TracTuff K Series Billet Thermostat Cover V1

$149.95

This is the original version with a -16 ORB female thread; all variants are created from this thermostat cover.

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. 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 is machined for -16 ORB fittings 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: 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 recommend Genuine Honda. Also, I strongly suggest measuring the space you have BEFORE ordering! The design may not work for everyone. Measurements with recommended fittings can be found below. Price includes a new Honda gasket.

This is the "All Others" Mod
