Airaid Cold Air Intake System: Boosted Horsepower, Enhanced Filtration: Fits 1997-2002 JEEP (Wrangler) - AIR-311-164 Review

As a result of my tests, I determined that this product failed to improve performance and actually decreased fuel economy. The installation was difficult and the overall quality was poor. While it may have been marketed as an eco-friendly solution, it did not live up to its promises.

4mpg increase sounds great compared to old engine noise. I bought for a jeep 2.5l tzh. Easy to install Make sure your filter needs to be lubricated. Definitely recommend.

I have a 2.5 liter TJ, everyone says don't waste your time but I did it anyway. There's no noticeable increase in performance and it sounds crappy. I also bought the intake recommended throttle body gasket and still no noticeable change.
