If you're rebuilding the top end of your Porsche M44.X engine, you'll want to make sure your new valves can handle the demands. These Ferrea Comp Plus intake valves are built to be a strong replacement for your stock valves, helping to ensure proper sealing and airflow into your cylinders. They are designed with a +1mm oversized head diameter, measuring 46mm, which can help improve airflow into the combustion chamber when paired with appropriate porting. The 8.98mm stem diameter and 111.6mm overall length are designed to fit your M44 engine's valve guides and retainers.

Ferrea uses a triple groove keeper design on these valves, which offers a secure fit for your valve springs and retainers. The S-Flo (Swirl Flow) design is intended to help improve airflow characteristics. These valves are made from durable materials to withstand the heat and stress of engine operation. This set includes four intake valves, ready for installation in your M44 engine.
