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.

Favorite Daily Moisturizing Sunscreen!
I heard about this product on Dr. Dray's You Tube Channel. She is a great dermatologist that gives excellent recommendations on sunscreens and beauty products. She uses science based research & reputable companies. She is also conscious of product costs and offers budget friendly options to protect your skin. Eucerin is one of her favorites and sunscreen is a daily requirement, not a recommendation if you want to keep healthy skin. I have been on the search for years for a favorite. I kept getting greasy results or a white cast. This one offers more of a moisturizing effect as it has hyaluronic acid in it along side sunscreen to protect your skin. I have never had a white cast from this one. It is not waterproof, but a nice one for daily use and under make up. It doesn't smell or clog my pores. I have used about 4 bottles at this point and plan to keep using this one. It is great! I also use the body sunscreen in the tube as well. I like them both.

Absorbs well; no oily feel. Great sun protection!
I got a sample of this from my dermatologist and loved it so I switched to this brand! It has a lightweight feel, absorbs well without leaving a white cast, and has a matte-like finish without feeling dry. It's similar to Laroche-Posay Anthelios Clean Sunscreen, but is more moisturizing and a lot cheaper! I have rosacea - this sunscreen doesn't cause breakouts. I use the 50 SPF facial moisturizer on my face (duh) and the tube of the 30 SPF on my neck and chest. Great products!

Amores y semiodios
Tengo la piel del cuerpo seca y la de la cara es mixta con tendencia al acné. Decidí probar estos protectores solares, ya que uso productos que dejan mi piel fotosensible. Probé el protector solar corporal y me gustó. Tiene una consistencia bastante líquida, pero se esparce muy fácil. Se demora un poco para absorber, no deja una sensación pegajosa ni grasosa, pero se siente un poco pesado por un ratito. Inicialmente deja un olor algo fuerte e incómodo, que en un par de minutos desaparece. No me expongo directamente a la luz del sol casi nunca, pero no he notado ningún tipo de quemadura y oscurecimiento de la piel, por lo que creo que cumple con la protección solar. En general, me gustó el producto. Otra historia es el protector solar facial. Tiene una consistencia tipo crema, se esparce fácil, no deja residuo blanco, no deja sensación grasosa o pesada. Se absorbe rápido. Pero luego de un par de usos, me brotó la piel del rostro. En cambio, a mi esposo que tiene piel seca en su carita, le ha servido mucho. No le ha generado ningún tipo de reacción adversa y su piel lo aceptó desde el primer momento. Luego de una semana de uso, no tiene ninguna queja al respecto. En fin. Los productos son bastante buenos, pero yo, con mi tipo de piel, no usaría el protector solar facial.

So far we're loving it
Started using this about a month ago. The price for both was cheaper than just the face one at my local store so I decided to try them. I use it for me kids as well as myself and so far it's worked great. It doesn't have an overwhelming smell and doesn't leave a greasy film like some others. My kids used it and then we're outside swimming for about 2.5 hours. They got some color on their faces but we didn't reapply so I wasn't surprised. I was outside during that time too and didn't burn at all (I wasn't swimming) where I had applied it. So far I love it and will continue using.
