Stock air cleaners do better than open air filters, IMO because there is less evaporation. I used to have the usual chrome open air air filter on my car. Then went back to stock on the air cleaner and I think it helps with evaporation.

This car sat at home outside under a awning for the last 4-5 years. I haven't started it since about May of this year. I fired it up just a few days ago to drive it down to my hanger for the winter, probably permanent home. 20-30 seconds of cranking and it fired up. I am telling you the choke helps a bunch. I did not even open the hood until I got to the hanger and was checking for mouse nests since I haven't driven it since Jan of this year in the snow and ice/salt.
