Supertech Dual Valve Spring Kit for Subaru Impreza (EJ25) - SPRK-TS1015-SU5
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Engineered for high-performance valvetrains, the Supertech SPRK-TS1015-SU5 Dual Valve Spring Kit provides the critical seat pressure and harmonic damping required for high-RPM Subaru EJ25 builds. This dual-spring configuration is specifically designed to prevent valve float, ensuring the valvetrain remains stable and responsive when using aggressive camshaft profiles or high-boost setups.
By utilizing a secondary inner spring, this kit offers superior control over valve motion compared to factory single-spring arrangements. These components are manufactured from high-tensile chrome silicon steel to ensure long-term durability and resistance to fatigue in demanding racing environments.
- Fits Subaru Impreza models equipped with the EJ25 engine.
- Design: Dual valve spring configuration for improved harmonic control.
- Function: Prevents valve float at high engine speeds.
- Material: High-quality chrome silicon steel.
- Manufacturer Part Number: SPRK-TS1015-SU5
