prove it because it sure looks like it is. oh and iff its a sachs bearing they actually make parts similar to valeo.
Edit: It does appear to be the sachs interchange part for the same valeo number i posted, meaning same sh!t different pile. I would say take it apart and see for your self but the sachs ones don't come apart easily because they don't use a snap ring on the end. I could be a real douche and say everyone go out and buy a 2000 saab 9-3 oem csc from autozone fab up an aluminum adapter plate and buy the lines and fittings off summit but it probably is easier to just buy the zspeed one. either way you can't tell me its better than this bad azz mofo
Is that thin black ring in the center of the clips in the bearing plastic? if yes that is the front of the piston
