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.

Fun Dog Toy, Relatively Durable, Looks Great, and Squeaker Isn't Annoying!
Color: Deep Green, Size: 10 IN
This is a fun and well-made dog toy that’s held up better than expected, especially considering my dog usually makes quick work of stuffed toys. He’s not the most aggressive chewer, but he’s definitely skilled at tearing things up over time, and this one is still going strong so far. The plush armadillo design is adorable and comes in a variety of color options, which is a nice bonus. It has your standard fluff type filling, and I really appreciate that the squeaker has more of that low grunting sound (like a pig), rather than a sharp, high-pitched one. It’s much less annoying to listen to during playtime. The 10" size was just right for my 45 lb dog, offering a good size for tugging and carrying around. Comfortable to hold, seemingly durable so far, and cute design. Seems to be a winner, would recommend!

Perfect size, cute, reasonably durable, and my dog loves it.
Color: Pink, Size: 8 IN, Color: Pink, Size: 8 IN
I ordered this for my 2year old, 55lb Staffy Pitt mix. She’s usually pretty rough on toys. She seems to either destroy them after 15 minutes, or, in a few instances, decides that she likes them enough to treat them more gently, in which they last for months or longer. I have no idea how she chooses, but in this case, she pretty much immediately ripped off part of an ear, but then, and since that time, has played and chewed on it without causing further damage. The toy is pretty adorable and looks and feels well made. It’s not constructed with a super durable material like some toys made for aggressive chewers are, but it’s also not marketed as a toy for aggressive chewers, so the material used is appropriate. The fabric feels dense and of a high quality, and the stitching looks to be of a high quality as well. I chose the 8-inch version in pink, and I’m happy with this size. It’s not too big, nor too small, and is easily portable. It arrived smashed up in a small bag, and I thought maybe it would be deformed when I took it out, but it wasn’t. It unfolded right away and then maintained its normal shape perfectly. Happy with this product, and after receiving it, I ended up ordering another, this time the 6-inch version, and while that is also a nice option, I like, and feel that the 8-inch version is a better deal. If this toy continues to last for a few more months, I would order another one, as my dog enjoys playing with it. It’s not her go to toy, but it is one of the few she keeps in playing rotation on a regular basis.

Luxurious Feel, Durable Build… but Full Rotation Privileges Have Been Revoked 💙🦴 🐾
Color: Blue, Size: 6 IN, Color: Blue, Size: 6 IN
🐾 Hi, I’m PVD; toy curator, plush critic & occasional chew sommelier. This armadillo arrived beautifully packaged and immediately met my standards for texture, squeak clarity and cuddle factor. I originally gave it 5 stars for quality; and still do! But today I’m updating the review to reflect my current toy lifestyle rotation. 😌 What impressed me from day one: ✔️ High-end plush feel; soft enough to nap on, tough enough for energetic zoom bites and great relief from teething ✔️ Strong stitching; survived multiple “stress tests” (I chewed with intention) ✔️ HQ squeaker; not tinny or annoying, more of a honk ✔️ 6in is perfect size for small breeds; easy to carry during dramatic hallway walks Why it now gets 4 stars from a seasoned toy collector: ✘ As my luxury toy collection expanded, this one gets grabbed less often ✘ Simple design; I now favor more interactive or complex textures ✘ Still “keep-worthy,” just no longer VIP spot on the chaise lounge Best For: • Pups who enjoy soft comfort toys or emotional support snuggles • Light to moderate chewers • Dogs who like to carry their plushes around proudly • Ideal as a teething toy or thoughtful gift 🚫 Not ideal for: power chewers or highly stimulation-driven pups (like me now; my taste evolved) 📝 Final Re-Barks: Still recommend for pups who love cuddly squeaky companions. Great starter plush and great quality; just know that ultra-picky toy enthusiasts may rotate it out once newer models (or squeakier friends) arrive. — PVD (Plush Aficionado, Toy Rotation Director & High-Maintenance Household Icon) 🐶💁🏻‍♂️✨

Hollypet Gray is excellent
Color: Gray, Size: 14 IN
This GrayHollpet comes down the assembly line that produces a good product. It is tough and stays together Don't buy the brown one, it started to fall apart in less than 30 days. These can be a good product!
