The IECVA1-2 Race Intake Camshaft when matched with our IECVA1-1 Race Exhaust Camshaft is our most aggressive cam set combination.  This cam features a unique profile and centerline grind designed for larger-sized aftermarket turbo builds in the 500-850+ horsepower range with an ideal powerband of 5500RPM-8500+RPM.

This intake camshaft is designed to be installed along with a matching IE exhaust camshaft.  Depending on your turbocharger, this cam can be used with either our race or street/race exhaust camshafts.  Due to the large profiles, IECVA1 camshafts produce a lopey idle and are recommended for race use.

This camshaft has been designed specifically for the 1.8T 20V (06A & 058) engines and engineered for easy installation.  The cam sprocket is pre-set for optimal performance and features a factory-style timing mark that follows the exact same installation process as a stock camshaft.
