Ferrea Single Intake Valve Spring (SINGLE) - VW/Audi / 2.7T 30V / 1.8T 20V / 4.2T 40V
Ferrea Valve Springs are developed from high strength alloys, including premium grade chrome silicon steel. These springs are manufactured with state-of-the-art equipment. Our springs are heat-treated and stress relieved, which dramatically increases the spring’s life.
Strict quality control procedures and cycle testing ensures consistency from batch to batch. Ferrea Valve Springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for today’s aggressive valvetrain combinations.
This Spring requires Ferrea Titanium Retainer #E11031 and Ferrea Spring Seat Locator #SL1025 (Discard OEM Spring Seat Locator).
