Ferrea Ford Zetec ZX3 33mm 5.5mm 25 Deg S-Flo +1mm Competition Plus Intake Valve - Set of 8

Ferrea is well-known for making high-performance engine components, and their Competition Plus valves are a popular choice for builders looking to get more out of their engines. This set of eight intake valves is specifically designed for Ford Zetec ZX3 engines, featuring a 33mm head diameter and a +1mm oversized design. The 25-degree seat angle and S-Flo technology help improve airflow into the combustion chamber, which can lead to better throttle response and overall power.

These valves are constructed from strong, durable materials to withstand the demands of performance applications. The +1mm sizing means they are slightly larger than stock, allowing for increased airflow when used with matching porting and camshafts. This is a solid option if you're rebuilding the top end of your Ford Zetec ZX3 and want to optimize its breathing capabilities.
