K-Tuned has the solution to your lower rad hose problems. Some of the motors we have received came with an OEM plastic water neck broken. Until now, you could only order a replacement part from Honda/Acura. Problem is they only sell the housing complete with the thermostat, which is pretty expensive and it doesn’t provide any real benefits. If your housing isn’t broken then you still have to get the right hose, with the right angles and mate it to the radiator. After that, you have to figure ...

The K24 Intake Manifold Adapter is a simple and easy way to install K20 style manifold on K24 heads.

We have designed the adapter to work with all K24 heads including the K24Z-Series (R40) heads. This can also be used to install K20 manifolds or cut RBC manifolds on 9th gen Civic si as the water bypass is slightly different and you will not need an intake manifold adapter when using...

Applications: K20A, K20A2, K20A3, K20Z1, K24A1 cylinder heads. We've taken input from guys running big turbo setups on this one. The integrated filler now clears up more room for big turbo setups. The filler neck comes off the top of the housing and can be used to relocate the radiator cap to a higher point on the engine itself. The new location is the highest point of the cooling system and allows air pockets to easily escape during the coolant bleeding process. The Filler Neck is also avail...
