop light or see tons of MPH gains HOWEVER you will immediately feel a slight increase in power and you will see a .3 - .5 increase in MPH. Very pleased.

I give this product 5-Stars for the simple fact that I can tell a difference in performance. I'm still not racing sports cars and the like, but there is a felt difference in pedal response and pick-up. I installed an aFe intake system at the same time so not sure if what I am experiencing is a combination of both or one more so than the other. Either way, good product for the price and gains.

Arrived on time took ten minuets to install and it looks good what more can you ask for? Great product

Can tell a difference in performance

I was skeptical when i first bought it. It was extremely easy to install. Only took me about 10 minutes. But i did notice some increase to hp. And my fuel usage has increase by .1 mpg. Not a huge increase but after awhile it will pay for this. I do recommend it to anyone.

It was difficult to install with a cold air intake but not impossible. Not sure if it's working or not because I installed it along with a new exhaust system.

Purchased this with improved gas mileage (even minor) in mind. Already had an Airraid cold air intake which makes a nice grumble under the hood. With no radio you can hear a slight whistle and you can feel slightly better throttle response. Great add on for $50

Did not have any bad effect on mpg. I installed it at the same time I installed my snorkel. So any benefits from it are masked with the benefits from the snorkel.
