Show original supplier description

The K-Tuned 70mm Cast Throttle Body provides an accessible performance upgrade by allowing more air into your engine, potentially increasing horsepower. Engineered for a direct fit with PRB/PRC and RBC/RRC intake manifolds, this unit features a 70mm bore. It retains essential provisions for Throttle Position Sensor (TPS), Idle Air Control Valve (IACV), Manifold Absolute Pressure (MAP), and Evaporative Emission Control (EVAP). Installation is simplified as all necessary hardware, a gasket, and a throttle bracket are included. The throttle wheel is designed in an OEM style to help manage costs, while a stiffer spring is incorporated to provide a more responsive 'snap' when closing. This throttle body is designed to use the sensor from a 2002 Acura RSX Type S. Note that the stock RSX/EP3 throttle cable will likely not be the correct length, and a K-Tuned Throttle Cable is recommended. Applications for this throttle body include the 2002-2006 Acura RSX, 2004-2008 Acura TSX, and 2012-2015 Honda Civic Si. It requires engine management, such as K-Pro, due to the inclusion of an EVAP port. The IACV can be plugged using the supplied 1/8NPT plugs if needed.
