2.5 TFSI/TSI 5 Cylinder Supertech Spring Kit & Retainer kit

Description Valve Spring Kit: An absolute must for anyone wishing to stretch the powerband of their engine out.. These take 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. More RPM is possible by converting to solid lifter buckets as there is plenty of spring rate here. This kit fits the 2.5 TFSI and TSI cylinder heads, any questions please drop us a mail and we will get back ASAP.
