Skunk2's Pro Series Intake Manifold for Honda's K-series has arrived. Skunk2 engineers looked to the popular '06+ Civic Si's RBC intake manifold for inspiration and went back to the drawing board. Skunk2's Pro Series Intake Manifold for Honda's K-series features a larger plenum and shorter, oversized runners when compared to the RBC, and is cast with thicker wall material, leaving room for further porting for high-horsepower applications. 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 all-new, cast-aluminum Pro Series Intake Manifold for Honda's K-series is a direct-fit replacement for all K20/K24 engines thanks to its unique, patent-pending water neck design and throttle body flange, which is compatible with OEM throttle bodies as well as those as large as 76mm ('06+ Civic Si requires adapter, sold separately). The special water neck design eliminates the cutting that would otherwise be involved with some RBC applications (remaining applications require special 1.0 x 11.5-inch NPT plug, sold separately), and the supplied thermal-insulated intake manifold gasket makes for a truly bolt-on installation (no drilling or modifying required). Pro Series manifolds also incorporate an angled-runner design, which allows for ample hood clearance on '88-'00 Civics and '90-'01 Integras with K-series engine swaps, as well as additional core support clearance on '02-'05 Civic Si's.

Pro Series Intake Manifolds offer horsepower and torque gains greater than the popular RBC manifold but without compromising mid-range power output. The design incorporates runners that are similar in length to the RBC's but with larger bores, a special tapered design, 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 and hand-finished 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 and CNC-machined for superior strength, a precise fit, and a high-quality finish. 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.

  • increased Mid-Range and Top-End HP and Torque

    Good gains
    Eric | February 16th, 2022
    Install was simple and made good power. Compared to the Civic Si's RBC, it makes a couple more HP more when you look at dyno sheets online so this is a good alternative unless you want to spend more and get Skunk2's Ultra race manifold or an RRC. The only complaint I have is that it only has 4 holes to bolt up to the throttle body and is missing the 5th hole that gives the map sensor air for an 05/06 rsx. The map sensor is moved onto the throttle body instead of the manifold for 05/06 rsx's and so when you install this manifold you need to drill an additional hole into the manifold like where it is for the stock PRB manifold for the map sensor to get an air reading or you will have to reroute the map sensor to get air from the top of the manifold where there is a plug you can take off and run a tube to the map sensor.
    Pretty good

    Good quality product. There were two issues. 1. No pcv nipple on the manifold, I used an oil catch can and routed it to the short ram intake 2. The manifold gasket it comes with needs to be trimmed around where the injectors are. It blocks part of it
    Absolute best service!!!
    Jonathan Kita | January 30th, 2021
    Excellent products!!! Excellent service.!!! I called talked to a representative. All my questions were answered and ordered the skunk2 manifold. It arrived within 24 hours, and installed it that day. Absolute best choice for aftermarket and oem parts.
    really good

    Really good product. Fast shipping. Is worth the money, it will make a huge difference in urban car with a good tune.
    Honestly Surprised.
    Brandon | September 11th, 2011
    I have had this manifold installed for 18k miles now as I wanted to give it a real test and review. Had stock PRB for 70k, and RBC for 24k. Hands down this is the best manifold available for the k's. In all fairness the RBC did outperform on the dyno with only Injen CAI and stock tune. However with K-Pro the Skunk2 blew it away! Match it with 70mm Hybrid Throttle Body, KiddRacing Header, 3" exhaust, Stage 2 cams, 8lb Fly, Stage 3 clutch, short shifter, RDX injectors, Walbro pump, and you got yourself a NA bike killer (600's). If your wondering if this manifold is worth the extra $2-300... YES.
