Kelford Beehive Valve Spring, Titanium Retainer and Seat Kit - Audi RS3 2.5 TFSI (EA855 DAZA)

This Kelford beehive valve spring kit with titanium retainers and spring seats suits the Audi RS3 with the 2.5L EA855 DAZA five-cylinder engine. It is built for high boost and high RPM use, with a high spring frequency that controls spring surge at high revs and about 30 percent more seat pressure than the factory spring. The springs are wound in the USA by PAC from premium spring steel, heat treated and nano peened to extend fatigue life. This kit is the required spring upgrade for the Kelford Stage 1 and Stage 2 RS3 camshafts, and spring seats are supplied for the intake side only.
