Ferrea Audi 1.8T 20V/2.7T 30V 27.9mm 5.97mm +1mm Comp Plus Int Valve - Single (Drop Ship Only)

This is a single Ferrea Comp Plus intake valve, specifically made for Audi 1.8T 20V and 2.7T 30V engines. It measures 27.9mm in diameter with a 5.97mm stem, and it's a +1mm oversized valve, meaning it's slightly larger than the stock size to help improve airflow into the cylinder.

Ferrea valves are known for being well-built, and the Comp Plus line uses a specific heat-treating process and a unique swirl-polishing technique on the intake side. This helps make the valve stronger and improves airflow, which can lead to better engine performance. The +1mm sizing is a common upgrade for tuners looking to get a bit more out of their engine, especially when rebuilding or modifying the cylinder head.

This is a single valve, so be sure to order the correct quantity for your engine build. It's a good idea to check your engine's specific requirements to confirm if this oversized valve is the right choice for your application.
