Your cart is empty. INSATLLATION INSTRUCTION:
Begin by using the 6.5mm or ¼ drill bit to finish the blind hole in the adapter. You then want to install the manifold and adapter on the head. This will ensure you are properly positioning the hole. Once you have marked where you want to drill remove the manifold and adapter. Place tape or plug the holes on the head for intake and coolant to prevent anything from getting inside. You will be tapping at least 11mm depth (the depth of the bolt) but shouldn’t need more than 14mm of depth. You can apply tape on the drill bit to ensure not to drill too deep. Once you drill the hole you will run your tap. Be careful not to tap too deep. You can start the thread with a standard tap but you should finish it using a bottoming tap. This will allow the bolt to use most of the tapped hole. Slowly start to tap the head and check fitment of your adapter often. You want the adapter to hold snug but not tap the hole to far.
The Intake Manifold Adapter can be installed either using our spring loaded tab or by tapping the head. We use original Bond or similar gasket maker as it provides a strong seal and when using the spring loaded tab when the adapter isn’t under pressure there will be no chance of leak. The spring loaded tab holds the adapter down with constant spring pressure to ensure a tight fit and seal. The other option is using the provided blind hole you can easily tap the head for the second hole. Tapping the head will require a 6.5mm drill bit (to finish the blind hole in the adapter), 5mm drill bit (to drill the head), and M6x1.0 Tap.
The K24 Intake Manifold Adapter is a simple and easy way to install K20 style manifold on K24 heads. The recirculation fitting on K24s is typically part of the intake manifold which isn’t on K20 intake manifolds. 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

I installed this on my K24a to install a type-s intake and I'm happy that it doesn't leak. there's no more coolant outlet for the throttle body but honestly I might just fully delete that part and get a bigger throttle body.

When you install this part use liquid gasket between the engine and adapter so it does not leak coolant

Doesnt line up with felpro gasket. Also the pqy label is crooked which doesnt look very good when installed. Will have to modify it to work.

The port on the back side doesn't have an O-ring so you will need to use silicone, I used permatex ultra grey. The fittings will smoosh the installed O-rings out when you attempt to clock the fitting to point at the thermostat housing and tighten the hose barb. I also opened up the port with an 7/16" drill bit to gain a little extra flow.

So far the fit is perfect and it's exactly what I needed to fit my prb manifold on my k24
