Designed for the extreme thermal environments of high-boost Subaru EJ20 engines, this set of eight Ferrea Super Alloy exhaust valves provides the durability and heat resistance required for competition use. These +1mm oversize valves feature a 33mm head diameter and a proprietary Super Alloy construction that maintains structural integrity under intense exhaust gas temperatures where standard stainless steel might fail.

  • Manufacturer Part Number: F1519P
  • Fitment: Subaru EJ20
  • Quantity: Set of 8 Valves
  • Material: High-Temperature Super Alloy
  • Head Diameter: 33.00mm (+1mm Oversize)
