Function: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
Adapters: Intake Manifold Adapter Recirculation Fitting designed adapters to fit all K24 heads, including the K24Z series (R40) heads
Installation Note: Make sure the K24 Intake Manifold Adapter is mounted directly to the head when installing (do not install a washer between the head and the adapter). First use a 6.5 mm or ¼ drill bit to complete the blind holes in the adapter. Then you want to install the manifold and adapter in the head. This will ensure that you position the holes correctly.The Intake Manifold Adapter can be installed either using our spring loaded tab or by tapping the head
Additional Use: This Intake Manifold Adapter Recirculation Fitting can also be used to install a K20 manifold or cut RBC manifold on a Gen 9 si, as the water bypass is slightly different and you do 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
Features:About this Intake Manifold Adapter Recirculation Fitting,we use good gasket because it provides a strong seal and there is no possibility of leakage when using spring loaded tabs with no pressure on the adapter
