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.

Great chew toy
Size: 10.5 inch Rubber Flex Tread
This is my second time buying the Tonka rings. My dog loves this chew toy. It does take him a bit to destroy them. I give this toy to him as a reward otherwise it be destroyed in 3 days. I have a pitty. So other dogs it should last longer. They are shin whackers and hurt when they connect. So I make sure to watch the dog and toy around small kids and elderly to be safe. They are heavy and made well.

Finally a toy we can leave out!
Size: 10.5 inch Rubber Flex Tread, Size: 10.5 inch Rubber Flex Tread
There are very few toys that we can leave out for our 11 month old golden. Which is a shame because as a small puppy, we taught him to bring us a toy to initiate play instead of nipping. Ropes or stuffies never lasted more than a few minutes so they always had to be taken away. One time he brought us a benenbone to play tug. So I tried this as a last resort. Finally something we can keep out for him! It’s not completely indestructible. He has figured out how to pull bits of tread off. But he chewed hard on it for a solid 20 minutes and it’s still intact with the exception of a few small tread pieces. Can’t say that for 99% of the other dog toys on the market! UPDATE: OK, so it's definitely not indestructible. After a few days of dedicated gnawing, he has almost chewed through the yellow ring so we can't leave him too unsupervised with it. I'm still going to leave it as 5 stars since it's the best tug toy that I have found so far and we have tried a lot! I may buy another one and just make sure I don't let him freely chew on it for any length of time.

Really wanted this toy to be better...
Size: 10.5 inch Rubber Flex Tread
I got this toy because I have 3 large dogs that all like to pull things. I can't always play with them even though they follow me everywhere wanting to play, so I saw this toy and thought it would be good because it would give them something they can tug away at with each other. I saw the thick rubber and thought it would last awhile, but I was wrong. My German Shepherd and Pyrenees mix chewed though the first tire rather quick, and before I realized, I was finding chunks of tire around the house and yard. Thankfully, none of them tried to eat it. It seems like it could be a good toy for an aggressive chewer IF they are smaller and not as strong as these large dogs are, but it did not hold up long to mine.
