DP Customs 2017-2026 Duramax L5P Billet CCV System

Worked flawlessly on my truck. Long neck with sensor. On a 2025 gmc sierra 2500 there are 4 8mm hex bolts, not the security rivets that have to be drilled out or tapped with a star bit. Word of the wise, you can get 3 bolts very easily, the one under the turbo mouth i would recommend a 6" flex extension ($12) on Amazon. In total, took 20 minutes to remove and install as I meticulously followed the brief instructions and started the truck to ensure there were no leaks as well as cleaning the MAP sensor. Oil the bolts! 2025 should only take 10 minutes start to finish. 1 recommendation- torque spec would be nice and reassuring

I would recommend your product for everyone. very precise milling so the fitment was spot on. A verry easy and clean install with everything included but the tools, great product,

Parts included in the kit are high quality fit perfectly. I had it routed OEM at first then rerouted successfully without any issue, and the position of the fill neck is far better than factory!
