T7Design Honda K20 Front & Rear Thermostat Housings Bundle (68c)
£360.00 £300.00
To £375.84 £313.20
The T7Design Honda K20 Front & Rear Thermostat Housings Low Temperature Bundle includes:
K20 Swivel Neck Thermostat Housing - Hard Anodised Black
T7design Honda K20 swivel neck thermostat housing is fully machined from 6062-T6 billet Aluminium and is available with either a 32mm or AN16 hose connector. The outlet angle is the same as OEM and is within 10mm offset from the mounting flange face to ensure all OEM and aftermarket hoses fit perfectly. The housing also incorporates an M22 x 1.5 hole for radiator fan switches – perfect for k-swaps.
Using top of the range metrology grade laser scanning and 3D printing equipment we can ensure the products are designed for perfect operation and fitment. For example, our 3-bolt mounting flange aligns perfectly with the outside profile of the OE plastic mounting face.
Our thermostat housing is the only aftermarket housing you should run on your vehicle, unlike the competition we use the OEM dual plunger thermostat that ensures operation exactly like Honda intended. Other units actually reduce the efficiency of your cooling system by not using a dual plunger thermostat design which is there to gradually reduce and stop flow through the bypass port when things get hot. Also, plain steel is not used anywhere in our housings, this ensures that with our units you will not face orange rust covering all surfaces inside your engine and radiator, further reducing the efficiency of your cooling system.
The unit is available with or without a radiator fan switch, if you chose without then it will be supplied with a custom made billet Aluminium M22 blanking plug and O-ring. The fan switch supplied is manufactured in the EU and are rated to over 1 million operations, we do not substitute on quality with our products! The fan switch turns on at 95c and off at 86c.
T7Design Honda K20 Billet Thermostat Housing Rear
The OEM version is exact replacement for Honda part number: 19320-PNA-003
We've enhanced our OEM replacement thermostat housing rear to accommodate applications utilizing aftermarket heater systems, where the original formed metal tube may not be suitable. The modification involves replacing the original counter-bored hole for the push-fit heater hose with an ORB10 threaded hole. This adjustment provides users with the flexibility to adapt any heater hose to the housing. As part of the kit, we include an ORB10 port plug for instances where the heater hose is not utilized. Additionally, we include an ORB10 to AN10 male adapter for use of AN fittings for the heater circuit.
Introducing our full CNC machined billet K20 Thermostat Housing Rear half, this is a beautiful crafted like for like replacement of the original Honda part: 19320-PNA-003. As the original plastic housings age, they become susceptible to cracking, distortion, and leaks due to the effects of time and numerous heat cycles. Our housing offers a durable alternative, seamlessly compatible with all original hoses, including the thermostat bypass, metal heater hose, and either an original thermostat or our own billet version for a comprehensive upgrade. Maintaining precise alignment with OEM specifications, including mounting points, hose locations, and thermostat mounting faces, this housing functions identically to the original piece, but without the drawbacks of the original.
To design this component, we 3D laser scanned a brand new, pristine, original housing to capture precise OEM dimensions, we then reverse engineered the part to obtain datums, critical measurements and features prior to drawing the part to make it suitable for a completely different manufacturing process; 3D CNC machining. This preliminary information guided us in transforming the design to align with the requirements of an entirely distinct manufacturing method—3D CNC machining. Extensive effort was dedicated to refining the design, ensuring that every aspect could be seamlessly machined while preserving each key feature in its original position. This meticulous approach was undertaken to guarantee a flawless fit, finish, and function of the final product. Please be aware that the production of this part from solid billet necessitates a significant amount of machine time.
