Cowl Intake pre-filter

I got a sample pre-filter for some of the AC units at my work and thought it would fit the cowl. Turns out the sample looks as if it was designed to be used as a cowl pre-filter. It's held on by magnets and can be removed, cleaned, and reinstalled in under a minute. what do you guys think?

I havent tried it at highway speed yet, but since there is a low pressure zone there and most of the wind will be forcing down on it, I dont think there will be an issue.

I'd be concerned that a crosswind gust would blow it off and crack a windshield, your own or possibly that of the car in the next lane over or behind. Pics are a bit too blurry to get an idea of what the filter mesh is like.

Might work well for keeping crap out of the cowl, but don't forget the cowl is open to the air at the bottom too for the drain.

I could definitely use it on mine, The plastic broke in a hail storm and ever since then I get leaves blowing thru the vents.

didnt think about hail, but they gave me a hail guard screen as well, just need longer mounts.

I looked into the magnets and they are neodymium, I don't think they are going anywhere, especially with the downforce the cowl area produces

Give it a test drive at 80 mph and see how it holds up.

got a little test run where i got up to 70 for about a mile, the prefilter didnt budge a bit. wanted to get up to 80 but the expressway was a parking lot. sorry about the shaking, couldnt find my suction mount so i had to mount the gopro to the visor

that intake looks a bit rigid, how well does it handle the engine rocking?

note: the prefilter above is not for an air intake, it is to keep gunk out of the cowl and potentially clog the cowl drain.

Not to get off subject or hi-jak this thread but the photos in the first post are all blurry and has a big photobucket logo across a big part of the photo- can anyone tell me why that is and can it be gotten rid of

All of the photos every thread has the same thing

Sorry, I forgot photobucket is still trying to extort money from people

I have posted them from flickr instead, hopefully they are a bit better

Ah, now we can see what the filter mesh looks like.
Looks like it'd be handy for folks that park under trees.
