R1 Diverter Valve by APR Tuning
The APR R1 Diverter Valve is a critical performance upgrade recommended at all stages of performance as it replaces the failure-prone factory unit. The R1 is designed to withstand extreme boost pressures at the highest levels of performance while offering lightning-fast response thanks to the unit's friction-free diaphragm-based design.
Unlike piston-based units that can stick and bind in the winter, the APR R1 is virtually maintenance-free, requiring no greasing or o-ring replacements, as is common with other units. Constructed from CNC-machined billet-aluminum with a high-temperature Nomex-reinforced diaphragm, the R1 is designed to be the last DV upgrade the engine will ever need!
