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 kit is designed as a high-quality replacement for your original equipment, offering a significant improvement in lifespan compared to standard titanium valves.
ProX is known for its innovative conversion kits, and this steel intake valve set exemplifies their commitment to quality and longevity. The kit includes a robust steel intake valve and specially designed, stronger valve springs. The heavier steel valve requires a stronger spring to ensure optimal performance and prevent valve float.
Installation is straightforward as this kit is engineered to directly replace OEM valves and springs. You can use your original retainers, bases, and valve seats, making the upgrade process seamless.
Key Features:
- Extends lifespan up to three times longer than OEM titanium valves.
- Includes a high-quality steel intake valve.
- Comes with specially designed, stronger valve springs to match the heavier valve.
- Direct replacement for OEM valves and springs.
- Utilizes existing OEM retainers, bases, and valve seats.
- Constructed with durable materials for enhanced reliability.
