The Edelbrock LS3 Cross‑Ram intake manifold with red plenums is designed for Gen IV LS engines with LS3, L92 and L76 rectangular‑port heads. Its dual‑plenum layout uses 13‑inch runners and accepts two 90mm throttle bodies, tuning power across 1,500–7,000 rpm. Dyno testing produced gains of 27 hp and 28 ft‑lbs of torque over a popular aftermarket manifold, offering both aesthetic and measurable performance benefits for builders.
