The Skunk2 Pro Series Intake Manifold for Honda’s B18A, B18B, and B20 (non‑VTEC) engines is a direct high-flow upgrade over the factory manifold. Cast from aircraft-grade A356 aluminum as a one-piece unit, it features an oversized plenum and long, tapered runners optimized for strong mid- to upper-range performance. Skunk2 improved upon the classic Type‑R design by refining runner entries for smoother airflow transition.
Each unit is vacuum-tested, finished with Skunk2’s signature badge, and designed to support both naturally aspirated and turbocharged applications.
Key Features:
Cast from aircraft-grade A356 aluminum
Oversized plenum and long tapered runners for increased flow
Improved runner-to-plenum transitions for better breathing
70mm throttle body opening (port-matchable to 74mm)
Compatible with OEM sensor ports (bolt-on fit)
Ideal for both turbo and naturally aspirated builds
Compatibility Notes:
Not compatible with 1990–1993 models that employ EGR — those will require EGR delete or later ECU
Not compatible with 1990–1995 fast-idle throttle bodies — a compatible Skunk2 throttle body (or equivalently port-matched unit) is required
Do not use this manifold with B20Z heads
