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.33.03Brand: K&N Part Number: RU-1880 UPC: 024844010476

The K&N filter is a good product my car is able to breath a lot better, and it's able to accelarate a lot quicker. I also put a throttle spacer and it gave my car a 6-10 horse power.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?

Simply Put ... My Gas mileage increased by 3 MPG after installing this air filter. I wasn't expecting it and was surprised by a jump from 25.7 and 24.7 mpg before... to 29.6 and 28.5 after install. The previous paper filter didn't look dirty at all and I felt bad doing the replacement at the time because I assumed I had a lot more miles left in the old filter.Was this review helpful for you?
