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.

Each K&N air filter is custom designed to fit into your existing factory air box. 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. By the way, check the CARiD reviews and read what the customers think of K&N porducts.

Love!
Size: 10, Color: Sailors Red
The quality is excellent. They are more of a faded red. I ordered a 10 worried they might be snug but that was a mistake. I should have stuck with my normal size 8. (I purchased an Amazon brand of this style that runs small and the size 10 feels more like an 8.) I love the length-not too short and not too long. They are sturdy cotton. There is not any stretch to the fabric. I’m giving them to a friend. I actually tried to shrink them by washing them in hot water and hot dryer but it didn’t make them fit me any better. Since they were already too big, I can’t really say if they shrunk by doing this. They weren’t huge on me before washing and seemed to fit the same way after. I tried wearing them all day and they seemed to loosen up even further. I was continuously pulling them up. I really feel like the sizing is accurate and you can be pretty confident of ordering your regular size. I’ve already reordered the size 8. I’ll update my review if there any issues with that size.

Unattractive but well made
Size: 4, Color: Sand
The style was unflattering overall. The shorts fit well in the waist, legs, and seat; they just made me look masculine which is not the look I was going for. For reference I am 5’7, 135#, and purchased a size 4 (which again, fit me well). I’m not sure if the issue was the length, or maybe they just down have a flattering cut - they are very boxy and hide any curves I have. 3 stars because the fit was good and they are well made. But just not attractive.

Nice design Size runs big
Size: 4, Color: Nautical Navy
The size 4 runs kinda big. It’s a very relaxed fit. I’m 5’8” 140 lbs and I need a belt to keep the size 4 up. Very nice fabric, great cut. I’m happy with them just didn’t expect them to be as baggy.

Stretch out, size down but love the shorts.
Size: 8, Color: Ocean Breeze
Love these shorts. My favorites ever. I always always wear a size 8 in shorts. The 8 fit initially, but stretched out so much, I didn’t have to unbutton them to get them out. I bought 3 colors. I finally bought one in a size 6. Perfect fit, even if they do stretch a little. Returning the unworn ones, and replacing with size 6.
