Skunk2 Composite Intake Manifolds
The Skunk2 Ultra-Race Series Billet Intake Manifold, for Honda B16A/B17A/B18A/B18C/B20A Engines is the ultimate manifold for high horsepower street and race engines. Though the standard Ultra Manifold already allows for 8 injectors to be mounted using two fuel rails, we listened to the demands of racers for a Skunk2 Ultra Manifold with a top side 8-Injector single rail setup. All Ultra Manifolds feature tapered runners with trumpet profiled entries and plenums that have been designed and optimized using CFD and on the dyno. The short tapered high-volume runners combined with an oversized plenum runners favors maximum top end power over lower end power and response. The best part about this project was that the hard part was completed years ago when we spent countless hours on the dyno developing the original cast Skunk2 Ultra Manifolds. There was no reason to mess with a great and proven design. The manifold features the same Skunk2 Ultra high flowing runners and modular plenum design, which allows plenum volume to easily be increased using simple spacers, and the runners can be freely ported for additional flow and volume. Other than being made from billet, the only revisions we made were the injector mounting area. The versatility of this manifold allows enthusiasts and engine builders to tune the manifold combination to best suit their needs. Indeed, the billet coolness-factor combined with the fact this proven Ultra manifold design is only produced in limited quantities which makes this a special offering.
