Water ingress is also very unlikely unless you drown the filter.
Have you ever seen this on a real race car? I would be interested to know because we are not aware of anything like this and we have a large number of race cars running some of our software and hardware running open filters subject to the elements.
My concern is from my last track day at VIR where I got a ton of new paint chips on the car and a lot of them are in the vicinity of intake. I've never experienced this when I was on the Nurburgring or speeding down the autobahn. I guess the tracks around here are not as clean as the ones in Europe. I got a couple of chips that went straight though the paint and to the bare metal on the hood. I was not a happy camper but I got some trakktape for next time. I'm sure it would be a one in a million shot for the debris to hit the filter just right to puncture it, but with my luck, it would happen to me.
