Manley 90-99 Mazda Miata 1.8L (BP056) DOHC 16 Intake 33mm Stainless Race Master Valve - Single

If you're rebuilding the top end of your 1994-2005 Mazda Miata's 1.8L DOHC engine, getting the right valves is crucial for performance and reliability. These Manley Race Series intake valves are built for engines that see regular use, especially those operating under 8000 RPM. They're a solid choice for anyone looking to restore or enhance their engine's breathing capabilities.

Manley constructs these intake valves from stainless steel, which is a strong material that holds up well. The stems are chrome-plated and feature hard tips, adding extra wear resistance where it counts. You'll also notice the swirl-polished under-head area and the fully machined face; these details help optimize airflow into the combustion chamber, contributing to better efficiency. This particular valve is the Race Master style, meaning it has a straight stem, designed to fit specific racing engine configurations.

For engines running on alcohol fuels, these valves are also recommended for exhaust applications, showing their versatility and robust design. When you're putting an engine back together, using well-made components like these Manley valves helps ensure you get the performance and longevity you're after.
