Surprised with how well it works
I installed this K&N filter into my 2019 Altima a couple of weeks ago and have been pleasantly surprised ever since. Installation took me quite literally one minute, very easy. I have no experience with cars either. The horsepower/torque boost is definitely noticeable. My car feels much more responsive on the low end and where before my Altima always felt like it would take a second once the gas was pressed to actually get going, now it feels near immediate. I haven’t applied any additional modifications to my Altima, this single air filter has gotten my car to a place I’m happy with performance-wise. In terms of fuel efficiency, my average MPG has actually slightly gone up since installing this filter, however only by about 0.2-0.3mpg. I wouldn’t expect much in terms of improving MPG from this filter, however you can be fairly confident that it at least wont worsen fuel efficiency. Overall, very happy with the purchase, it’s a no-brainer in my opinion.

Great Value
This is my first K&N. People have always suggested getting one because you save money because you purchase air filters less. I was hesitant because of the price, but in the long run it makes financial sense. It is washable and reusable is a plus. Easy to install and perfect fit.

Perfect fit 30 sec installation
Perfect fit for any 2019+ Nissan Altima and it fits ALL TRIMS. If you’re experienced with cars it’ll take you under 30sec to complete the installation. Improved my mpg and makes the 2.5 engine sounds more masculine. HIGHLY RECOMMEND. It also comes with those stickers in the photo. :)

Do it!!!
Don’t waste your money paying for filters from dealerships or oil change places. GET A K&N FILTER!! Easy to clean and has a lifetime warranty if you ever need to replace it! Both my vehicles are now equipped with this filter and the air flow is so much better! Comes with a sticker to let businesses know not to replace the filter.

Podría ser perfecto
El producto se aprecia muy bien y prometedor. La caja llego en mal estado y los sticker informativos dañados
