Hybrid Racing 75mm PRB Throttle Body

The Hybrid Racing 75mm PRB Throttle Body is the perfect solution for your K20A2/Z1 K Swap. While the throttle body will bolt to the RSX Type-S & EP3 Civic Si intake manifold, the throttle cable bracket does not align with short ram intakes. Engineered for enhanced throttle response and increased airflow, this performance-driven upgrade provides a perfect bolt-on fit while delivering improved drivability and power gains.

Constructed from precision-machined 6061-T6 aluminum, this throttle body features a full 75mm bore for unrestricted airflow. By eliminating the bottlenecks of the stock throttle body, it allows your K-Series engine to breathe better, enhancing both horsepower and torque. Whether you're running a naturally aspirated or forced induction setup, this upgrade ensures smooth power delivery and maximum efficiency.

Direct Bolt-On Fitment for PRB Intake Manifolds

Built for Durability & Reliability

Featuring staked butterfly plate screws for added security and double-sealed roller ball bearings, this throttle body ensures smooth operation and longevity. The integrated thermal insulation gasket reduces heat transfer from the intake manifold, maintaining consistent throttle performance under extreme conditions.

Enhanced Throttle Cable Bracket & Installation

To simplify installation, the throttle cable bracket is redesigned for optimal alignment and clearance, ensuring hassle-free fitment in K Swap applications. Additionally, the dual stainless-steel throttle return springs provide extra safety and longevity, preventing premature wear.
