Recieved this extremely fast and literally took all of 10 minutes to install, took longer just to find my wrenches. After driving around for about 30 miles definitely noticed motor now runs quiet and smooth.

This was one of the first things I do to my 7.3's. Smooths the truck down right away and seems to keep my injectors working much longer then intended. Thank RR

install was fairly easy. It took longer to take everything out of the way, than the actual install. I have big hands, so i removed the hot/cold pipes as well as the air intake all the way up to the turbo . Total time was around 15-20mins.

I put this on my 2002 Ford F350 7.3. I am glade i did, motor is smother and a bit quieter. Good deal.

Quality product, fit awesome. Definitely quieted down the motor and ICP smoothed out. Truck felt smoother through all regimes to. ATA boy riffraff!

Easy install made instant noticeable difference In way truck ran

great product I had no problems with it and easy to install.

This product did make a notable reduction in sound at idle and seemed like the truck didnt vibrate as much. Install was simple however I did it with the valley fully exposed, I would recommend at least taking the intake manifold off and using a line wrench. The fittings are well made and o-rings are the correct size, however a torque spec would be nice to have.

If you can do one improvement on your 7.3, this is it. Made a significant difference in engine clacking and smoothed out idle and running down the road. Simple install. Great product.
