【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.
