If you're looking to boost your ride's performance, the APR R1 Diverter Valve is a solid upgrade you won't want to skip. Trust me, I've been down the road of factory units that just can't handle the heat—literally. This valve is built to take on serious boost pressures, so whether you're just starting to tinker with your engine or you're already pushing it to the limits, the R1 has you covered. Its diaphragm-based design means you get lightning-fast response times, which is a game changer when you're on the gas. No more sticking or binding like those piston-based valves, especially in the winter chill.

One of the best parts? This thing is nearly maintenance-free. Forget about the hassle of greasing or replacing o-rings—those days are behind you. The R1 is crafted from CNC-machined billet aluminum and features a high-temperature Nomex-reinforced diaphragm. Basically, it’s built to last, and I can confidently say it might just be the last diverter valve your engine will ever need.

Key Features:

  • Designed to handle extreme boost pressures
  • Friction-free diaphragm for quick response
  • Maintenance-free operation—no greasing or o-ring swaps required
  • Durable CNC-machined billet aluminum construction
  • High-temperature Nomex-reinforced diaphragm for long-lasting performance

Note: This valve has a universal fitment, so it should work with a variety of vehicles. However, it's always a good idea to do your homework to ensure it’s the right fit for your specific setup.

Compatible Models:

Here's a quick list of some vehicles that can benefit from the R1:

  • Audi A4 (1997-2006)
  • Audi A4 Quattro (1997-2005)
  • Audi A6 Quattro (2000-2004)
  • Audi Allroad Quattro (2001-2005)

  • Porsche 911 Classic (1976-1977)
  • Volkswagen Golf MK4 (2000-2004)
  • And more!

Just make sure to double-check your vehicle's compatibility before making a purchase. This little upgrade could make a world of difference in your driving experience.
