Relief valve for 1.4TSI 122/125HP CAX Engines.

The RTMG Performance Pressure Relief Piston valve is a bolt-on valve which replace the factory plastic Diverter Valve which fails often. The Valve works perfectly without any check engine light in the dashboard and it cooperates with the ECU because it is Solenoid driven. The Piston type valve is engineered to remedy the issues experienced with the factory valves when their diaphragm rapture or when their piston breaks which result in boost leak and premature wear of the turbocharger. Our valve is designed to work a lifetime without fail because it is serviceable.

Seat Ibiza CUPRA 1.4 TSI Review by Shankar
Got the BOV installed. Very easy to install. Sounds amazing. The noise it produces is by far the best in the market. You pay for the quality. R-TMG are the best in the business for sure. I will be buying more products from them. (Posted on 11/9/2019)
