TracTuff K Series “Custom” Billet Thermostat Cover

Description

This version has been machined to remove the female thread and has a bent tube welded to the end to create an outlet angle specific to your needs (see end of description).

The Billet Thermostat Cover bolts to the OEM plastic housing using original shoulder bolts, OEM thermostat, and OEM gasket for the K20A, K20A2, K20A3, K20Z1, or any other K variant that shares the same plastic cover and thermostat. I chose to design the cover to hold the original thermostat rather than a generic alternative because I felt it was the main contributor to cooling system problems, where the original cover was ditched.

You won’t find any sensor ports on the cover because they don’t belong here. You won’t find a swivel feature because it doesn’t work for everyone anyway.

NOTE: If you are interested in a specific design that varies from this, please email us at sales@tractuff.com. 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.

Multiple swaps may benefit from this configuration; however, you will need to verify your clearances. Do NOT choose the low-profile bend for 7, 8, or 9 o’clock position(s). If you have A/C, I do not recommend anything beyond 8 o’clock and with any angle beyond 50°. If you are interested in running AN fittings, it might make more sense to run the V2 Cover and use the hose fitting to make the necessary bend.

I recommend you sit down in front of your engine and get eye level with the thermostat housing, as shown in the image below, and note where you want the inlet positioned. What is shown is 9 o’clock.

Most customers choose the basic angle of 90° (straight forward for RWD swaps) because it is easy to understand and communicate, but you have control over this as well. I can offer everything from 10° to 90° in 10° increments. If you want a straight out connection, purchase the V2 Thermostat Cover.
