I personally don't think it will hurt the filter, but here is what you could do for a fix. Buy some prefilter material from one of the snowmobile aftermarket suppliers (SLP) and sow velcro strips to it then get some velcro strips that have the adhesive, and adhere the stips to the fiberglass so it is around the hole, then velcro the prefilter to it. This stuff is waterproof and snow proof and it will not restrict air flow in any way. I have been using this stuff for years on my sleds and have never gotten a wet filter even riding in snow that comes up over the hood. Just an idea. Gene
