"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

"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

"Easy to install, will wait till winter's over to see how filter holds up. Usually every year I spent 20 bucks and got a new filter for the car and now this cost twice but is supposed to last forever. I see that maintenance requires K&N cleaners and oil, in time I will see how difficult this will be." posted by: Diggy on September 9, 2009

"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

"I puchased a K&N air filter for my BMW 2004 530I. Ordering was a breeze. The price was right. So easy to install. All I had to do was to remove the fastners that were securing the air filter housing and lift the housing,remove the old filter and install the new filter. More power, better MPG?

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.
