"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've got a K&N cold air intake, and unfortunately, you must have had some kind of mishap, because you need a new K&N Cold Air Intake Filter, and this is a need that wouldn't ordinarily arise, because your intake came with a filter that should have served you well for life, with its famous million mile guarantee. Things happen, though, and somehow you need a new one, and since you went with this company before, you probably already know about how their multiple layers of lightly oiled gauze take out all the particulates from your enhanced air stream, while providing virtually no obstruction, so that you get a truly maximized air supply. When you don't have enough air, you can't fully burn the fuel you pump into the cylinders, so you lose power and efficiency. However it happened, whether it was a crash, an engine fire, or a nasty spill, you've got to replace this K&N Cold Air Intake Filter right away, because your pumped up intake system depends on this part, and if your filter is damaged, you're letting in particulates that put a lot of wear on your engine. Like the one you had before, this one's guaranteed for a million miles, so drive on. All our customers understandably desire excellent support when buying high-quality car parts from us. That's why we run an always-online information and support call bureau to assist you with your questions. Everyone hates paying for shipping, so your parts come with FREE shipping for each order $50 or higher. If you spot a lower price elsewhere, let us know - we will beat any advertised price for auto parts.
