Manley Nissan 2.0L SR20DE Exhaust Valve Kit - 30.15mm Head Dia. 102.40mm O/A Length, 0.2362in Stem

Manley Performance is well-known for building strong engine components for racing applications. If you're rebuilding the top end of your 1991-1996 or 1999-2002 Infiniti G20, or a compatible Nissan 200SX, NX, or Sentra, these Manley Race Series exhaust valves are a solid option.

These valves are constructed from stainless steel, which helps them stand up to the heat and stress of engine operation. They feature chrome stems and hard tips for improved wear resistance over time, and the under-head areas are swirl polished while the combustion faces are fully machined. This design work helps optimize airflow into the cylinder, which can lead to better combustion efficiency. They are also recommended for use in alcohol-fueled engines, which can run hotter.

This kit includes exhaust valves with a 30.15mm head diameter and a 102.40mm overall length, with a 0.2362-inch stem diameter. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
