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.

Exactly as described
Size: Throw XL (50x70 Inch), Color: Navy
I wanted to get the little longer size, to help cover my feet while I sleep, because I sleep in a recliner due to back issues. Wow! The material is super soft, and keeps just at the right temperature of warmth at night, so the material breathes well. The extra 10 inches is a godsend now.. My feet stay warm all night long now. So the fit is perfect! The quality of the blanket is great, I’ve had no problems with it. Although my white watch band is now blue.. so I guess the color likes to bleed a bit. I haven’t washed it yet, but I will wash it either alone or with dark colors, because I believe it will bleed its color a bit in the wash & perhaps in the dryer. Still, with it being so comfortable and soft, I would highly recommend this blanket to everyone!

Buy it. Truly amazing.
Size: California King (102x96 Inch), Color: Black
It's a bit thinner than I thought and comes in a surprisingly small box but that doesn't matter at all because there's so much blanket and it's super soft, it feels like covering up with a cloud. Perfectly warm, perfectly cool and perfect for sharing the bed with a blanket hog (or your dog babies). Folds up nice and tight for storage too which is always a plus. Buy this, it's worth the price forsure.

Soft and cozy, sizing seems a bit inconsistent
Size: Queen (90x90 Inch), Color: Sage Green
I actually ordered two of these blankets in two different colors. We had urgent need to add a bed with all new bedding (medical reasons), so I ordered these blankets in a rush. The quality of the blankets seems good. They are very soft and cozy. Lightweight, yet warm. The only issue is that two blankets that should be identical in all ways other than color are actually not even close in size. No matter how hard I try, I cannot get these blankets to line up equally. I really don't like having one blanket hanging lower than the other, especially now that this bed is just inside our front door where every visitor can see it. The king size quilt should in theory cover this discrepancy, but it doesn't fit correctly (another issue). It also means that the blankets are not equally distributed over me and my husband at night. Other than the size inconsistency, I really like these blankets and think they are good value, plenty warm for Wisconsin winters when doubled up with sheets and quilt.

Soft fuzzy polyester king sized fleece blanket with no static electricity
Size: King (90x102 Inch), Color: Grey, Size: King (90x102 Inch), Color: Grey
I ordered the gray color because it was cheaper than the other colors, but it looks nice. This blanket was actually a lot nicer than I was expecting. It is pretty thick, very soft, fuzzy on both sides, fits the king sized bed, and keeps me warm with little extra weight. It is breathable and doesn't make me sweaty. The price was really very good, better than what I saw when shopping in local big stores. This feels great on the skin, and is much more comfortable than heavy wool blankets or quilts. When folded up it doesn't take up much room. It fits well in the washing machine. One of the best features is that it doesn't seem to generate static electricity even in dry air. In general I don't care for synthetic fibers, but I'm making an exception with this blanket, which stays clean and fluffy after extended use. I've had it 2.5 months with no problems and no manufacturing defects detected. The hem stitching is tidy and strong, very neat. I'm thinking of ordering a smaller one to keep in the car for emergencies and outings. I wish all the colors were a similar low price. I have recommended this blanket to friends.
