Supertech Ford Focus Zetec 2.0L Inconel Exhaust Valve - +2mm Oversize - Set of 8

Crafted from Inconel, a high-nickel alloy known for its exceptional heat and corrosion resistance, these Supertech exhaust valves are built to handle the demands of performance-oriented Ford Focus Zetec 2.0L engines. This set includes eight valves, each measuring 2mm larger than stock, which can help improve airflow into the combustion chamber when paired with appropriate cylinder head work. The Inconel material is particularly beneficial for exhaust valves, as it can withstand the extreme temperatures and pressures found in the exhaust port, helping to prevent valve distortion or failure under hard use.

Choosing Inconel for exhaust valves is a smart move for anyone rebuilding or significantly modifying their Zetec 2.0L engine. This alloy maintains its strength at high temperatures, which is crucial for longevity and consistent performance. The +2mm oversize design is a common modification for enthusiasts looking to maximize cylinder head flow, often done in conjunction with porting and polishing the cylinder head. These valves are well-built and designed to be a direct replacement for your factory valves, though professional installation is recommended to ensure proper seating and valve guide compatibility.
