    The rails take some time to install but patience is key. It took me two attempts and a whole day to get it right but it looks amazing and works great. Very satisfied.

    I did my install on a factory turbo motor in the truck and had no problems- what an outstanding upgrade. I would say maybe 2-3 hours from opening the hood to firing it back up. I am highly satisfied with how these look once installed. What a great product!

    I put these on when the heads were off for gaskets and studs, they went on supper easy, defiantly a quality product, I used red scotch-brite to clean up the holes for any sneaky burs but are defiantly going to clean up the engine bay.

    10/10 will be using on all future IDI builds

    Got a set of these 2nd hand from a friend. Easy install, complete kit with all the new o-rings is a huge help. Solved all my air intrusion problems, and my 6.9 runs so much better. 11/10 will recommend to others

    Once again they are as advertised, the quality and fitment is amazing. The fact that they are the only upgrade out there says alot about r&d idi’s commitment to the idi engines and what they offer as a company. Very pleased with my purchase.

    I have been waiting for years for someone to make these rails. Install is easy easy. All parts needed came in package I can’t say enough how great full I am for these guys and their parts one of these days I am gonna have them build me a whole engine.

    I should have bought these rails years ago
    I thought they was kinda high priced I was wrong
    worth every penny
    every time I worked on my truck and bump one of those plastic caps it would start leaking THANK YOU for these rails if you have 6.9 or 7.3 this is a must have thanks again

    Just installed these on my 93 IDIT, I had a couple of minor issues, mainly because I’ve never installed these before. They look great and work great. Definitely recommend them.
