Ferrea Audi/VW BTW 29mm 5.97mm 102mm 24 Deg Flo +1mm Trpl Grv Super Alloy Exhaust Valve - Set of 8

If you're rebuilding the top end of your Audi or VW with the BTW engine, you're probably looking at replacing the exhaust valves. These Ferrea valves are built from a super alloy designed to handle the high temperatures found in the exhaust port. They're a 1mm oversize option, which can be a good choice when you're doing a full rebuild to ensure a fresh seal and optimal performance.

Ferrea makes these valves with a triple groove keeper design, which is a solid way to ensure the valve stays securely in place under high stress. The 24-degree face angle is standard for many performance applications, helping to create a good seal against the valve seat. Because these are a 1mm oversize, they're intended for engines that have been machined to accept them, often as part of a performance build or a restoration where the original valve seats might have been re-ground.

This set includes eight valves, enough for a full cylinder bank on your BTW engine. When you're putting an engine back together, using well-built components like these valves is key to a reliable and powerful result.
