K&N 63-1122 Air Intake Product Reviews

I like the product, but I guess the quality of the finishing is not as good as I imagined.

So far, so good. Looks good and was an easy install. Will check my map and dyno if needed next. Will see if there is a difference at that point.

The online ordering was easy and I had no problems. As for the item, I love K&N filters but the only suggestion I have is to powder coat the breather tube black. Looks kind of out of place with the black elbow.

Installed this on my 2013 Street Glide in about one hour. The hardest part was the black breather hose. Leave it as long as possible and slide it on with liquid detergent. The intake looks aggressive on the bike. I haven't put on the rain sock yet I'll wait till it rains.
