Product Details

The Manley 11127-8 Race Master exhaust valve is engineered specifically for 2001+ Acura RSX Type-S engines equipped with the K20A2 2.0L DOHC i-VTEC powerplant. These 30.0mm stainless steel performance valves are manufactured from Manley's premium Race Series alloy, designed to deliver exceptional durability and flow characteristics in high-performance applications.

Key Features:

  • 30.0mm valve diameter optimized for K20A2 16-valve cylinder heads
  • Premium Race Series stainless steel alloy construction
  • Chrome-plated stems for reduced wear and friction
  • Swirl-polished under-head surface for improved flow
  • Fully hardened valve tips for extended durability
  • Precision-machined combustion face for optimal sealing
  • Controlled margin heights and exact stem-to-seat concentricity

Built to withstand extreme exhaust gas temperatures and high-boost environments, these Race Master valves are suitable for everything from aggressive street builds to dedicated race applications producing 1000+ horsepower. The advanced metallurgy provides superior hot hardness and high-temperature strength, making these valves ideal for forced induction builds, nitrous applications, and high-RPM naturally aspirated engines where valve train reliability is critical.
