Product Details

Manley Performance is known for making well-built engine components for racing applications, and these Race Master intake valves are a prime example. If you're rebuilding the top end of your 2008-2014 Scion xB, or a compatible Toyota Camry or Solara, these 34mm stainless steel valves are designed to handle the demands of performance engines.

These valves are constructed from high-quality stainless steel, giving them solid durability. They feature chrome stems and hard tips to resist wear over time, and the swirl-polished under-head areas along with fully machined combustion faces help optimize airflow into the cylinders. Manley offers these in a Race Master (straight stem) shape, which is what you'll find in this part number, making them a good choice for engines that operate under 8000 RPM.

These are specifically intake valves, and they are also recommended for use in alcohol-fueled engines where exhaust valves need to be particularly robust. If you're looking for improved airflow and long-lasting performance for your engine build, these Manley valves are a solid option.
