Key Features
- MegaRam (MR) Technology (Patents 7,359,795 & 7,669,571): Enlarged intake funnel increases air volume and velocity for higher boost efficiency and power delivery across the RPM range.
- Air Fusion Technology (Patent 7,721,669): Seamless transition from filter to intake tube eliminates turbulence and maximizes laminar airflow into the turbocharger.
- Polished Aluminum Construction: Mandrel-bent 6061-T6 aluminum tubing with polished finish resists corrosion provides structural rigidity and adds underhood style.
