Show original supplier description
The Skunk2 Alpha Series 70mm Throttle Body is engineered to deliver increased airflow and power throughout the entire powerband for modified engines. This throttle body is a direct replacement for D, B, H, and F-series Honda engines, offering a significant upgrade over stock. Constructed from precision die-cast aluminum with a fine shot-blasted surface finish, this throttle body boasts a 70mm bore. It utilizes a precision-machined brass throttle plate and sealed ball bearings for exceptionally smooth operation, even in aggressive naturally aspirated and forced induction applications. The oversized bore is honed for optimal airflow. Compatibility with the OEM throttle cable is maintained, and the unit includes idle adjustment screws for precise tuning, along with a new throttle body gasket and necessary hardware. This Skunk2 throttle body is designed to be compatible with Skunk2's Pro Series Intake Manifolds, as well as OEM and other aftermarket intake manifolds, facilitating a bolt-on installation. It fits a wide range of Honda and Acura models, including the CR-V (1997-2001), CRX (1988-1991), Del Sol (1993-1997), Accord (1990-2002), Civic (1988-2000), Integra (1990-2001), and Prelude (1992-2001).
