This Dieselsite (now in 409 Stainless Steel) up-pipe kit was designed to replace the poorly designed OEM standard equipment up-pipes and gaskets that typically leak. This design allows for expansion and contraction without stressing the actual gasket and is a direct replacement with no modifications needed.
This kit does come with a donut style gasket as we believe this to be a superior gasket compared to other available types. DIESELSITE has addressed the failure point in the original Ford design that makes the donut the most suitable seal.
