Take 1 look at the photo, it's not a true "ram air". And guys drive all the time with open element filters with NO box whatsoever. The fact that this box has 1 opening on the front side doesn't mean it's going to get wet in a little rain. There's hundreds of thousands of vehicles out there with open element filters and no water issues from driving in rain.
Now offroading and pounding puddles, I'd be slightly concerned, but again, still 10000xs better than an open element style intake that tons of guys run (roush, AFE without a lid, K&N, airaid, etc.).
Also on a practical side, it's an oil gauze filter, it REPELS water, it's not going to soak water up. And you could even hit a big puddle and splash some in there, most will just run to the bottom of the box and not drench the entire filter. You'd have to sit there with a super soaker spraying it in the tiny inlet opening to really get the filter wet and get it to ingest water.
1 piece of duct tape and bam, it's enclosed just like the factory air box if you're hitting seriously dirty conditions that you need to seal it off like a factory box.
how long is that price good till?!
