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.42.95Brand: K&N Part Number: RC-1637 UPC: 024844264404

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?

Have always used these is all my cars. There is debate whether these affect throttle bodies. I guess it depends on how much you oil them. I have had excellent success with these filters over the years and will monitor MAF sensor for build up to see if the above is true or not. K&N has always been a good product.Was this review helpful for you?

I got the filter very quickly it seemed. Installation was very easy with just removing the old one and putting this one in. I have noticed a little more responsiveness with acceleration and it just seems to run better overall. This air filter is a must if your trying to decide which one to get.Was this review helpful for you?

K&N filters rock - superb quality, ease of installation and always a good value. Last filter you'll ever install. More HP and about 1 MPG more for me on this vehicle (but, have had an increase of 2 to 3 on other vehicles). Excellent product and I would recommend.Was this review helpful for you? YesNo
