Skunk2 is proud to introduce its 74mm Pro Series Throttle Body for the RSX Type-S and Pro Series Intake Manifold (part number 307-05-0310) in its signature, Black Series finish—the biggest K-series throttle body you can buy. Skunk2's Pro Series Throttle Bodies are designed to be used with OEM Acura RSX (PRB) or Skunk2 Pro Series Intake Manifolds for bolt-on horsepower and torque gains by optimizing engine airflow (other applications, including '06+ Civic Si RBC manifolds, require adapter plate). Skunk2 throttle bodies undergo an extensive design and testing process to produce a throttle body that doesnt 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. Pro Series Throttle Bodies are also compatible with OEM throttle cables, which simplifies installation. Each Skunk2 Pro Series Throttle body also features sealed bearings for smooth operation and a genuine, integrated Skunk2 badge. All necessary hardware and a new throttle body gasket are included for trouble-free installation. A larger throttle body is key to producing additional power throughout the powerband on modified engines with increased airflow demands. Skunk2's Pro Series Throttle Bodies for K-series engines feature a 74mm bore, which results in significant horsepower gains throughout the powerband on naturally aspirated applications and even more on forced induction ones.
