Pretty old post but thought Id still add my 2 cents.I just purchased a vitos high flow air filter off ebay.I dont like it.Feels like I taped a paper plate over the intake.Has no flow and its kinda small.I threw the uni back on.Maybe I used to much oil (k@n)Idk but the uni has much more flow.Just going to hold out and get a new airbox made.This vitos is not that great Id feel bad even selling it to someone.
