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.

Gentle, Soothing Soap That Really Helps Calm Irritated Skin
This soap has been a great option for sensitive, easily irritated skin. It has a very gentle feel, and the combination of oatmeal and goat milk is soothing without being heavy or greasy. It lathers well, rinses clean, and doesn’t leave that tight, dry feeling that a lot of soaps do. I’ve noticed it helps calm itchiness and redness, especially on dry patches. It’s mild enough for the face but still effective on tougher areas like arms and legs. The fact that it’s all‑natural is a big plus, and it feels safe for both kids and adults. If you’re dealing with eczema, dermatitis, or just generally dry, reactive skin, this is a nice, comforting soap that makes the daily routine a little easier.

Great
Bought the 2 pack for myself and my daughter. Haven't heard back from my daughter, but I like the way it makes my skin feel plus the smell is great. I also like that it's homemade and all natural plus will help with psoriasis &/or eczema which my daughter has currently. I would recommend other to try and if I run out, I would buy more again.
