Supertech Honda H22A1/H22A4 Inconel Exhaust Valve - +1mm Oversize - Set of 8

This set includes eight Supertech Inconel exhaust valves, each measuring 1mm oversize for your Honda H22A1 or H22A4 engine. These valves are crucial components for your engine's breathing system, controlling the flow of air and fuel into the cylinders and exhaust gases out. When rebuilding or upgrading your engine, especially if you're pushing performance limits, the right valves make a significant difference in how efficiently your engine can operate.

Crafted from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme temperatures, these valves are built to handle the demanding conditions inside a high-performance engine. The +1mm oversize design allows for a larger valve head diameter, which can improve airflow and potentially increase power output, especially when paired with other engine modifications. This material choice means they can withstand the heat and stress associated with aggressive driving or boosted applications, offering a well-built solution for durability.

If you're working on a performance build for your H22A1 or H22A4, these valves are a solid option. They are designed as direct replacements for your stock valves, but remember that installing oversize valves often requires matching cylinder head porting to take full advantage of the increased flow potential. Always consult your engine build guide or a trusted mechanic for specific installation recommendations.
