This set includes ten Ferrea Competition Plus intake valves, specifically designed for Audi TFSI DAZA engines.

Ferrea uses high-grade materials to construct these valves, ensuring they can handle the demands of high-performance engines. The S-Flo design is intended to promote better gas flow into the cylinder, while the +1mm oversized head can help increase airflow potential. The triple groove keeper design is a well-known feature for securing the valve spring effectively under high stress.

If you're rebuilding the top end of your Audi TFSI DAZA engine and looking for improved airflow, these Ferrea valves are a solid option. They are designed to be a direct replacement for the stock valves, but with performance enhancements.
