Manley Toyota 4AG Atlantic Exhaust Valve Kit - 27.50mm Head Dia. 99.75mm O/A Length, 0.2362in Stem

Manley Performance is well-known for making strong engine components for racing applications. If you're rebuilding the top end of your 1985-1989 Toyota MR2, these Manley Race Series exhaust valves are a solid option. They are built from high-quality stainless steel, which is a big step up from stock for durability, especially if you're pushing your engine hard.

These valves feature chrome stems and hard tips, adding to their wear resistance and overall lifespan. The under-head areas are swirl polished and the combustion faces are fully machined. This design helps optimize airflow into the cylinder and can contribute to more efficient combustion. They are also recommended for alcohol-fueled engines, which tells you something about their robust construction and ability to handle demanding conditions.

This kit includes exhaust valves specifically designed for your MR2's 4AG engine. Make sure to check the manufacturer's installation instructions for proper seating and valve adjustment procedures.
