"I didn't notice when my air filter is at the door. The shipping is unbelievable fast and the air filter is better than I expected. What I like about the product is that when I replaced my old conventional filter with K & N filter, I see my engine running like new, it's quieter and more powerful. I am very happy with this product." posted by: therealthing on April 21, 2009

"You can see the filter superior quality when compare with filters installed on the dealerImprove performance as claim not sure But I m sure the filter are better that OEM" posted by: Luiscfq on August 15, 2014

"After I received 2 filters for my 2 cars, I was alarmed by visible less filtration fiber in K&N filters. In many instances you can see small openings in the fiber. Fiber has some oil that helps to collect dirt from air, but sometimes that can also mess up ignition things. Filter build solidly, but the main working function clearly not as good as a regular ( original) filter. I went on other web sites to read reviews about it. Many people impressed by it's solid build, but informed ones all point to potential problems from using it. Bottom line it will allow more air, but at expense of allowing more dirt in to an engine. Following common sense, in industrial settings nobody uses type of filters as K&N does, in semiconductors manufacturing, in clean rooms all filters are HEPA, and fiber type similar to regular (original) filters. Using K&N filters might void warranty on your car. Will be returning these today, and will get original ones at third of the price." posted by: Rusm on September 12, 2011 view all 7 reviews

"Two purchased for 2007 Infiniti G35 Sedan. Installation was fairly simple although the K&N's are a snugger fit in the housing than the OEM's. I also bought the recharge kit to clean them when needed so theoretically, I won't have to buy new ones again. Unlike some have profferred, I am not able to tell any HP difference...but that's not why I purchased." posted by: BlackCloud on November 28, 2008

"The filter and product itself is tops but there was no installation manual or instructions on the proper way of cleaning the filter and applying the oil after cleaning. I had to refer to a Simota Cleaning Kit with a similar material to K&N to be educated on how often it should be cleaned and the directions in cleaning." posted by: Tony on April 20, 2009

"Due to the "oiled" nature of this product, it is difficult to install in the 2010 Ford Edge (3.5L). I had to disassemble the air intake duct in order to fit the clam shell back together. Took about 15 minutes over all. This negative is primarily aimed at Ford designers." posted by: on May 31, 2011

You need a new air filter for your vehicle, and up until now, it's been a routine replacement, which you deal with fairly frequently, so that you keep getting good air flow. You've come to understand how important your vehicle's air supply is for its performance, though, because if you're not getting enough oxygen to burn the fuel you're pumping into the cylinders, you're not operating efficiently, and you're losing power, torque, and fuel economy. This time around, it's time to take a step up to a K&N Air Filter, because this performance filter comes in a configuration that will fit right in where the old one did, and you'll get an immediate increase in airflow and power. That's not all, because although you pay a little more for a quality K&N Air Filter like this, it's the last one you'll ever need to buy, because when it gets dirty, you just clean it, and it takes a lot longer to get dirty than your paper versions - you can drive for up to 100,000 miles, depending on conditions. Then you just clean the cotton gauze, and you're back on the road, with a million mile guarantee, so this filter will outlast your car. Auto parts customers desire high quality technical support when purchasing quality auto parts. For all our customers, we make available an always-online help call desk to help you with your questions. Everybody hates to pay for shipping, that's why we always provide free shipping for every order $50 and higher. If you find a better price, call us - we will beat any price advertised elsewhere.
