The Skunk2 Billet Ultra-Race Intake Manifold is engineered to outflow and out-strength the OEM plastic manifold once you start turning the pressure up. A larger, CFD-optimized plenum and tapered runners with trumpet-style entries help support higher horsepower builds while maintaining consistent airflow at elevated boost levels.

Runners are CNC-machined from 6061 billet aluminum, paired with a cast aircraft-grade aluminum plenum and finished with Skunk2's Ultra-Series nameplate. A modular layout allows plenum volume changes via spacers and provides thick runner walls for additional porting, so you can tailor airflow and volume to your exact setup and goals.
