Rated 5 out of 5 by This product is outstanding! I have this product in every car that I have ever owned. November 29, 2016
Rated 1 out of 5 by Oil from filter caused engine not to run. The oil coats the MAF element. Engine stopped running after about an hour of run time. Cleaned MAF and installed regular air filter, car runs great. It's a few weeks and still running great. November 28, 2016
Rated 5 out of 5 by Happy Excellent product very pleased with my purchase can really feel the difference when I hit the gas November 14, 2016
Rated 5 out of 5 by Great air filter Great air filter easy installation just minutes to put in November 6, 2016
Rated 5 out of 5 by Works well I bought this because the store mgr. said it would pay for it self in three filters plus it would help with gas mileage. So I did . I have shopped at pep boys since 1975.. Yep I'm getting old.. Seen some changes. And filters have always been that need changing more often than not. I live in dusty area and I like this filter because I can clean it often. It works well and it is easy.' October 25, 2016
Rated 5 out of 5 by This product is great I have used this product in all of my cars and are satisfied with the performance. October 17, 2016
Rated 5 out of 5 by 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. October 17, 2016
Rated 4 out of 5 by 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 October 17, 2016
Rated 5 out of 5 by K&N 33-2111 My fault, ordered stock filter, when I got under hood found I had a air box instead. Am returning, my fault, still great products, have them on all my vehicles October 10, 2016
Rated 5 out of 5 by Excellant product This product performs as stated by manufacturer. October 5, 2016

Rated 5 out of 5 by Super good. Warranty is excellent. Super good. Warranty is excellent. September 11, 2016
Rated 5 out of 5 by 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. September 10, 2016
Rated 5 out of 5 by Helped performance 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. September 7, 2016
Rated 5 out of 5 by Great filter 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! August 30, 2016
Rated 5 out of 5 by 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. August 25, 2016
Rated 5 out of 5 by Great Filter Can never go wrong with K&N filters. Glad they had my particular filter in stock. August 25, 2016
Rated 4 out of 5 by 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. August 22, 2016
Rated 5 out of 5 by 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. August 15, 2016
Rated 5 out of 5 by Simple decision Not the first K & N air filter I've bought n installed in my cars... Great product, RE-USABLE/WASHABLE and forever lasting ! Tad expensive... August 8, 2016
Rated 5 out of 5 by This filter enhances air flow to the engine 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. August 7, 2016
Rated 5 out of 5 by K N fan 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. August 6, 2016
Rated 5 out of 5 by Awesome filter I bought this for my 2008 Toyota Sequoia. Worth the additional dollars knowing I will never have to buy an air filter again. August 2, 2016
Rated 5 out of 5 by 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 July 31, 2016
Rated 5 out of 5 by 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. November 9, 2015
Rated 5 out of 5 by Excellent! 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. November 5, 2015
Rated 5 out of 5 by K&N Filter 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. October 26, 2015
Rated 5 out of 5 by Air Filter Excellent product September 26, 2015
