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!

  • Premium friction-free diaphragm-based design
  • No sticking or binding like pistons
  • Fits 1 inch inlet and outlet hoses
  • No maintenance like pistons
  • Nomex-reinforced diaphragm

Manufacturer's Warranty — APR

APR warrants its products to be free from defects in materials and workmanship prior to installation. Coverage runs to the original purchaser only and is non-transferable, and the warranty period varies by product — each part carries the term set by the manufacturer, so check the coverage that applies to the specific item. Not covered: labor; misuse or abuse; improper installation; failure of related or connected components; and any product not purchased from APR or an authorized dealer. Grey-market purchases are not supported — claims on product bought outside authorized distribution are declined. Claims are made through APR or the authorized dealer or reseller you purchased from, so if you bought it here, contact PitStopTuning and we'll file the claim with APR for you.
