Product Details

The Flat 6 Motorsports by EVOMS Performance Diverter Valves replace the cheap OEM plastic diverter valves that are prone to leaking boost with tuned and even stock 911s. Flat 6 Motorsports has partnered with Evolution Motorsports (EVOMS), a renowned Porsche tuning company to offer a high-quality diverter valve solution. We leveraged their expertise in tuning high powered Porsche vehicles for decades. Paired with precision manufacturing, these EVOMS diverter valves are built to last.

The performance diverter valves use a 100% 6061-T6 aircraft-grade aluminum housing with an engineered spring rate capable of handling higher boost applications. These EVOMS diverter valves will hold consistent boost pressure, maximizing power delivery along with much quicker recovery, enabling faster acceleration and smoother rapid shifts from the PDK. 

For any 991.2 Carrera running a tune, these are a must-have!


  • Quicker turbo spool up
  • Faster transition between gears
  • Holds higher boost levels where the factory diverter valves fail
  • 6061-T6 billet aluminum construction
  • Tested on 700HP+ 991.2 Carrera


The diverter valves are 100% bolt-on and installation can occur in a few hours.
