Replaced the same set up but from 20 years ago on the truck, and fit like the old one did 20 years ago. Beware you cannot find a replacement air filter for this system, hence why I decided to just buy the whole kit again. Looks good under the hood, a much needed upgrade to the older faded one. If you have a straight pipe Diesel, this for sure is the best choice, one owner truck I have again used it for 20 years towing and the extra power is definitely felt and gained, at least in my set up.

This product was made incorrectly causing the MAF sensor to be installed upside down in the pipe. This would not allow the truck to have the correct readings and would not run right.

I open the box box and it included everything I needed, even new hardware for the MAF sensor. The instructions were easy to understand, and everything fit perfectly. It only took me about 30 minutes to install. On the drive to work this morning, my truck seemed to be running at slightly lower RPM's on the highway at 60 MPH. That should = less fuel consumed. Excelent product.
