Why a Swivel Neck Matters
K-swaps often change:
-
Engine orientation
-
Radiator placement
-
Hose routing angles
-
Clearance with intake manifolds or turbo piping
A swivel thermostat housing allows:
-
Adjustable hose direction
-
Cleaner engine bay layout
-
Reduced hose stress
-
Improved cooling system reliability
Small change. Big headache prevention.
Key Features
-
CNC-machined aluminum construction
-
Swivel/rotating neck design
-
Compatible with common K-swap radiator setups
-
Durable sealing surface
-
Designed for K20/K24 thermostat fitment
-
Corrosion-resistant finish
Translation: clean fitment without custom hose hacks.
Ideal Applications
-
K-swapped EG / EK Civics
-
DC2 Integra builds
-
RSX track projects
-
Turbo K-series setups with tight clearance
Especially useful when running custom radiators or slim fans.
Product description
MSCRP Swivel Neck Thermostat Housing for K-Series K20 K24 radiator hose k swap
The housing swivels, allowing you to position the water outlet angle before it is tightened down.
The provided custom made fitting is the same size as the oem rad hose on one end, and is threaded for an AN fitting on the other end.
This allows you to use whatever size fitting you need for custom installations. If you want to use braided hose with AN fittings, this housing will bolt on easily and with the right adapter threaded in, you’ll be all set.
The swivel neck comes pre-assembled with a quality Stant thermostat (180 deg °F) which is held in place with a ‘C’ clip.
Adjustable, set the rad hose at any angle.
Fan switch port for engine swaps.
Easily deletes heater core hoses on race cars.
Threaded water outlet for custom setups.
The kit uses a standard size thermostat that you can easily replace with anything in the (160-195 °F) degree range.

Ok guys I posted pics just in case someone wanted to get one it works great all u must do is high temp and oil resistant plummers tape all the block off ports to prevent leaks common sense tbh and u must switch out the thermostat with part # 7242-170 u can use the same gasket the thermostat comes with as well just need the the new thermostat and also a fan switch sensor for the other block off port since it doesn’t come with one part # tu197 . Or u can get it used from someone parting out a Honda works the same , again guys very happy with this part and looks dope.

Really good unit, Troy will have to remove the oem housing from the water pump. I was unlucky and got a bad thermostat. Only reason why it didn’t get a 5 star. It’s ok, you can use a Honda b series thermostat. Also the two ports for heater lines are 3/8 npt.

Nice feel and good fitment, especially for the price.

Looks nice but none of the plugs fit properly. I wrapped din teflon and even tried Honda bond but it still leaks. I returned the product .

Perfect fit but one port is slightly bigger than 3/8 plug that does not come with housing. Searched 2 days in order to find correct plug

Works great on my K24A swap. EK just make sure to switch out the thermostat and put a good amount of Honda Bond or some type of bond
