They would all work for both applications, but I'd probably not use the Purolators for autocross since the engine will probably be doing high revs with the oil not always at full temperature.
I'll be the contrarian and nominate the Purolator Boss. That's the exact model number one of my vehicles uses and it is very capable. Of course I don't autocross my suv.
I'd pick one of the ones on the top row so I didn't have to stack them all again... they're gonna all get used anyway right?
It's not going to make much difference. People around here make mountains out of molehills. The main thing is recognize the service life of the filter and oil you use.

True indeed ^^^^^^^^^
A Wix air filter is a good choice... Or a STP premium air filter... Which is 98 percent efficient using the fine dust version of the ISO 5011 test. A much harder test vs the coarse dust test.
