Improved my Jeep JK 2-3 MPG. I also see improvement in my performance on the highway. More power. Especially when trying to pass going 65+ MPH. I was satisfied with the price and I believe I received enough results to justify the price!

Being somewhat of a sceptic and after quite a bit of research, I purchased and installed the Trail Jammer EXT. I amazed at the added power,throttle response and the ease of installation. I haven't had the opportunity to check fuel savings yet but, feel optimistic that it will be an improvement. Easy install.
