It was what I expected

Works good by the hose does not connect tightly so the filter rattles a bit.

Nice billet mounting bracket. I wasn't really fond of the PLASTIC cover over the breather element. I would have paid extra $$ if it would have been made out of aluminum instead of plastic. Harley's are NOT made of plastic.
