Show original supplier description
The Acura 16400-RK2-A01 is a genuine OEM throttle body specifically engineered for enhanced performance on Honda J30, J32, and J35 engines. This unit is based on the J37A4/5 specification and features an 80-70mm inlet-to-outlet diameter, making it a suitable upgrade for enthusiasts seeking improved airflow. However, it is crucial to note that this part is not intended for use with J32A2 engines or any other throttle-cable operated vehicles. Installation on standard J-series manifolds may require an additional adapter, with options available for both tapered and straight-through fitments. When ordering, consider the available P2R adapter options to ensure seamless integration with your specific manifold setup.
