Take the foam out for sure. I just put the bdx intake on my 09 hcr, and love it. Heat tape all around the cover so no snow gets in the top. I also glued up all the cracks around the bumber and nose piece, so no snow gets in there ether. I filled it full of snow, and now barely any gets in, and still working on all the cracks. The weight loss is great, and throttle response is great.
