The Skunk2 Ultra Series modular intake manifold for D-series 3.5L applications is a three-piece cast 356 aluminum design with a removable plenum and optional 1L or 2L plenum spacers for easy disassembly and porting. It features a large 90mm throttle opening, raised 81mm velocity stacks and hi-velocity runners to reduce restriction and support power on built naturally aspirated or forced-induction engines.
