You must replace the thermostat housing with one that points downwards. Such as the Acura RSX Type S. This does two things. Provides clearance for the massive manifold, puts additional heat away from the manifold.

Thermostat Housing Part#: 19320-PNA-003

Thermostat Part#:  19301-PNA-003


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

The RSX requires a small change on the support bar frame to clear the bypass unit.
