DESCRIPTION
Upgrade your valve train with the Supertech Dual Valve Spring Kit for the VW/Audi 1.8T 20V 4cyl. SPRK-AUDI18T-DR is designed for the VW/Audi 1.8T 20V 4cyl and is sold as a complete kit.
Supertech Dual Valve Springs feature an inner and outer spring nested together, dramatically increasing the installed spring pressure and surge resistance needed for aggressive cam profiles and high-RPM operation. The dual spring design reduces valve float and improves valve control at the top of the RPM range, making them the go-to choice for forced induction builds, race engines, and any application pushing past factory cam specs.
Supertech Dual Valve Spring Kit Features:
- Matched inner and outer spring pair for optimal performance
- Increased installed seat pressure over OE single springs
- Eliminates valve float at high RPM
- Required for aggressive aftermarket cam profiles
- Precision wound for consistent spring rate across the set
- Direct fitment for listed engine applications
