K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2015-2023 FORD: Mustang, Mustang GT, 33-5029

I was skeptical at first, even after reading the article in a well known motorsports magazine and with the suggestion of my SCCA mechanic; but, the improvement in performance was noticeable immediately. My 2019 Mustang GT has plenty of HP and torque as it is, and my primary focus has been dealing with the horrible 4 piston braking system, but this air filter is an inexpensive and pleasantly surprising (albeit modest) performance upgrade. And the fact that I'll never have to buy another air filter again is a nice bonus.

Fits perfectly in the 2019 mustang ecoboost 10/10

Purchased for my Mustang easy install removed the old smelling filter and immediately noticed a cleaner smell

Perfect Filter

Good

I wasn't sure what to expect from this filter. I feel like across the board of aftermarket products, everyone is trying to sell you on an idea, regardless if it's true or, more often, not true. After install I didn't notice anything nor was I really testing to find out. I just continued to drive as normal and see what my thoughts would be after some time. Two things that get brought up about aftermarket filters, power and noise, I would say are negligible. I noticed no difference, seemed stock to me. However, one thing that did surprisingly creep up on me was mpgs. Now in the 2020 GT, I'm sure some purest out there loaths the conversation about mpgs and v8s, but when you daily drive it, its worth talking about. Now for reference I drive 95% highway and usually drive at 80mph for a total of 80 highway miles a day with limited to not traffic. I did not notice any change initially changing my filter. Now I religiously reset my mpg gauge so I know what I should be getting ever trip. What I started to notice with time was increased fuel economy. You see, my mpgs were not going up drastically, a couple tenths here and there, but not before long I was a legit 1 to 2 mpg higher than my baseline. I was consistently getting better fuel economy, I went from 25 to 27. I would struggle to get 4 days worth of fuel, heck sometimes i couldnt; I was cutting it close most of the time but it was doable and it was consistent for the most part. But now getting 4 days worth of fuel out of the car was easier. Look it didn't turn the car into a prius, just in my application it was saving my butt and giving me more peace that after 4 days of driving, I didn't have to stair my fuel gauge going home on my 4th day.

I would like to leave a very positive review. But there is a problem with using this type of filter in some vehicles. In my case - a 2005 Chevrolet Equinox with the 3.4 liter engine, some of the oil from the filter affected the MAF sensor (an air flow sensor) and caused the engine to start idling way to high (1500-1900 RPM). I will have to either clean or replace the MAF sensor as a result of installing this filter. Otherwise, on the positive side, once this filter was installed, I could instantly feel the difference in the engine performance. It's not a *big* difference. But on engines like my 3.4 liter that can really benefit from a little more air flow, you can feel the improvement as soon as you accelerate onto a highway.

Perfect fit for a '22 Mustang Ecoboost

Does what it’s designed to do!

Aspirazione migliorata e si sente, fa piu suono grazie al turbo Come prestazioni non cambia molto, forse l'acceleratore sembra piu pronto o sensibile Speriamo che a lungo termine non ci sia troppo sporco aspirato perche il K&N e spesso la meta del filtro originale Lo strato di olio applicato di fabbrica e molto sottile perfetto come dovrebbe essere, troppo poco non filtrerebbe, troppo tanto aspirerebbe olio Tutto sommato considerando che costa il triplo di un filtro normale ma si puo utilizzare per molto piu di 3 filtri, nel frattempo migliora il suono e in teoria anche leggermente prestazioni... direi che merita ma ricordatevi di fare la manutenzione di pulizia bene (lavare prima + riapplicare olio) circa ad ogni secondo cambio olio

Excellent filters, can't fault them, always fit them to my cars.

Some might not believe this. But this it the best air filter for your Mustang as long as you have no physical engine part upgrades ( stock engine ) your car is equipped from factory with the best box. Even if you tune your octane, get an exhaust or headers. Still the best choice. Don't put other air filter tubes unless you have an engine modification that requires that. Trust that your stock engine even if programmed with run the best with this one in ghe factory box

Muy bien excepto la pegatina está doblada no he podido usarla
