Ferrea Porsche 996TT 3.6L 38mm 5.97mm 19 Deg S-Flo +1mm Sgl Rad Grv Comp Plus Int Valve - Set of 12

If you're rebuilding the top end of your Porsche 996TT 3.6L engine, you'll want to make sure your intake valves can handle the demands of performance driving. These Ferrea Comp Plus intake valves are built for that purpose. They feature a 38mm head diameter and are a +1mm oversized design, which can help improve airflow into the combustion chamber when paired with appropriate cylinder head work.

Ferrea uses a high-strength, high-chrome, nickel-based alloy for these valves, which is known for its durability and resistance to high temperatures. The S-Flo design is intended to improve airflow characteristics, and the single radius groove helps with valve spring compatibility. These valves are designed to be a direct replacement for your stock valves, fitting the 5.97mm stem size and 19-degree seat angle.

This set includes 12 valves, enough for your entire engine. When installing, ensure your valve guides and seats are in good condition to match the new valve dimensions and ensure proper sealing.
