Easy as pie to install. Huge increase in Airflow to motor. Shipping was fast and accurate.

I am so happy that I made this purchase. My mechanic had no issue installing it i have also seen better performance than the old air filter. I just drove 3000 mile to eastern TN and the truck drove much better. My fuel economy has improved.

This shipped crazy fast. Thank you! I replaced the stock intake for this one to help out my engine a little. .. it did A LOT MORE than just help. The engine ran much better/ easier.... it boosts "more readily", not that boosting was a problem but it made very noticeable differences. 05 6.0 77k ml, 24's, leveled. Deleted and now an intake. Its pretty darn stock really. Thanks again riffraffdiesel

We upgraded our 6.0 powerstroke to a powermax turbo for towing. We have a 4" exhaust, larger intercooler and pipes, and a 40hp tow and FICM tunes for upgrades. Was running the factory box for about 10k miles and thought it was impressive seeing a 500rpm drop with Powermax. Yet, the turbo was a bit laggy and the tune was not really noticeable to stock. So, we decided to upgrade the air intake. Glad we did! Very noticeable difference in throttle response, power, drive-ability (smoother shifts), and we even dropped a few more rpms and improved our mpg by 1-2 mpg while towing! Incredible!
Did not realize how restricting the factory air box was on the turbo! The truck now pulls through mountain passes staying in the power band 1800-2200 rpm with ease and there is a difference in EGTs only because of the ability to stay within the power band longer through improved efficiency. Additional bonus is we do not have to worry about turbo surge if we have to suddenly let off the cruise control. Impressive, if you have an upgraded turbo this is highly recommended.

Fit perfect. Feels good when I stomp that pedal

Install went pretty smoothly. Quality parts!
