It combines an 80mm single-blade opening with a 3.5-inch inlet outside diameter and provisions for the factory RB20\/RB25DET throttle position sensor. Ships fast across Canada and the US.\u003c\/p\u003e\u003cdiv style=\"border-left: 4px solid #333; padding: 10px 16px; margin-bottom: 16px; background: #f9f9f9;\"\u003e\n\u003cstrong\u003eDoes not bolt onto the factory RB20\/RB25DET manifold:\u003c\/strong\u003e This throttle body uses a Q45-style four-bolt pattern measuring 78 × 78mm center-to-center. Factory manifolds have a smaller mounting pattern. A compatible Q45-pattern intake manifold is required.

This RB-specific unit is not the separate CXRacing SR20DET throttle body. Q45-style refers to the manifold mounting pattern and does not establish direct replacement fitment for a Q45 vehicle.\u003c\/p\u003e\u003cp\u003eThis listing is for the throttle body with the described cable-adapter arrangement. A new TPS sensor, intake manifold, throttle cable, intake coupler, gasket and mounting fasteners are not promised as included.

Verify that the throttle opens fully and returns freely to the closed position without binding, and that the cable and return mechanism operate correctly before starting the engine.\u003c\/p\u003e\u003cp\u003eCheck sealing, TPS adjustment and idle operation after installation. Engine-management calibration may need review for the modified intake setup. No horsepower increase, airflow percentage or universal throttle-response improvement is guaranteed.\u003c\/p\u003e\u003cp\u003eCXRacing markets this product for competition vehicles.
