Supertech Honda B16A/B18C Inconel Exhaust Valve - +0.5mm Oversize - Set of 8

Made from Inconel, a high-nickel alloy known for its extreme heat resistance, these Supertech exhaust valves are built to handle the demanding conditions found in high-performance Honda B16A and B18C engines. The material choice is critical here; Inconel can withstand temperatures that would cause standard steel valves to warp or fail, making it a solid option for engines pushed beyond stock limits. This set includes eight valves, each measuring 0.5mm oversize, which is a common choice when rebuilding or modifying cylinder heads to ensure a fresh seal and optimal performance.

When you're rebuilding the top end of a B-series engine, especially if you're aiming for more power or durability under stress, the exhaust valves are a key component to get right. The Inconel material offers improved strength and resistance to thermal fatigue compared to conventional alloys. The +0.5mm oversize dimension means these valves are slightly larger than stock, which can help compensate for wear on the valve seats or allow for a more precise fit during a performance rebuild. This attention to material and sizing helps ensure a well-sealed combustion chamber and consistent performance.

This set of eight valves is designed to replace all the exhaust valves in your Honda B16A or B18C engine. Ensure you have the correct tools and procedures for valve installation, as proper seating and valve spring setup are crucial for engine health. If you're working on a performance build or a thorough engine overhaul, these Inconel valves are a well-built choice for reliability and performance.
