The TracTuff K Series Billet Thermostat Cover is NEWLY REDESIGNED to fit all k series housings!!!
A copy of the RWD thermostat cover but with options not listed on the original offering that are unique to the NSX swap. 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 NSX k swap.The original thermostat was retained 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 1-1/2" tube or a -20 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 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 still MUST use the thermostat (not included) from a 2002-2006 Acura RSX or 2002-2005 Civic Si. Multiple swaps may benefit from this configuration. If you are interested in running AN fittings, you should be choosing something from this configuration.
