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

Good

The description says it fits the Mustang GT, it also fits the 2.3 ecoboost. I have K&N filters in all 3 of my vehicles. The 1st time they need a filter I put in a K&N lifetime filter. They work great and they are far less expensive than throw aways, over a short period of time. I do the same with my motorcycles. They have never let me down.

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.

Noticeable difference from stock filter. The turbo spools faster and the throttle response is better. Just be careful putting it in since it’s oily. My hand slipped trying to get my air box clipped and I cut my finger lol. (I have a 2016 Ecoboost)

Fits perfect, haven't had the chance to see if it adds more power, throttle response is better and the biggest instant change was MPG. Easily 3 to 4 right out of the gate. That will commeserate with how heavy your foot is.

Felt like I had 1000hp after putting this on jk it works and fit well 👍🏼

I have no idea if this adds power, and I haven’t noticed a rise or dip in MPG in the 300 miles I’ve driven with it. But it took me about 30 seconds to install and I love that it’s reusable so I’d still recommend it. Fits as good as OEM filter, and has a much better feel to it.

The car breathes better, my wallet breathes easier, and I swear the engine sounds just a tiny bit smug. If you want a simple upgrade that makes your Mustang feel a little more alive and add around 2 mpg better fuel economy, this filter’s your new best friend. Just don’t expect it to turn you into Vin Diesel overnight — unless Vin’s secret is better air flow and slightly better fuel economy.

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

Plug and play
