Rated 5 out of 5 by Towzik Awsome Product
Very good product. I have personally used K&N product for past 20 years in different cars. And I have been 100% satisfied with K&N.
However the part number in the K&N catalog is wrong for the 2016 Toyota Prius. For the cabin filter and the engine air filter.

Rated 4 out of 5 by strougall Best filter for the money
This is my 10th k&N filter. The first thing I do when buying a new vehicle is install one of these.
They just work. 1MPG + 10HP = Money well spent

Rated 5 out of 5 by jgdfotog Excellent quality.
The stock paper Motorcraft air filter is very good quality. After installing this in a stock air box, for my F-150 loved the extra air. F-150s need all the help they can get. 330 cubic inches drawing air through a 2 inch hole? It can't breath. I have used K&N filters for over 30 years and have never had a problem.

There's not a lot a driver can do to help a modern engine but air flow is one of them. I replaced a heavy stock air filter with this K&N before a long road trip. My milage improved about 20% in a 2012 F150 with the ecoboost. The filter more than paid for itself, and I continue to get more than one extra MPG around town.

Bought this for my 2015 Corolla Sport + and WOW! what a difference it has made. The engine revs with more power and is much more responsive. Before the engine seemed to strain to accelerate now it just does. Worth every penny!

Rated 5 out of 5 by Saturnpresreg It outflows all other air filters.
This air filter allows your vehicle to breathe. Less restriction - more power, better fuel economy, and smoother acceleration. This leads savings at the pump, and less repairs - saving you more.

Rated 4 out of 5 by Docc A maintainable air filter
The K&N air filter I bought for my '69 Cougar fit in diameter but was a bit large in height; my air filter housing cover doesn't completely seal flush with the base.
K&N filters are great because they let the engine breathe better and you can clean/service them for a long time.

Rated 5 out of 5 by Powerdbyhemi Best 39 bucks I ever spent!
I always try buy top of the line stuff for my car. But when kept petting off to go with one 20 bucks cheaper and with fabreeze in it that dint do a darn thing btw lol. This air filter doesn't need be change for 100,000 miles. Plus it came in a sealed package and was pre oil up for the 100,000 miles then just wash off and spray some more k&n oil on it. not sure why everyone not using it.

The filter fit perfectly in the filter box and will help air get to the engine better. Just installed so hard to comment on continued improved performance.

I had kn air filter system for my Tacoma Toyota truck. Love it and can feel a enhance peak performance and mpg help. Of course all other fuel elements o2 sensor are good. KN on my Prius. Can feel an enhance peak performance Feel car is a bit smoother engine feel than factory filter. And see my mpg go up a bit on Prius too. No joke. You will only feel and see difference if u really pay attention to your car health.

I bought this for my 2008 Toyota Sequoia. Worth the additional dollars knowing I will never have to buy an air filter again.

Rated 5 out of 5 by Skybird9 The last air filter you will buy for your car
The K&N series of air filters makes a lot of sense and saves you a lot of dollars over the life of your car. The K&N filter costs about 3x what a standard high quality paper filter costs Being able to clean and reoil my filter starts saving me money on the 4th filter change and beyond. I also get about 1 mpg better fuel mileage

Rated 5 out of 5 by GrapsJunior Excellent Air Filter from K&N
When I last had my oil changed in my 2003 Jeep Liberty, I was given a choice to either keep my existing air filter or add/buy the oil change company's stock part. I did not mention that I bought a K&N filter for my previous vehicle, a 1993 Nissan Pathfinder which benefitted from a washable, cleanable air filter. I paid for my oil change and headed to my local Pep Boys store. I bought the K&N air filter for my Jeep and did not complain about the higher price due to a quality filter. I have increased power to my Jeep and enjoy zipping through traffic without a power lag ! Thanks, Pep Boys, for carrying K&N parts.

Got more power now and best response on my G37 2010. Just wash it when dirty. This filters are expensive but worth the extra dollars on the long run.

I have been using the K&N air filters for a long time and I have never had a problem with them and neither will you as long as you clean them with K&N cleaner and let to air dry.

I have good use and sales with K&N filter's. I recently had a coupon for $10 off from Pep Boys and used it to buy the 33-2385 model filter. The way I drive. I did not need to clean my last trucks(same part number) K&N filter for 50000 miles.

Have one for both SUV I own as soon as you buy a new car or truck replace air cleaner with k&n and your done. More power and torque and better fuel economy.

Rated 5 out of 5 by Handsomish Improvement in Mileage for the cost of two paper filters
Only a 5 percent increase in mileage, compared to a 12 percent for my previous K&N filter. The last car wasn't fuel injected though, so not as efficient in the first place. But just the fact that I won't have to purchase another filter for the vehicle for the rest of it's life, for a price barely over the cost of two filters makes this an excellent decision. I also like that K&N now includes a sticker to put on your air cleaner to notify mechanics that this is a reusable filter and to not through it away, since I am not always the person driving the car, and someone else might be convinced to buy a new filter.

Awesome filter that has a lifetime use. Just buy the cleaner treatment and you can wash and re-use. It is thicker than the ones purchased from the dealer and is easy to install.

Rated 5 out of 5 by Poordad They work.
Bought this to replace one I tore when cleaning. The only downside is you usually have to clean your mass airflow sensor shortly after install or reconditioning as the excess oil on the filter will coat it. Other that that performs as advertised.

Rated 5 out of 5 by Verified Reviewer The best in many ways
I have used them in my vehicles for years and have never been disappointed. They are not just for racing. They have given my vehicles better fuel mileage for sure and K & N claims increased horse power but I have not run them on a dyno. I Have to say looking at it from the "green" side I no longer ad to the landfill. Follow the instructions to wash and lube, very easy!
