APR R1 Diverter Valve for Audi, Porsche, Volkswagen - CNC-Machined Billet-Aluminum
$280.95

Product Description

If you're serious about performance upgrades, the APR R1 Diverter Valve should be on your radar. This isn't just another part; it's a solid replacement for that factory unit that’s prone to failure. Trust me, once you install this, you'll notice the difference right away.

The R1 is built to handle extreme boost pressures, which means you can push your engine without worrying about it giving up on you. Thanks to its friction-free diaphragm design, response times are lightning fast. Unlike those piston-based valves that can get sticky when the temperature drops, this one is virtually maintenance-free. No need to fuss with greasing or O-ring replacements—just install it and enjoy the ride.

Constructed from CNC-machined billet aluminum, this valve is tough. It features a high-temperature Nomex-reinforced diaphragm, so you know it’s built to last. Honestly, this could be the last diverter valve you ever need to buy for your engine.
