K&N Universal Air Filters are constructed with ultra-strong molded pliable rubber flanges that absorb vibration and allow for secure attachment. They can also be stretched up to 1/16-inch to fit in-between sizes. The K&N filter is economical because it’s the last air filter you’ll have to buy for your car. It can be washed and reused many times, and since you can usually drive up to 50,000 miles between servicing, you won’t have to clean it very often. And every K&N filter is backed by K&N’s Million Mile Limited Warranty.
Most air filters on the market are a compromise. Many high-performance filters deliver better airflow, but sacrifice filtering ability and engine protection in the process. OEM filters, which are usually made of paper, filter adequately but at the expense of airflow. And airflow decreases as these air filters become dirty. Not so the K&N air filter. K&N air filters increase airflow without decreasing filtration ability, and the increased airflow remains consistent throughout the filter’s service interval. The secret is in the K&N filter’s construction.
K&N’s initial goal was to develop a filter that would deliver increased airflow during dirty, dusty off-road racing conditions. Increased airflow improves the efficiency of the combustion process, increasing horsepower and torque. But just increasing airflow without ensuring adequate filtration under those conditions would result in a ruined engine. K&N’s solution was a filter design consisting of 4 to 6 layers of cotton gauze sandwiched between two aluminum wire screens. The cotton is then treated with a specially formulated grade of oil that causes tackiness throughout the cotton’s microscopic strands. The resulting K&N filter not only delivers increased airflow while trapping dirt particles that could harm your engine, that level of airflow is maintained even as the filter gets dirty. The layers of oiled cotton fibers in the K&N filter trap dirt particles that are smaller than the holes in the filter media. The thickness of the layers also allows the K&N filter to trap dirt and dust on many levels, trapping more dirt without decreasing airflow. Contrast this with a paper filter that only traps dirt on its surface; as the surface area becomes clogged, the airflow rate goes down.55.46Brand: K&N Part Number: RC-9470 UPC: 024844049568

I ordered a K&N air filter from CARiD and received in 4 days. The fit was perfect and I noticed an increase of throttle response and at least a 2-3 mile per gallon increase on my first tank refill. CARiD is a great company to trust on your vehicle accessories orders. Thank you. Jim Dowis.Was this review helpful for you?

I'm usually sketchy when it comes to buying aftermarket products for my car, especially those that are "recommended" by dealerships. However, after researching K&N filters I decided to buy one. Easy install, instant increase in acceleration. I did notice that the high flow filter does make for more engine noise for those of you who like a quite ride, although I usually drive with windows down and/or radio on so it's not noticeable. Good buy if your looking to spice up your car but it's only a filter so don't expect 5hp increases.Was this review helpful for you?

I simply changed the stock air filter to the K&N air filter and my car just seems better. I'm not sure if it is simply my imagination but it seems faster when I accelerate.Was this review helpful for you?

I've used these filters in other cars and they work great. They pay for themselves in just a short time. Replacing the paper filter twice a year costs more than just one of these reusable, plus you get 1-2 mpg!Was this review helpful for you?

Third K&N filter I've purchased. This one installed just as easily as the first two on my previous cars. On my 2012 Hyundai Sonata, no tools were needed as the airbox is held on by four snaps/clamps. Car feels like it has a little extra get up and go. If nothing else, big money saver over time from having to replace normal air filters with dealers also trying to tack on crazy labor charges too.Was this review helpful for you?
