Ferrea Exhaust Valves 30.9mm 5.96mm 103.92mm 26 Degree Flow +1mm Groove Compatible with Audi APB VW 1.8T 20V Set of 8

Designed for precision and durability, these valves optimize airflow and combustion efficiency within the cylinder head. The 30.9mm diameter intake valves and 26-degree seat angle are engineered to enhance valve seating and airflow dynamics, contributing to improved engine breathing and performance consistency under high RPM conditions.

Constructed from high-grade materials, each valve features a 5.96mm stem diameter and a 103.92mm overall length, ensuring compatibility with specified cylinder heads while maintaining the structural integrity required for demanding engine environments. The +1mm valve length on the exhaust side allows for enhanced sealing and improved gas flow characteristics.

The groove design on the valve stems facilitates precise valve spring retention, reducing the risk of valve float and ensuring reliable operation at elevated engine speeds. This design consideration supports sustained performance and longevity even under rigorous operating conditions.

• Enhanced airflow: Optimized valve diameter and seat angle improve volumetric efficiency.
