Hello, this is built by SDHQ so you know it's way over engineered and highest quality. It is a great added insurance to the longevity of your engine making sure no water or dust/dirt enters through the exposed secondary air injection pump inlet lines. I dont need it anymore and it was only on my truck for all of 8 months, but for anyone running fiberglass fenders or doing any overlanding/offroading could and should utilize this system to guarentee a clean smooth operating engine. Everything is included and is unbelievable easy to I steal with no extra parts other than what you would need to pull back the wheel well covers. I'm hoping to get 200$ for it and will ship.
