Racingline 2.0TSI EA888 Gen 4 Diverter Valve
The Racingline 2.0TSI EA888 Gen 4 Diverter Valve is an essential upgrade for Volkswagen Group 2.0 TSI EA888 Gen 4 engines. The original valve is made from plastic and uses a diaphragm design, which is intended for quiet operation and low cost. However, this isn’t ideal for those seeking long-term performance.
Under higher boost levels and repeated stress, the factory diaphragm can deform or even fail. This leads to issues like:
- Inconsistent boost delivery
- Reduced throttle response
- Loss of power
The Racingline Diverter Valve is designed to solve these problems. Made from precision-engineered billet aluminium, it replaces the factory valve with a durable piston-based design. This allows for:
- Consistent boost control, even in demanding conditions
- Improved valve response
- A reliable turbocharger performance every time you accelerate
Whether you’re using a mild ECU remap or pushing your 2.0 TSI to its limits, maintaining steady boost pressure is critical for optimal performance. This valve helps eliminate boost leaks, ensuring your engine performs at its best.
We’ve designed the Racingline Diverter Valve to operate at similar noise levels to the OEM valve. We understand that some drivers prefer a quieter operation without the loud ‘whoosh’ noise associated with other designs.
For your peace of mind, we offer a lifetime warranty on this product. There’s no gimmick here—just reliable boost control and engineering that lasts.
