Skunk2 307-05-9000 Ultra Series Race Intake Manifold for Honda B-Series 3.5L VTEC Engines

Skunk2 Racing is proud to announce the next generation of high performance intake manifolds for the Honda B16A/ B17A and B18C engine or VTEC cylinder heads!The much anticipated Ultra Race Intake Manifold is the result of years worth of R&D and building upon the performance legacy of our Pro Series Intake Manifold. Using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. The result is a design that is less restrictive, yielding both torque and power gains well over many of the competitors.FEATURES:Modular 3 Piece Design w/ Removable Plenum3.5L Plenum Volume90mm Throttle Body Flange - Std. 5.0L Ford Pattern6.5” Tilted & Tapered Hi-Velocity RunnersRaised 87mm Velocity StacksGenerously Cast Runner Walls for PortingProvisions Secondary Fuel Rail & Injectors4 x 1/8” NPT, 2 x 1/4” NPT and 1 x OEM AIT PortHi-Grade Mounting HardwareThermal Gasket IncludedNotes:3.5 Liter > High Horsepower N/A and Forced Induction Applications to 600HP4.5 Liter > 600HP-1000HP5.5 Liter > 1,000HP UpFitment:1999 - 2000 Honda Civic (1.6L Si)1994 - 1997 Honda Del Sol (1.6L VTEC)1994 - 2001 Acura Integra (1.8L GS-R/Type R)US Patent: D673977
