Billet Aluminum Piston Diverter Valve

This latest evolution combines a full replacement solenoid-controlled recirculating valve with a blow-off valve adapter, offering a unique sound and improved performance. It is constructed from billet aluminum with a piston-based internal design, providing enhanced reliability and lightning-fast response compared to OEM solenoid valves, which are prone to diaphragm rupture and boost leaks. This valve is specifically designed to address fitment challenges on B7 and B8 chassis Audi A4 and A5 models with the 2.0T engine. Its shorter installed height allows it to clear the chassis frame rail, an area where standard valves and spacers would conflict. The FMFSITAT-C also includes an intake manifold tap for vacuum reference, with additional provisions for boost gauge signals or water/meth injection triggers. It fits 1.4T, 1.8T, and 2.0T FSI and TSI engines, including the late 2011-2013 2.0 engine with the IHI turbo. Please note: it will ONLY fit 1.4 turbo engines up to early 2013 where the turbo is front-mounted and will not fit engine codes CMBA & CXSB. For 1.4T engines, the additional fitting kit FMBGFK3 is required. The product comes with all necessary parts for installation, including a wiring harness, solenoid, PCV adaptor kit, and an uprated blue spring.
