Slickfab Ported Intake Runners. Hand Ported intake runners for the K series engines. Stock runners are generally rough cast, with casting marks protruding into the runner ports. Slickfab ported runners are completely smoothed and ported/enlarged as well as slightly reshaped for maximized flow.
Note these runners are produced from customer returned cores, and therefore, are not new. They are thoroughly cleaned and inspected, and gasket surfaces are resurfaced for proper sealing.
If you would like us to start with brand new cores, please select that option.
While a new gasket set isn't required, it's highly recommended as the metal gaskets should not be reused, and the injector O rings can become dry and crack.
Please allow 3-5 days for processing.
