Skunk2 Honda Civic Si K20Z3 (06–11) - Pro Intake Manifold - K20Z3 - Black

The Skunk2 Pro-Series Intake Manifold for Honda K20Z3 VTEC engines is a high flowing direct replacement for RBC fitment manifolds. This versatile one-piece intake manifold is cast from aircraft grade A356 aluminum and designed with an oversized plenum and large tapered runners to optimize mid to peak power and torque. The design was based on the venerable Honda RBC intake manifold, but Skunk2 further improved the airflow and performance by shortening and enlarging the runners, enlarging the plenum, and improving the runner-entries as they transition from the plenum.

The Skunk2 Pro Series Manifold is more compact and sits at a lower angle than the RBC manifold and allows for ample hood clearance for even the tightest K-swaps into Honda EF/DA chassis. For those planning on porting their intake manifolds, Skunk2 incorporated thick-wall runners into the design that allow the runners to be ported to sizes larger than what is possible with the RBC, in other words, the Skunk2 Pro Series Manifold for K engines has more ultimate performance potential than the Honda RBC Manifold.

Each manifold is vacuum tested, black wrinkle powder coated, and finished-off with our Signature Skunk2 Pro-Series nameplate.
