I purchased this intake for my 2015 Mazda 6 and man what a difference. The sound is so much deeper and the low rpm power is a bit punchier. My Mazda mechanic even decided to purchase his own after the installation.

HI, I will rate my new K & N air filter after a few weeks. In the meantime what can I realistically expect from an air intake installed on a 2015 Fit 1.5 Liter? Do you have instructions for installation for the Fit? I assume you have general installation instructions since there are so many models and many years involved. Thanks much. I've used the K&N air filter on several of our previous cars (Hondas and a Mazda 3). John Fogarty, Urbana, Ohio

The cleaner works great. I use it along with the oil on my 2012 VW TDI and my wifes 2007 Mazda 3. The comnination of the cleaner and oil is a great combination to keep the K&N filters in tip top condition.
