I give this product 10 stars out of 5... <br /> The air filters are absolutely amazing... Hands down the best air filter I have ever ran. Such a crisp, accurate power on the bottom end and a stretch of strength on the top end. Never have I once in my life changed a single thing on my bike and got such a great outcome. I will continue to run K&N oil and air filters in my bike for as long as I can ride. It's so easy to feel the difference in my friend's standard foam air filters. There is just no comparison. And another big perk is the easy installation, I love everything about the filters and I'm blown away that riders still tolerate old fashion foam filters.It is the best investment you could make.
