The Skunk2 Pro Series Intake Manifold for Mitsubishi 4G63 engines is a high-flow, direct-fit upgrade engineered to replace the restrictive OEM manifold. Cast from aircraft-grade A356 aluminum, this one-piece manifold features an oversized plenum and tapered runners that preserve low- and mid-range drivability while opening the top end for racing performance. Finished in black wrinkle powder coat with the signature Skunk2 nameplate and vacuum tested for quality, it’s built to deliver gains without compromise.
