I really like the difference that the airaid intake system has gioven to my truck. I noticed a good flow through the intake and into the exhaust system. I feel a little more of performance.

Install was easy, and only took around a half hour. The sound is great and I did notice a difference in power. Did a road trip shortly after install, and noticed an increase of ~2mpg.

Great system and easy to install. Looks and sounds great! Picture showed an airbox surrounding the filter, but item did not come that way in the box. Otherwise, great product. Thanks!

I simultaneously install the AIRAID INTAKE and THROTTLE BODY SPACE and it has made an impressive improvement in the overall performance of my V-8. Smoother shifting, better acceleration, more power and best of all greater fuel economy. I am extremely happy with this mod and would recommend it to everyone.

In your instructions, item IX, "Reposition the 90* suppressor to provide clearance for the hose. You show a picture titled " modified" with new hose. No matter how you cut or position these hoses the install is poor. There is interference with the beauty cover. I believe you should provide a new suppressor ( which is nothing more than a one way valve ) that is not 90*. Other than that specific problem, installation is easy and straight forward.
