Ideas for an air cleaner?

[Denee007]

Hi! Car gatherings (Nifty50ee's) will soon to be here (thank goodness!), I'm not going to buy another carburetor, so, I'd like to at least have a nice air cleaner system to compliment my engine compartment.
I've spent way too much time this morning scouring the internet for possibilities. I just picked the one below cause it was different. but I was leaning towards Cold air Intake system? I had noticed last year during the HOT days, the engine didn't run nearly as well as the cool time we're having now, that's why I considered cold air.
Any ideas are certainly welcome!
