Racingline VAG 2.0TFSI/2.0TSI/2.5TFSI/4.0TFSI Diverter Valve
The Racingline Diverter Valve is an essential upgrade for Volkswagen Group vehicles with 2.0 TSI, 2.5 TFSI, and 4.0 TFSI engines. This part supersedes the original plastic valve, enhancing performance and reliability under demanding conditions.
Why Upgrade to the Racingline Diverter Valve?
Many standard diverter valves use a plastic, diaphragm-based design that is not built for long-term performance. The factory valve may fail under increased boost or heat, leading to:
- Inconsistent boost delivery
- Reduced throttle response
- Power loss during acceleration
The Racingline valve is made from precision-engineered billet aluminium and features a sturdy piston-based design. This allows for:
- High-level boost control, even under extreme conditions
- Quick response for better acceleration
- Elimination of boost leaks
Key Features
- Compatible with 2.0 TSI engines from 2003 to 2020 (EA888.1, EA888.3, EA888.3B) and 2.5 TFSI models from 2009 onwards.
- Also fits 4.0 TFSI models from 2013 to 2018 (EA824). Two diverter valves are required per car.
Performance and Sound
The Racingline Diverter Valve is engineered to operate close to OEM noise levels, catering to those who prefer a quieter performance without the loud ‘whooosh’ that some aftermarket valves produce.
Durability Assurance
With its robust construction, the Racingline Diverter Valve comes with a lifetime warranty. This reflects our confidence in the product’s strength and longevity, ensuring you enjoy performance upgrades without worry.
