Frequently Asked Questions

The Turbosmart TS-0203-1102 block-off cap blanking plate is designed to eliminate the standard compressor-mounted electronic diverter valve found on Ford EcoBoost and BorgWarner EFR turbochargers. Bypassing this OEM valve is necessary when installing a higher-capacity external blow-off valve (BOV) on the intercooler charge piping.

This part is specifically designed to fit turbochargers with integrated recirculation valve flanges, including the Ford Mustang 2.3L EcoBoost, Ford Fiesta ST 1.6L EcoBoost, as well as aftermarket BorgWarner EFR and KKK turbochargers.

No additional custom modifications are required. The Turbosmart billet blanking plate bolts directly onto the original turbocharger compressor flange using the included hardware and seal, maintaining a reliable pressure seal under high boost levels.
