There are little to no performance gains from adding a "performance" filter to a Mazda3. The benefit of K&N, imo, is cost saving due to reusability.

K&n filters for low mileage things like a motorcycle, cool. For a commuter car, pain in the ass. I would much rather quickly swap a filter for a few dollars vs cleaning, drying and re-oiling every few k km.
Eu, gostaria de um filtro esportivo da K&N ou RS Air Filter...
Yeah you aren’t going to get a whole lot from a K&N ‘upgrade’ except maintenance. Use what the factory specifies.

You can get a better that oem air filter for almost a third of the price air filter get the reusable K&N better performance youtube videos on the steps to replace (both not hard)
I always say this as well. I have a k&N in my car. Both air filters. I've had the dealer pull it out and tell me it needs replaced then damaging it while putting it back in. So now I make sure they know not to touch it
I have 260 on mine. Kept a log book of all maintenance ive had since I bought it in 2013. Regular oil changes at 4000. Even though the oil says 10,000. I use Castro edge. Got a KnN air filter that i clean every oil change.
I bought the washable k&n one on Amazon because I died a little inside when I saw how much they wanted for a shitty filter
If not, get rid of that K&N. High flow air filters let everything in, you do not want road dust a debris getting into your engine, and a K&N is the best way to causing that.
