Performance Dual Valve Spring Kit with Titanium Retainers for a Audi 2.5T FSI
Our Performance Dual Valve Spring Kits for the Audi 2.5T FSI offer a comprehensive valvetrain upgrade engineered for aggressive performance builds. By combining high-tensile Chrome Silicon Vanadium springs with aerospace-grade Titanium Retainers, this kit delivers enhanced valve control and a significantly elevated RPM ceiling.
Designed to support sustained high-RPM operation—safely up to 8000 RPM—the system increases spring pressure while reducing valvetrain mass to minimize valve float and maintain precision at extreme engine speeds.
The Supertech valve springs are crafted from premium Chrome Silicon Vanadium steel, providing excellent fatigue resistance and consistent seat pressure. Each spring is computer-modeled to maintain optimal harmonics, ensuring maximum durability and performance under stress.
The included Titanium Retainers are CNC-machined from military-grade alloy, reducing inertial load while delivering exceptional strength—ideal for race applications or high-performance street use.
