Non-AC Delco Mass Air Flow Sensor... Cool?

[Slim823]

I took my 2004 GMC Yukon to the shop a while back because the check engine light has been on and it bucks a lot when im driving/accelerating. The shop checked it out and told me I needed a Mass Air Flow sensor and a fuel injection clean for $450. I did some research and it looks like I can replace the mass air flow sensor for around $100 bucks. Im a novice at making repairs to my truck but Id like to learn to do a few things. Shops often brag about replacing parts with the original AC Delco parts that were originally made for the vehicle blah blah blah, but does brand really even matter. At Oriellys they have Cardone and BWD, does it matter which one I get? Or is it better if I find an AC Delco one? I already Have a KN air intake ... Thanks
