Product Description

The Turbosmart TS-0552-1402 ALV40 GenV Comp-Gate 40 mm anti-lag valve is a high-performance fresh air valve engineered for turbocharged motorsport applications. Unlike traditional wastegates, this anti-lag valve safely diverts compressed air from the turbocharger into the exhaust manifold ahead of the turbine during low throttle angles, helping spool the turbo faster without relying on throttle-based anti-lag strategies that can cause harmful combustion events.

Constructed with a sealed twin-chamber actuator and a purpose-built 40 mm valve, the TS-0552-1402 offers reliable operation under both boost and vacuum conditions. Its clockable actuator housing, robust stainless-steel body, Nitronic-60 valve guide, and supplied adapter fittings make installation and fabrication adaptable for a range of performance setups. This valve is ideal for engines running dedicated anti-lag strategies, custom motorsport turbo systems, or those seeking to improve turbo spool-up with a durable, dedicated component.
