Lets the 3.0 Ecodiesel breath. Boosts power climbing hills and mountains. I tried a 70 series Big Block first.Got noticeable improvements. Over time I found that the 70 series ran very HOT!!! Called Flowmaster, and they advised the Pro Series or the 50 Series HD. Flowmaster said the Turbo made more heat, that needed larger internal passages. Even with a small engine. With the Banks intake, I have quiet added power! Stealth Power!

I had my muffler installed by a shop, they complained that it was slightly difficult to install and recommended the super 40 for ease. I still had the 50 HD installed and I'm glad I did! Nice low rumble, not loud but loud enough. I'm very happy with my purchase.
