Product Details

The APR R1 DV Higher Pressure Spring is a performance upgrade component designed to increase diverter valve spring tension for turbocharged applications running elevated boost levels. This blue-colored replacement spring allows the APR R1 Diverter Valve to handle higher boost pressures without premature valve opening or boost leak issues.

Key Features:

  • Higher pressure spring rate to accommodate increased boost levels
  • Direct plug-and-play compatibility with APR R1 Diverter Valve
  • Blue powder-coated finish for identification and corrosion resistance
  • Simple installation with no special tools required
  • Prevents boost creep and maintains precise boost control

This upgraded spring is ideal for modified vehicles running aftermarket tunes or upgraded turbocharger systems that exceed OEM boost pressure specifications. The stiffer spring rate ensures the diverter valve operates correctly under higher pressure conditions, maintaining optimal engine performance and preventing compressor surge.
