TracTuff K Series RSX Billet Thermostat Cover

This version has been machined to remove the female thread and has a custom bent tube welded to the end to mimic the factory RSX outlet angle or pretty much any angle you might want!

No cool features, no weaknesses, no bullshit! What you see is a simple Billet Thermostat Cover that bolts to the OEM plastic housing, uses the OEM shoulder bolts, the OEM thermostat, and OEM gasket for the K20A2, K20Z1 or any other K that shares the same outlet angel. I chose the original thermostat because it is unique to this engines configuration and is related to many of customers number once concern. You wont find any sensor ports because they don't belong here and you wont find a swivel because it doesn't work for everyone anyway. 

The front -16 ORB threads have been machined off to shorten the base as well as provide a weldable surface, while the backside incorporates an OEM o-ring grove as well as features that uniquely receive the K20a2/ K20a3/ K20z1 thermostat for the most reliable function. The OEM thermostat retains the quick warm up feature of the water bypass circuit. 

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at sales@tractuff.com. If you have questions related to the configuration or options... PLEASE visit the WHATS WHAT or FAQ page.

Also, the REDESIGNED cover fits the two housing patterns scattered throughout the various models... BUT understand the new housing is not perfect. If you are using the housing from an engine code, listed above as "All Others" you need to make a modification to the aluminum water pump housing OR trim the billet cover. Yes, I said trim the brand new billet cover! Sorry.

You can choose to trim it yourself or you can have me do it at no charge. In order to run this product, you MUST use the thermostat (not included) from a 2002-2006 Acura RSX or 2002-2005 Civic Si (P/N: 19301-PNA-003). I cannot confirm aftermarket thermostat fitment and ONLY recommend Genuine Honda. Multiple swaps may benefit from this configuration, but you will need about 1.00" of free space in front of the OEM thermostat cover for this to work. The customer that ordered this... shared that the OEM RSX hose worked. If you are interested in running AN fittings, you should be choosing something from this configuration. 

This is the "All Others" Mod
