Ferrea Ford Zetec ZX3 28.96mm 6.012mm 97.16mm 25 Deg Flo +1mm Super Alloy Exhaust Valve - Set of 8

If you're rebuilding the top end of your Ford Zetec ZX3 engine, these Ferrea Super Alloy Exhaust Valves are a solid choice. This set includes eight exhaust valves, each measuring 28.96mm in diameter with a 6.012mm stem and a total length of 97.16mm. They feature a 25-degree Flo +1mm design, meaning they are 1mm larger in diameter than stock to help improve airflow into the cylinder.

Ferrea uses a special Super Alloy material for these valves, which is known for its strength and resistance to high temperatures and stresses found in performance engine builds. This well-built construction helps ensure reliable performance and longevity, especially when you're pushing your engine harder. The +1mm sizing is a common upgrade for Zetec engines looking for improved breathing and a bit more power.
