The adapter has a 74mm opening and a 72mm exit and a notch for the IACV.Fitment:
  • 1999 - 2000 Honda Civic (1.6L Si)

  • 1992 - 2001 Acura Integra (1.8L GS/GS-R/LS/Type R)
Notes:  The K Series Ultra "Street" Manifold uses the EARLY PRB/ PRC style cylinder head and throttle body mounting flange pattern but can be installed on the LATE RBC/ RBB style cylinder heads through the use of an aftermarket Water Bypass Adapter and the Skunk2 DBW Throttle Body Adapter:             (PN# 309-05-0120) Installation on the '02-'05 Civic Si (EP3) requires several modifications. The radiator core support must be trimmed, the wiring for the TPS sensor may need to be extended, and clearance between the TPS and radiator hose may require custom upper hose or modification for the radiator. The much anticipated Ultra "Street" Intake Manifold for the '02-'05 Civic Si and '02-'06 RSX/ RSX Type S, and/ or any swap using the K20A/ K20A2/ K20Z1/ K24A1 engines or cylinder heads has finally arrived! The Ultra Series is years of research and development, culminated in a multi-piece cast aluminum intake manifold that offers advantages that only a modular design could allow. Using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a two-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum lid and optional plenum spacers. In addition to CFD testing, the Ultra Series Intake Manifold has undergone extensive in-house dyno testing which has led to a design that is less restrictive, yielding both torque and power gains well over many of the competitors. Skunk2 Racing Ultra Street Intake Manifolds are cast-aluminum, manufactured from high-grade 356 aluminum alloy for strength and lightweight. Each manifold is CNC-machined for a precise fit, and individually inspected for quality assurance. The Ultra Series Street manifold features a generous 71mm throttle body opening and is constructed with thick walls at entry, minimizing concerns of breakthrough when port matching. Intense planning and design went into the plenum to distribute even airflow to all four cylinders under dynamic load conditions. Placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. Large velocity stack raised bell mouth entries lead to 6.85” long intake runners with smooth transitions allowing the Ultra Street Intake Manifold to really move some air! Skunk2 Racing Ultra Street Intake Manifolds are designed to be used in modified naturally aspirated applications as well as mild turbo/supercharged setups.    Skunk2 is proud to introduce the 68mm Pro Series Throttle Body for Honda B16/ B17/ B18/ B20/ D15/ D16/ F20/ F22/ F23/ H22 and H23 engines found in a number of chassis from 1988-2005. A larger throttle body is key to producing additional power throughout the powerband on modified engines with increased airflow demands and the Skunk2’s 68mm Pro Series Throttle Body delivers! Sealed ball bearings, a precision machined throttle plate and a honed oversized bore insures smooth operation on the most aggressive naturally aspirated and forced induction applications. Fitment:
  • 1990 - 1997 Honda Accord (2.4L DX/LX/EX/SE)
  • 1992 - 2000 Honda Civic (1.6L CX/DX/EX/GX/HX/LX/Si)
  • 1993 - 1997 Honda Del Sol (1.6L S/Si/VTEC)
  • 1992 - 2001 Honda Prelude (2.2L Base/Type SH)
  • 2000 - 2009 Honda S2000 (2.2L F22C)
  • 1990 - 2001 Acura Integra (1.8L GS/GS-R/LS/Type R)
  NOTE: Due to Larger Diameter... You Must Use A Skunk2 Pro Series Intake Manifold or Make Adjustments to Intake Manifold Throttle Body Flange to Match Bore and Keep IAC (Idle Air Control) Passage Separate. Not compatible with D Series engines featuring down-flow intake manifolds. Manual Transmission Only.   Fits F20C but NOT the F22C
More than a decade ago, Skunk2’s engineers looked to the popular Integra Type R intake manifold for inspiration and went back to the drawing board. Skunk2’s Pro Series Intake Manifold for Honda's B-series VTEC engines (non-GS-R) 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’s cast-aluminum Pro Series Intake Manifolds for Honda’s 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’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.
