FILTERWEARS F153 Universal Water Repellent Cold Air Intake Pre-Filter - Medium

Works great! Tested with a spray bottle and it the water rolls off pretty well (not under high pressure of course) but it gets the job done. It’s a TIGHT fit. So be sure to actually use the finger holes that comes with it. You’ll be able to slide it up right until the widest part of the cone, than you need to put your fingers through the loops and pull it over one side at a time. It’s not easy to get on, but it sure won’t come off.

Dont fit in my filter, I have a Typhon KYN Short ram intake in a civic r18, and didnt work.

I bought the prefilter for my 2008 Civic. Having a cold air with the filter located in the front bumper, i was worried about water possibly getting inside. I looked through amazon at different products and for the price i decide to buy this.Shipped quick and it fits on the filter covers it well and no water is getting in currently which is nice "no hydrolock". Definitely a good prodcut for the price.

Pretty tight on my filter but it's a great prefilter!

I got the pre-filter in, and so far, it looks good. I have yet to test it at all, but it does look a little bit small for the size. It would be nice to know beforehand what exact dimension filters this sock is designed for. Otherwise, it'd be a 5/5 all day!
