Precision Ferrea Comp Plus Exhaust Valves for BMW S55

The BMW S55 engine is a powerhouse, but it requires a robust valvetrain to handle the stresses of high-boost tuning. This set of 12 Ferrea Comp Plus Exhaust Valves is the ultimate solution for enthusiasts looking to prevent valve failure. These valves are manufactured using high-strength alloys that offer exceptional heat resistance and durability, ensuring your S55 stays reliable under heavy load.

  • Stem Diameter: 5.96mm
  • Overall Length: 112.83mm
  • Seat Angle: 21 Degrees
  • Groove Type: Triple Groove
