I haven't put a lot of mileage on since the addition, but it seems to have helped both issues.The installation was pretty simple, and the instructions were pretty comprehensive. Knowing K&N products, it will be a long-term improvement to the intake package the car came with." —John R from Latham, NY bought a K&N 69 Series Typhoon Intake Systems for a 2011 Mazda 3.

"I have used a high performance filter from K&N before on a much older vehicle, and just as before, K&N delivers on their promise of increased power and efficiency. I installed the system just before a road trip, and recorded just over a 10% increase in fuel economy as well as a quicker throttle response. Install took me 2.5 hours because I read directions like 4 times before doing anything." —Kevin S from Austin, TX bought a K&N 69 Series Typhoon Intake Systems for a 2011 Mazda 3.
"I didn't have any problems installing my K&N Typhoon Air Intake System. By installing this air intake in my car I have notice an increase in my miles per gallon, more horsepower, and more torque. My car also has become louder and that really sounds great. I can hear the engine growl for more air. I really recommend this awesome product to any import car owner who wants to gain more mpg,horsepower and torque. Now with the help of this complete cold air intake system I can easily pass slow moving traffic on the highway." —Jose P from San Marcos , TX bought a K&N 69 Series Typhoon Intake Systems for a 2011 Mazda 3.
