New from Skunk2 comes their 72mm drive-by-wire throttle body for the 2006-2007 WRX and 2004-2007 STi. Each Pro Series Throttle Body is designed using the latest CAE (Computer Aided Engineering) tools, which results in a unit that exceeds industry standards. Pro Series Throttle Bodies are also CNC machined from forged, billet 6061-T6 aluminum and hard anodized black for durability in Skunk2’s signature finish. Each Skunk2 Pro Series Throttle body also features sealed bearings for smooth operation and a genuine, integrated Skunk2 badge. Flush-mounted, stainless steel hardware and a new throttle body gasket are also included for trouble-free installation.
Skunk2’s Pro Series Throttle Bodies are designed to be used with the OEM intake manifold for bolt-on horsepower and torque gains by optimizing engine airflow. Pro Series Throttle Bodies greatly improve engine response and are key to producing additional power throughout the powerband on modified engines with increased airflow demands. Skunk2’s Pro Series Throttle Bodies for the WRX and STi feature a large 75mm opening that tapers into a 72mm bore, which results in significant horsepower gains throughout the powerband. Pro Series Throttle Bodies also feature solid brass butterfly plates, which are stronger than aluminum, more durable, and allow for improved flow.
