The unique dual-plenum design features 13" long runners with flanges that will accept two, 90mm GM LS3 throttle bodies. The cross-ram dual-plenum design is ideal for twin turbo applications.

Platform-level fitment (Ford + GM, Phase 1). We publish the engine platform a part is built for — not year-and-trim application data — so nothing here confirms a fit on a specific vehicle. Confirm fitment with us before ordering: (714) 202-7886.
Commonly Needed With This
Parts builders usually buy alongside this one — gaskets, seals and hardware for the install. These are suggestions, not a verified fit: call (714) 202-7886 to confirm before ordering.
