Supertech SPRK-TS1015-SU1 Dual Valve Spring Kit for Subaru WRX/STI 16V
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Engineered for high-performance Subaru WRX and STI 16-valve engines, the Supertech SPRK-TS1015-SU1 dual valve spring kit provides the high-RPM stability required for aggressive cam profiles and increased boost levels. These dual springs are designed to reduce harmonic resonance and prevent valve float, ensuring the valvetrain remains controlled under extreme racing conditions.
This kit replaces factory springs to offer higher seat pressure and greater lift capacity, making it a critical upgrade for builds targeting higher redlines or utilizing aftermarket camshafts. Each component is manufactured to strict tolerances to ensure consistent spring rates across the entire set.
- Part Number: SPRK-TS1015-SU1
- Engine Compatibility: Subaru 16V (EJ-series)
- Spring Type: Dual Valve Spring
- Application: High-performance street and track use
- Designed to prevent valve float at high RPMs
