I got my breathers # 1160. These things are huge, my original one was a lot smaller but there's no name on it and I can't remember where I got it, I think it may be a metco, anybody ever see the metco motorsport ones? The k&ns are like 3" in diameter. Plus they don't seem like there gonna stay in there, they slide out easy with a little tug. My other one was a little harder to pull out. Any other ideas? Thx guys
