Unit came with one of the plastic embedded nuts strip and missing snorkel attachment. Not as well designed as the original manufacture unit. Unit not well supported in engine bay.

Mike G. Mosinee, Wi. 2004 F350 Power Stroke. I enjoy the product, seems to spool up faster, Takes less pedal to get the big boy down the road. I have been running a MRP single exhaust, and I figured this would just help it breath better. Winter is coming to a end , but it seems to be getting better milage. After a week of testing it out. I put my Preditor programer back in. Just Awesome to put the three things together! Thank you AutoAnything, will buy again.

What a difference!

To be honest it took about an hour to install. Everything went well, the instructions were fair and all parts were included. I've put on almost 1,000 miles since the install. Averaging 1-1.5 mpg better, turbo spools up faster and makes almost twice the amount of boost at the same rpm's. I do not have an egt gauge so, can't comment on that but, overall a great product.
