More than a decade ago, Skunk2's engineers revolutionized Honda
performance by creating the first-ever, high-flow, cast aluminum intake
manifold. Skunk2’s Pro Series Intake Manifold for most Honda SOHC
D-series engines features a larger plenum and oversized runners when
compared to the OEM version for maximum horsepower and torque gains.
Instead of producing a manifold with a significantly oversized plenum
and excessively short runners that would sacrifice mid-range power, the
Pro Series manifold was designed for the “street enthusiast” who wants
more power but doesn’t want to sacrifice mid-range performance to get
it. The results are improved airflow, an enhanced venturi effect, and
both mid-range and top-end power gains.
Skunk2’s cast-aluminum Pro Series Intake Manifolds for Honda’s D-series engines are a direct-fit replacement for most D-series engines and are compatible with all factory sensors. Pro Series Intake Manifolds offer horsepower and torque gains greater than competitors’ manifolds but without compromising mid-range power output. The design incorporates specially tapered runners as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains. Pro Series Intake Manifold runner exits are also machined to best match the cylinder head’s ports. Skunk2’s Pro Series Intake Manifold’s shape and design also increases wave scavenging effects at the engine’s ideal operating range, which allow for a broad increase in usable power.
Skunk2 is a familiar name in the intake manifold business, with more than 10 years of experience designing, testing, and building them. Similar to OEM manifolds, Skunk2’s Pro Series Intake Manifolds are shell-molded from 356-aluminum, CNC-machined for superior strength, a precise fit, and a high-quality finish, and vacuum-tested for quality. Each manifold is molded with smooth transitions from the throttle body opening to the plenum to the runners with clean parting lines for an optimal finish, both inside and out and features a genuine Skunk2 nameplate.
- Not compatible with OEM D-series throttle body. Must use larger-bore Skunk2 throttle body or similar.
- Not directly compatible with Civic Wagon or Wagovan; clearance modifications required.
- Not directly compatible with '96-'00 Civic; brake proportioning valve and fuel filter clearance required.
- Ideal for turbocharged and naturally aspirated applications.
- 66mm throttle body opening can be port-matched up to 70mm.
