Product Details

Manley Severe Duty stainless steel intake valves are engine intake valves built for high-performance street, racing, and heavy-duty applications. They are designed to hold up under high cylinder pressures, high RPM, and sustained heat, and they suit performance engine builds.

Key Features:

  • Stainless steel construction: Offers good strength, heat resistance, and corrosion resistance for use in the intake port.
  • Severe duty design: Built for demanding use, including supercharged, turbocharged, and nitrous-assisted combinations.
  • Precision machined: Manley's manufacturing standards help keep the valve concentric and the dimensions consistent, so it seats and seals reliably.
  • Hardened stem and tip: Resists wear in the guide and at the keeper and rocker contact areas.
  • Performance-focused geometry: Shaped to help airflow into the cylinder and support power output.

Manley has long been a trusted name in performance engine internals, including valves, connecting rods, and pushrods. These intake valves are a solid choice for engine builders and enthusiasts who want durable, dependable valvetrain components.
