• TracTuff K Series RWD Billet Thermostat Cover

    $199.95

    Originally offered as a configuration option but due to customers complaining that the options were confusing, I have decided to give the common RWD selection its own spot. 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 pretty much any RWD k swap. 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. What you do get is, a straight forward, refreshing design that allows the end-user to chose whichever fitting he/ she needs to plumb the lower hose.


    Machined from US milled 6061 aluminum; the flange incorporates an OEM o-ring grove and the front (originally threaded for -16 ORB) has been machined to remove the material beyond the thermostats locating pin, reducing the overall length and welding a straight section of 1-1/4" tube or a -16 male flare. The Billet Thermostat Cover uniquely receives the K20a2/ K20a3/ k20z1 thermostat for the most reliable function and retains the quick warm up feature of the water bypass circuit. 

    NOTE: The TracTuff K Series Billet Thermostat Cover is designed to be a direct replacement for the 2002-2006 Acura RSX or 2002-2005 Civic Si thermostat cover. In order to run this product, you MUST use the thermostat (not included) and thermostat case (back-half that bolts to the water pump housing (P/N 19320-PNA-003)) from a 2002-2006 Acura RSX or 2002-2005 Civic Si. The water pump housing bolt pattern is common between all the k series engines I have touched, so if you do not have the correct thermostat case to use my cover... you can simply swap it out. The S2000 and Miata k swap benefits from this configuration the most, but as more and more chassis are being k swapped, I imagine others will as well. I strongly suggest measuring the space you have BEFORE ordering any configuration! Some RWD swaps may have enough room to use an unmodified cover with a screw in fitting and save a few bucks.
