  • Billet blower adapter and mounting hardware


  • 80-90MM Inlet upgrade option available for drive by cable cars. Increases performance incredibly.  Not recommended for those needing easy driving for a daily driver for stop and go constantly.  This increases power output from part throttle to full throttle tremendously.  This is a hard core upgrade that YOU must be determined to learn to drive.  This requires proper tuning if wanting to use on the street to smooth out the part throttle response to your liking. If you don’t know how to tune or do not have access to a responsive/experienced tuner, DO NOT get this for the street.



You must replace the thermostat housing with one that points downwards. Such as the Acura RSX Type S. for some vehicles; such as the Civic 8th/9th Generation.  This provides clearance for the manifold and puts heat away from the manifold.

Part needed:

Thermostat Housing Part#: 19320-PNA-003

Thermostat Part#:  19301-PNA-003

This is a direct bolt on kit for Honda Civic 8th/9th Gen and Acura TSX.

The RSX requires change on the support bar frame to clear the bypass unit. If you have a K24 swap there may be some hood webbing clearance issues you need to address.
