Fits Audi TFSI DAZA engines (2.5L). This set of 10 Ferrea Super Alloy exhaust valves is engineered for the extreme thermal environments common in high-boost Audi RS3 and TT RS builds. Featuring a 29mm head diameter, these valves provide a +1mm oversize compared to factory specifications, facilitating increased exhaust flow and improved cylinder scavenging.

Constructed from Ferrea’s proprietary Super Alloy, these valves are specifically designed to resist fatigue and deformation under the intense heat cycles of turbocharged racing applications. The 24-degree flo design optimizes gas velocity across the valve seat, while the triple-groove lock configuration ensures reliable retention during high-RPM operation.
