FULL DESCRIPTION

ProX Steel Intake Valve and Spring Kit

Upgrade your engine's performance and durability with the ProX Steel Intake Valve and Spring Kit. This comprehensive kit is designed to replace your original titanium valves and springs, offering a significant improvement in lifespan. ProX's innovative steel conversion kits are engineered to last up to three times longer than OEM titanium valves.

Each kit includes high-quality steel intake valves and specially designed, stronger valve springs. The increased weight of the steel valves necessitates the use of heavier springs, which are included to ensure optimal performance and reliability. This kit is designed for a direct replacement of OEM valves and springs, allowing you to utilize your existing OEM retainers, bases, and valve seats for a straightforward installation.

Key Features:

  • Steel intake valves for enhanced durability and longevity.
  • Includes specially designed, stronger valve springs to compensate for valve weight.
  • Extends lifespan up to 3 times longer than OEM titanium valves.
  • Utilizes OEM retainers, bases, and valve seats for easy installation.
  • Direct replacement for your original valves and springs.
