K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2012-2023 MAZDA: 3, 6, CX-5, CX-8, CX-9, 33-3024

Have actually been using this filter now for a very long time and I have definitely saved a lot of money. It was super easy to install, I feel the performance of my car is great I've never had issues with it so it doesn't really make a difference with this filter because it's still running great. I do love the quality the ease of cleaning it and how easy it was to install and it was a perfect fit for my car. I have a Mazda CX-9 2016 and it fit great. I do have to say I do use this brand a lot I am familiar with them and it's overall a great product no complaints ever.

It was a perfect fit! Great price, and very easy to install!

As soon as I put it into my car, I felt the motor just easier to rev up and breathing much better. After all the engine is nothing more than a breathing machine. K&N simply the best! Installation was straightforward with no problems.

Good

I have been using K&N products for over 35 years, and they have always worked great. I use K&N air filters, cabin filters, oil filters and home HVAC filters. Every product that K&N makes is outstanding. I have used K&N air filters in everything from Hot Rods to brand new cars, and I have never had a problem with them. I recently purchased this K&N air filter for my new 2019 Mazda CX-5 Signature. The fit was perfect and the installation took about 5 minutes total. Just a quick note, the K&N air filter model number and shape are different for the Mazda 2.5L Turbo and non-turbo engines. They are not interchangeable. One other note. Using a K&N air filter will not cause a car's horsepower to double or the gas mileage to triple, and your car is not suddenly going to start flying. K&N air filters are also not going to damage your engine or Mass Air Fuel Sensor (if oiled correctly) or void a new car's warranty. I can attest to these facts after decades of personal use. However, if you want a great American made product that works as advertised I would highly recommend purchasing a K&N air filter, and any of their other great products. You can't go wrong with K&N!

I was able to purchase it for less than the selling price in Japan.With regular maintenance, it can be used forever.

I have always used K&N filters in my cars since I was a teen. They have always been good products. I have noticed a slight power increase when fully depress my pedal down to the floor but nothing to jump up and down about. Fuel economy I haven't noticed any gains at all. But the plus side is the car doesn't have to fight for air as much as it did with the stock filter.

I add K & N filters to each new/used car in our “fleet”. Have cleaned and re-oiled them dozens of times … they never wear out, even when I need to (sometimes) bend them for tight installation … thinking of all our Saab 9000 turbos over the years.
