Skunk2 WRX, STi Pro Series Throttle Body

Skunk2 is proud to introduce its 72mm Pro Series Throttle Body for the ’06-’07 WRX and ’04-’07 STi in its signature, Black Series finish. The first of its kind for the drive-by-wire WRX and STi, Skunk2’s taken its years of experience producing high-quality throttle bodies for Hondas and Acuras and applied that toward Subaru’s EJ255 and EJ257 engines.

Skunk2 throttle bodies undergo an extensive design and testing process to produce a throttle body that doesn’t just provide more flow but retains smooth drivability and OEM throttle characteristics. 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 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.

Each Pro Series Throttle Body is manufactured to Skunk2’s high standards and is backed by a full one-year manufacturer’s warranty.
