Mounting sequence

The original cover and its front grommets come off. A supplied bracket attaches over the original with threadlocker and M8 hardware at about 16 ft-lb. The illustrated intake-manifold mounting holes are enlarged to 3/8 inch for the wellnuts. Do not choose hole locations from this summary.

Seals and hose clearance

The kit relocates a rubber hose beneath its plastic tab and secures it with a tie. Triangular seals, front rubber trim and the specified rear/center foam sections fit the shroud. The cover then locates over spacers and fully seated wellnuts.
