20 Best Cathedral Port Intake (2022 Updated)

A cathedral port intake is an intake manifold designed for high-performance engines that uses a “cathedral” port to connect the cylinder heads to the plenum. The port is named for its cathedral-like shape, which is created by the way the intake manifold is cast.

The cathedral port intake is a popular choice for high-performance applications because it offers excellent airflow and can be very efficient. However, it can be difficult to design and manufacture a cathedral port intake that meets all of the necessary performance criteria.

Conclusion

The conclusion of the cathedral port intake is that it is a very efficient way to intake air into the engine. It provides a lot of airflow and helps to improve the performance of the engine. It is also a very good way to keep the engine cool and helps to improve the life of the engine.
