    • Inner diameter of the inner spring (exhaust): 15.50mm
    • Outer diameter of the outer spring (exhaust): 29.10mm
    • Inner diameter of the outer spring (exhaust): 21.90mm
    • Seat pressure / installed length: 36.29kg @ 33.20mm
    • Seat pressure at lift: 90.72kg @ 11.00mm
    • Max lift: 13.70mm
    • Supplied with 20 retainers and 8 spring seats (exhaust)
    • Reference: SPRK-AUDI18T

    SUPERTECH valve springs are made from a high grade chrome silicon vanadium steel alloy. That alloy delivers higher performance and reliability, above all at high revs, and it has a better structural memory. SUPERTECH performance valve springs are computer designed so that harmonics stay under control and stress levels stay within the material fatigue diagrams.

    SUPERTECH retainers are made from a titanium alloy and CNC machined for the best possible fit.



    Technical specification FERREA

    • Spring type: single at the intake / dual at the exhaust
    • Outer diameter of the single spring (intake): 21.50mm
    • Inner diameter of the single spring (intake): 15.10mm
    • Outer diameter of the inner spring (exhaust): 22.75mm
    • Inner diameter of the inner spring (exhaust): 17.10mm
    • Outer diameter of the outer spring (exhaust): 29.50mm
    • Inner diameter of the outer spring (exhaust): 22.75mm
    • Seat pressure / installed length: 29.48kg @ 37.95mm (intake) / 36.29kg @ 34.35mm (exhaust)
    • Seat pressure at lift: 65.77kg @ 27.95mm (intake) / 81.65kg @ 24.35mm (exhaust)
    • Max lift: 11.00mm (intake) / 12.00mm (exhaust)
    • Supplied with 20 retainers and 20 spring seats (exhaust)
    • Reference: KT4040

    As with SUPERTECH, FERREA performance valve springs are made from chrome vanadium steel and are heat treated. These FERREA springs are developed so that harmonics and fatigue at high revs stay under control, which keeps the springs from going into resonance; they bring stability and reduce wear on the cylinder head components. Their design also limits pressure loss.

    CNC machined, FERREA retainers are made from titanium.
