Supertech Valve Spring & Titanium Retainer Set, Volkswagen FSI & TSI 2.0T Engines

Product Description:

The Supertech Performance Valve Spring & Retainer Set is designed for those looking to improve the powerband of their 2.0T FSI or TSI engine past 7,500 RPM, safely. This kit takes a two pronged approach by increasing the spring rates meanwhile reducing the mass of the retainer, by using titanium. The use of titanium provides an adequate fatigue life to be acceptable for all but the highest mileage street use.

These will allow usage up to 8,000 RPM although we have used them for occasional use to 8,500 RPM on hydraulic lifters. More RPM is possible by converting to solid lifter buckets as there is plenty of spring rate here.

Features:

• Performance Valve Springs Made with Premium Superclean Chrome Silicon Vanadium Steel Alloy for Higher Performance and Durability
• Increased Spring Rate to Stretch the Powerband of the 2.0T Engine Out Past 7,500 RPM, Safely.
  • Note: Above 7500RPM, Factory Rods Should Be Updated Unless Specified by the Tuner to be OK.
• 6AL4V Grade Titanium Retainers for Reduced Mass, Helping to Prevent Valve Float
• Allows up to 8,000 RPM (Occasional Use to 8,500 RPM on Hydraulic Lifters)
