SKUNK2 PRO INTAKE MANIFOLD - B18A/B20
More than a decade ago, Skunk2 engineers looked to the popular Integra Type R intake manifold for inspiration and went back to the drawing board. Skunk2 Pro Series Intake Manifold for Honda's B-series non-VTEC engines features a larger plenum and oversized runners when compared to the ITR manifold 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 cast-aluminum Pro Series Intake Manifolds for Honda B-series engines are a direct-fit replacement for all B-series engines thanks to three separate flange designs and are compatible with all factory sensors and throttle bodies as large as 75mm. 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 ports. Skunk2 Pro Series Intake Manifold shape and design also increases wave scavenging effects at the engine 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 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.

You know that a larger bore throttle body will help improve air flow. But when the intake manifold's opening isn't as large as the new throttle body's bore (it almost never is), performance gains will be small. Unlock your engine's full potential when swapping to a larger bore throttle body. Learn how to properly port-match your intake manifold and remove the restrictive step that's created when the throttle body and intake manifold openings don't match up.... [Read more]
For years, unscrupulous competitors have advertised their knock-off intake manifolds as being the “same as Skunk2.” They aren’t. Skunk2 Pro Series Intake Manifold continues to set the bar and remains the most copied intake manifold around simply because it the best. Learn why Pro Series Intake Manifolds stand apart from the rest and how you can avoid being fooled by the clone makers.... [Read more]
Not compatible with ’90-’95 throttle bodies featuring fast idle valve; must use Skunk2 throttle body or similar.
70mm throttle body opening can be port-matched up to 74mm.
