The OEM plastic, diaphragm-based valve used on Volkswagen Group 2.0 TSI EA888 Gen 4, Gen 3, 3B, & EA113 engines is designed for quiet operation and low manufacturing cost - not long-term performance for people like us! Under increased boost, heat, and repeated load cycles, the factory diaphragm can deform, leak, or fail entirely - resulting in inconsistent boost delivery, reduced throttle response, and power that quietly slips away. The RacingLine Performance Diverter Valve replaces the factory unit with a precision-engineered, billet aluminium valve featuring a robust piston-based design, engineered to deliver consistent boost control even under the most demanding conditions. Whether you’re running a mild ECU calibration or pushing your 2.0 TSI hard on road or track, consistent boost control is critical. By eliminating boost leaks and improving valve response, the RacingLine Diverter Valve helps ensure your turbocharger delivers the performance it’s capable of — every time you press the throttle. Unlike some DV designs, we've engineered the RacingLine Diverter Valve to operate at close to OEM noise-levels. We understand that the loud 'whooosh' is not for everyone! So confident are we in the strength and longevity that we have engineered into our Diverter Valve that we back it with a lifetime warranty. No gimmicks. No unnecessary noise. Just precise boost control, engineered properly. FeaturesPISTON-BASED DESIGNReplaces the failure-prone OEM diaphragm with a precision-machined piston for reliable, repeatable operation. IMPROVED BOOST RESPONSEFaster valve actuation helps maintain boost pressure between gear changes, improving throttle response and drivability. INCREASED BOOST LEVELSDesigned to cope with higher boost pressures found on remapped or track-driven vehicles without leaking or sticking. SpecificationsPrecision engineered for perfect performance.Precision piston and spring assembly eliminates compressor surge.CNC constructed from T6-6061 aircraft grade aluminium.Heat-resistant internal components resists heat soak and deformation.Backed by a lifetime warranty (for first owner).Direct replacement for the factory diverter valve with no permanent modifications required.
