11747649407 that looks like the one. I purchased that same one from ECS and had it replaced about a year ago, no issues/codes that I'm aware of. (MHD tuned and I haven't seen any engine codes on the app). I only replaced mine because it would make an intermittent buzzing noise, but no engine codes.

I didn't DIY it myself at the time, but since then I've diy'd my plugs and coils and the "wastegate acuator" it looks like it would be a fairly easy swap. Gain easier access by remove the intake piping along the valve cover and the PCV crankcase hose connected to the valve cover and intake piping to have easier access to the pressure converter/actuator
