2009 STI 330s

Crankshaft sensor is starting to give a bit of jip on start up - sometimes it wont start. thinking it might just be a dry joint as a wiggle on it the other night let the car start. either that or its starting to fail in some way or another.

ideally just going to replace it. is it an OE part only recommended or are people using aftermarket suppliers such as BluePrint etc without issue?
