Manley Acura 1.6L B16A1 Exhaust Valve Kit - 28.50mm Head Dia. 102.70mm O/A Length, 0.2150in Stem

Starting with a 28.50mm head diameter and a 102.70mm overall length, these Manley Race Series exhaust valves are built for the specific needs of your 1.6L B16A1 engine. They are constructed from high-quality stainless steel, a material chosen for its ability to withstand the heat and stress found in performance applications, especially when operating under 8000 RPM. This makes them a solid option for anyone rebuilding or upgrading the top end of their engine.

Beyond the base material, these valves feature chrome stems and hard tips, which add to their longevity and resistance to wear over time. The under-head areas are swirl polished, and the combustion faces are fully machined. This attention to detail helps optimize airflow into the combustion chamber, contributing to better engine efficiency. Manley also recommends these specific valves for alcohol-fueled engines, highlighting their robust design for demanding conditions.

This kit includes the exhaust valves needed for your engine build. When working on the cylinder head, it's always a good idea to have a service manual handy for specific torque sequences and assembly procedures.
