【Fitment】Tektall Aluminum Intake Manifold Coolant Adapter fits for K24A2 K24Z3 K24Z7 Engine.
【Product Introduction】 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 isnt on K20 intake manifolds. We have designed the adapter to work with all K24 heads including the K24Z-Series (R40) heads.
Tektall Aluminum Intake Manifold Coolant Adapter 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 the adapter. The adapter also features a 1/8 NPT port for a coolant temp sensor commonly used in swap cars. The Intake Manifold Adapter can be installed either using our spring loaded tab or by tapping the head.
When using the spring loaded tab when the adapter isnt 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.
【Installation tools required】 Drill 1/4 or 6.5mm drill bit,13/64 or 5mm drill bit,M6x1.0 tap (Standard and bottoming). NOTE：The detailed installation process is in the product description.

Install Procedure

Installation tools required Drill 1/4 or 6.5mm drill bit 13/64 or 5mm drill bit M6x1.0 tap (Standard and bottoming).

Ensure when installing that the adapter gets mounted directly to the head (Do Not Install A Gasket Between The Head and The Adapter). 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 use a 5mm or 13/64 drill bit to drill the head to a depth of at least 11mm (the depth of the bolt) but shouldn’t need more than 14mm. 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. Use a M6x1.0 tap and lube and do it slowly. 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 too far.

Unless you have access to tools and real hardware store (not home improvement), spend the extra money and buy the K-Tuned adapter. The mating surface to the head around the mounting holes aren't flat and needed sanding. Both the 90 degree fitting and hose nipple use straight threads and o-rings. However there is no groove for the o-rings to seat into and they deform when tension is applied. I removed the o-rings and used sealant and crush washers to seal the threaded portions. The K-Tuned adapter uses pipe threads that would ensure a long lasting leak free installation. You get what you pay for!
