Got the unit and I'm very pleased with it. Install some been easier had I remembered which way the filter went in, lol. But overall I like it. Exact swap for my 2015 CBR300R. Mine did come with the bracket.

First, great service delivering to Korea within 3 working days. Second & more importantly, coupled with my Yoshimura exhaust, this K&N filter makes the bike noticeably sound better & generally feels livelier on the acceleration higher up the rev range.

This filter made my bike even more fun to ride. I instantly felt the torque and horsepower go up, and I will definitely recommend this to everyone.
