Hello, all

I'm in need of an AC compressor for a 2008 M3 2.0. I've already gone through 2 new compressors bought from eBay (bad idea I know) the 1st one blew not even 24 hours after being installed and the second one didn't even make it into the car. It was bad out the box. I've check most of the auto parts stores in my area. AutoZone, AAP, and O'Reilly's. They're so damn expensive. I don't want to get one from Mazda because I know I'll be spending hell of a lot more. I want to get my toes wet with other options. If it comes to it, then I guess I'll just got to Mazda 😖

I've been looking on carparts, partsgeek, and other sites that sell cheap car parts. My questions is, does anyone know the stock Mazda 3 spec. Like the clutch grooves count 5 or 6? Clutch diameter, which serpentine belt size? These sites have a lot of things I don't know. I just need a darn compressor. Someone please help me!
