Supertech Honda B16A 29x5.45x102mm +1mm OS Dish Inconel Exhaust Racing Valve - Set of 8

These Supertech exhaust valves are made from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme heat. This makes them a solid choice for high-performance Honda B16A engines where exhaust temperatures can get very high. Each valve measures 29mm in diameter with a 5.45mm stem and a 102mm overall length, and this set is specifically designed to be 1mm oversize, which can help improve sealing and performance when rebuilding or upgrading your engine's top end.

The dish design on these valves is intended to optimize combustion chamber volume and airflow. Because Inconel can withstand higher temperatures than standard stainless steel, these valves are well-suited for racing applications or heavily modified street engines that see frequent high-RPM use. Installing these valves is part of a larger engine rebuild process, so ensure you have the necessary tools and knowledge, or consult a professional mechanic for installation.
