What is the main benefit of the stainless steel construction?

Stainless steel construction offers good durability for the valves. Combined with chrome stems and hard tips, these valves are built to resist wear and last longer in demanding engine conditions.

Are these valves suitable for all engine builds?

These Race Master valves are specifically designed for engines operating under 8000 RPM. They are also recommended for exhaust valves in alcohol engines, but this set is for intake on gasoline engines.

What does 'swirl polished' and 'fully machined' mean for these valves?

Swirl polishing on the under-head areas and machining on the combustion faces are done to improve airflow into the cylinder. This can contribute to better combustion efficiency and overall engine performance.

About this part

Product Details

Manley Performance is well-known for building robust engine components for racing applications. If you're rebuilding the top end of your 2008-2014 Scion xB, these Race Master intake valves are a solid option. They are designed for engines that operate under 8000 RPM, making them suitable for demanding street or track use.

These intake valves are constructed from stainless steel, which offers good durability. They feature chrome stems and hard tips to resist wear over time, and the under-head areas are swirl polished while the combustion faces are fully machined. This machining helps optimize airflow into the combustion chamber, which can lead to improved engine efficiency.

This particular set is for the intake side and features a straight stem design, known as Race Master. Manley also offers Race Flo shapes for different engine builds. These valves are also recommended for exhaust use in alcohol-fueled engines, though this set is for intake on gasoline engines.
