If you live in wet/humid areas... Then this is a must for your K&N Intake. It is going to protect your engine from intaking water and protect your filter element from getting saturated on rainy days. The wrap fits really tight, which I was concerned about at first, but after riding with it and comparing it to my other bike which has the similar Screaming Eagle intake with the wrap on it. I now appreciate how tight it fits, because the Screaming Eagle wrap is so loose that it worries me that it will not stay on.

The fit is great the only complaint I have is it turned grey quick even after I oiled it again

I am replacing with the same style after years of excellent performance. Time and weather took its toll but the performance was still good 👍 👌

It had rubber that wasn't trimmed to seam. So it looked off.
