The strongest, most durable and longest lasting diverter valve for the 1.8/2.7T engines is back in stock @ GMP Performance after short stint on the back ordered list we have finally received our new batch fresh off the assembly line as they say :)

We have plenty in stock now for those who have been waiting and we would like to throw in a free GMP license plate frame for the first 5 R1's that get sold. As you can see its completely chrome with black lettering and is now 50 state legal as it no longer hides the new inspection sticker and or barcode that some states now are switching to that older frames used to cover up.

The APR R1 diverter valve was designed to be the ultimate solution to the problem of unreliable factory and aftermarket diverter valves and to be the leader in performance. Although most are of good design, factory diverter valves are built in a very conscious manner and the materials and overall life and reliability suffer.

The APR diverter valve is a diaphram-based unit that has a response time as fast as the stock unit using a membrane that has millions of cycles without failure. There is not a piston style diverter on the market that can compete with these new APR diverter valve matching performance, reliability and maintanance free durability. Fitments for all cars with Bosch type diverter valves including VW and Audi 1.8T's, Audi 2.7T's and Porsche Turbos.

Highlights of the APR R1 Diverter Valve Include:

Diaphragm-Based Valve
High-Temperature, Nomex-Reinforced Material for Extreme Durability
Zero-Friction
No Sticky O-Rings to Maintain and Grease
No Pistons to get Stuck
Consistent Performance Year Round
Flow-Optimized, Investment-Cast Main Housing
Stainless Steel Vacuum Fitting
Zero-Maintenance Design
Built with Finest Materials and Surface Treatments
Fully Machined and Assembled at APR Headquarters in the United States for Optimal Quality Control
For the performance enthusiast, the diverter valve is an important component whose proper operation is paramount to optimal engine operation.

Enter the R1: APRís R1 diverter valve addresses all of the reliability problems of the factory-supplied diverter valves and aftermarket replacements and takes performance to the next level. The R1 is a diaphragm-based valve. A diaphragm is the best option for a diverter valve for several reasons. First off, a diaphragm has negligible friction. Piston-based valves have considerable friction from the piston, o-ring, and bore assembly. The lower friction R1 diaphragm equates to faster response and better overall performance. Secondly, diaphragms do not require the periodic greasing that piston-based valves do. Piston-based valves must be qreased periodically (usually every year or sooner), requiring removing the valve from the car, disassembling and reassembling the valve. The APR R1 was designed to be maintenance free for the life of the product. Thirdly, a diaphragm based valve will never have a stuck piston. Piston-based valves periodically incur stuck pistons (especially if the required maintenance schedules are not followed.) Due to the lack of a piston, the APR R1 solves this problem.

The R1 is designed for optimal performance. The main body of the valve is investment cast in an aluminum alloy. By utilizing this casting process in lieu of a more conventional machining process, APR was able to optimize the internal geometry of the valve to provide the ultimate in flow performance. This geometry cannot be created utilizing conventional machining. As such, the APR R1 has much better flow characteristics than other diverter valves. Combined with the low friction diaphragm assembly, this equates to a valve that is truly a performance leader.

The materials used in the R1 are standard setting. The diaphragm is created out of high temperature material and incorporates a Nomex fabric reinforcement layer for enhanced durability and a diaphragm that will never tear. The alloy main body is finish machined at APR and receives a multilayer corrosion resistant and cosmetic enhancing finish. All machining and final assembly takes place at APR headquarters in the United States for optimal quality control and consistency.
