TracTuff K Series DC5/ EP3 Billet Thermostat Cover

Description

This version has a bent tube welded to the billet thermostat cover to closely mimic the factory RSX/ EP3 outlet angle.

The Billet Thermostat Cover natively bolts to the OEM K20A, K20A2, K20A3, and K20Z1 plastic housing(s) using the original shoulder bolts, OEM thermostat, and OEM gasket. The billet cover will also fit all other K series thermostat housings found on “all other” engine codes not mentioned above by modifying one of the lower mounting tabs (see picture below).

NOTE: The billet thermostat cover does not include a thermostat. To run this product, you MUST use a 2002-2006 Acura RSX or 2002-2005 Civic Si (P/N: 19301-PNA-003) thermostat. I ONLY recommend Genuine Honda.

“All Others” modification shown below.

Multiple swaps may benefit from this configuration; however, my thermostat cover is slightly taller, and you will need approximately 1.00″ of additional space in front of your current OEM thermostat cover for this to fit. Customers who have ordered the standard hose configuration have shared that the OEM RSX lower hose has worked when the radiator outlet is in the same location as the RSX outlet.

If you are choosing the AN connection option… I strongly recommend that you either have a dual pass type radiator where the outlet has been moved to the end of the driver’s side tank, or be prepared to move your current radiator outlet as far away as possible. The distance from the radiator outlet and the thermostat cover is too close, and trying to reproduce the factory rubber hose’s odd short and twisted shape is impossible to do cleanly. Shame on the radiator companies who make an AN or interchangeable inlet with the RSX/ EP3/ CL9 position!
