Pro X Steel Intake Valve Conversion Set

Steel Intake Valve & Spring Kits from Pro X are the perfect alternative to OEM Titanium valves. This kit includes durable steel intake valves and specially designed stronger valve springs. Simply swap out your OEM valves and springs with Pro X's kit, using the original retainers, bases, and valve seals for an easy installation.

Features:

  • Steel Valves for increased durability and less wear under extreme conditions
  • Chrome vanadium steel valve springs deal with the extra weight of the steel valves
  • Fully rebuildable with OEM retainers, bases and seals without the need of any further engine modifications
  • Nitrided valves offer high microhardness while super-smooth surface finish reduces friction between stem and guide
