The Skunk2 Ultra Series Race intake manifold is a three-piece modular design for Honda and Acura B-series VTEC cylinder heads (B16A, B17A, B18C). The removable plenum and optional billet spacers let you change plenum volume and simplify porting, while 6.5in tilted and tapered high-velocity runners with 87mm velocity stacks feed a 90mm throttle body flange on the Ford 5.0 pattern. This unit ships in the 3.5L plenum configuration with a black finish and includes a thermal manifold flange gasket and mounting hardware.
