Toyota Yaris GR and Corolla GR Dump ValveThis Blow Off, or Dump valve, has been developed for the Toyota Yaris GR Turbo engine that has the electronically controlled bypass valve (OE Part no. 7. 04654. 08). It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred. Unfortunately, the failure doesnt always result in a check engine light

this can over a prolonged period of time lead to engine fatigue and potentially internal component damage due to insufficient engine lubrication

namely it was observed that cars over 450bhp were randomly getting errors from the stock solenoid dump valve not functioning

The OEM pipe can become brittle and fail under increased boost pressure

there was no perfect solution and a compromise spring was normally installed

Width : Front 10J ET40/ET35/ET25 Rear 10J ET40/ET35/ET25

FMBP6 was developed to remove these restrictions and now features a smooth and enlarged bore size creating a vast improvement in air flow and a reduction in pressure drop

Colours Available : Silver Or Matt Anthracite

After investigation we found the new turbo to be larger on the latest MK3
