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.

This is SO helpful for Dyshidrotic Dermantitis
Size: 6.76 Ounce (Pack of 1)
I have dyshidrotic dermatitis and this helps me with the dryness and itchy feet. It is pretty greasy but I have to keep socks on so I don't care. It works the best if you use it twice a day but still works well once a day.

A rich moisturizer that doesn’t feel heavy!
Size: 13.5 Ounce (Pack of 1)
I bought this because the skin on my face is very reactive and has also been very dry and I wanted to try something that was a little more rich than the moisturizer I was using. I liked that this is for face and body so it comes in a bigger size than typical face moisturizers come in. I have been using it for about a week and have noticed a reduction in flakiness and my sensitive skin does not get irritated by it. It absorbs really well and doesn’t feel heavy or make my skin feel sticky. I definitely feel it is worth the price since you get so much in the bottle and it will last a very long time!

The best eczema cream I’ve used !!!
Size: 6.76 Ounce (Pack of 1)
I will give 10 stars if it were available!! Used most of the eczema creams out there, including prescribed ointments, but given the fact you can’t avoid using water on your hands throughout the day, the eczema was only getting worse for the past couple of months! I am glad I didn’t give up and found this cream!!! The second I put this cream on my hands, it immediately moisturized the itching and flaking skin without drying or being greasy unlike other creams I’ve used before. It’s very calming, soothing, and deeply moisturizing! So I had to write this review for those who are suffering the similar symptoms. This may help you as much as it is helping me as I speak!

Seems to work for damaged barrier (accidental damage as well as eczema and rosacea).
Size: 6.76 Ounce (Pack of 1)
SO I am currently tryign to repair a damaged skin barrier. I have both rosacea and eczema so it's nearly impossible to find a product that makes both conditions happy. I started out using the cream version of this but my face always felt dry with it. I decided to try this since a balm usually helps keep in moisture much better. I am only using a gentle cleanser and this, planning on adding in a toner at some point. At first I thought I was sent the cream again because this comes out like their cream version but as you rub it to spread, you can tell it has a thicker feel to it. It spreads easily and doesn't tug at my skin. Seems to sink in pretty quickly but it does leave a sticky film until it completely absorbs. I can feel my eyelids stick while waiting. Not sure how long it takes to fully absorb because once it does on my eyelids, I forget. But the stickiness does go away and leaves a soft texture behind. I do find some itching in places I normally get when my skin dislikes an ingredient. But I'm not sure if it's my normal or current damaged barrier. It helps with the dry feeling and I would say I only feel a slight tightness. But so far, the best moisturizer I have used. And I love that there is NO NIACINAMIDE, NO HYALURONIC ACID, no oat, no shea butter, and no cica/centella asiatica. These ingredients wreak havoc on my skin and everybody is adding this to everything. It's been so hard to find a moisturizer.

Works quickly to calm itch
Size: 6.76 Ounce (Pack of 1)
I had an itchy outbreak on the back of my hand the day this product arrived. Perfect timing. Applied Avene and within a short time the itch calmed almost 100%. Slept through the night and this morning, the red rash is about 95% healed. So glad I bought this. Just another old age issue to deal with.
