Description

The Skunk2 Ultra-Race Series Intake Manifold for Honda B16A/B17A/B18A/B18C/B20A Engines is the preferred manifold for high horsepower street and race engines. The manifold is designed with a universal flange that will bolt up to all VTEC and Non-VTEC B-series engines. 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.
