Air Filter
I see a lot of random post out there on specific drop in air filters, has there been any comparisons done? I am looking to replace my OEM with something that has better flow. Any options out there for BMS, AFE, Attack Blue, K&N etc? Would love some recommendations.

I have done some research on this myself, including searching this forum. I doubt you can really go wrong with any of the brands you mentioned but I've seen a lot of recommendations on here for the Green Filter. I think I've decided to just replace the air filter rather than get an entire CAI.
Good luck

I'm a cheap old fart. I just get the GM Delco filter and be done with it. Unless you have the LT4, I don't see more air going into the engine because your filter is a nice color.

I'd say from what you can research online here over the years OEM Airbox and the BMS is your best bet...

these things tend to work best in combination. The BMS + Throttle controller + Soler Throttle body + canned tune, and not even my numb butt could ignore it.

For looks or just because, I like the AFE stuff I have. For cleanability and maybe a little bit of HP, I would use Attack Blue. Otherwise stick with the paper filters and change as recommended in owner's manual and specific usage. IMHO...

Factory air filters have to filter properly and reduce intake noise to meet noise regulations. Good after market filters can filter properly and allow more induction noise as they are not constrained by the same regulations as Gm. So it may be possible that a good aftermarket filter can help with a gain in power as well.

I don't know for sure but if a supercharger in a stock car can make more power by pushing more air than a better flowing filter might as well.

A supercharger is positive pressure. A less restrictive filter will not push air in. It just restricts less. However, if the engine needs 500 cfm and the stock filter flows 600 (just pulling out numbers for comparison), how will 700 cfm help? It helps only if the filter flows 400 and you put one on that flows 500 cfm, AFAIK
