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.

Awesome enrichment toy!
Size: Large, Color: Green, Size: Large, Color: Green
These are awesome! My dogs love them and keep them occupied for 30-60 mins so I can make and enjoy my coffee in peace before work. They are very easy to clean, but as others have mentioned, they can get stuck. I had to take a pliers to get one of them unscrewed. Hopefully that’s not a constant issue. I do wish they were more durable since there were a lot of teeth marks in them after the first use, so I upgraded to the black super chewer one. I’m happy I gave these a try and feel they are worth the money, especially for high energy dogs who get bored easily.

Best toy/treat! (Use oil on inner screw to open)
Size: Large, Color: Green
My dogs love these! This gives them a dedicated 20-40min of dog joy. They often get up halfway thru and switch but whatever makes them happy. They do get STUCK! And can be impossible to open. I now use a dot of olive oil on each level of the screw and then twist it in and out a couple times to distribute the lube so its possible to open when they are done. I find it very important to collect them immediately when they are done and open back up for cleaning. Do not let them dry as it will be very difficult to open.

These are must haves for dog owners!
Size: Large, Color: Pink
These things have saved my sanity! I have two dogs and we use these at least two to three times per week. They are high quality and last thru heavy chewers. We spread peanut butter inside for a quick treat when clipping nails, or make our own mix of Greek yogurt, dry oatmeal, diced carrots, a little pumpkin, and a bit of diced apple, mix it up and freeze it in the Pupsicle mold. That way we have a bunch ready to go and aren’t buying expensive refills. The colors are adorable, the pupsicle is durable, and the dogs LOVE them. FYI - it’s a good idea to use a little olive or avalado oil on the threads when closing them up - it makes life so much easier when screwing then on and off. We throw ours into the dishwasher.

Like unto the Holy Grail of food toys. [I recommend buying the separate treat mold, too.]
Size: Large, Color: Green
So far, I have no complaints. I can see that this toy might not work well for some combinations of dogs and people, but for my two current dogs (blue heeler and small terrier), this thing, plus the treat mold, is GREAT! I love that the dogs get it more or less fully emptied, and it is washable. I love that I can pre-prepare a whole bunch of frozen fillings by using the treat mold (sold separately). Yes, I agree that this is a very expensive item, especially if you buy the treat mold along with the toy. I bought two toys at a very reduced price on Prime day, also bought the treat mold at full price, and consider the combined purchase a great value at this cost. The current price (for the toy) is comparable to the cost of an extra-large Toppl, and I've seen it at a price similar to the current cost of a large Toppl. I checked the current price of the XXL "extreme" Kong I needed to use for one dog, and the current price on a different web site is almost the same as the Woof Pupsicle. To answer questions and issues I've seen mentioned... * My terrier weighs 16 pounds and uses the large toy with no problem. Possibly it is minimally less thoroughly cleaned out, but I'm not positive about that. My only warning would be that you ought to keep track of calories and/or what you put in it because you could potentially give a small dog way too many empty calories from "junk food." * The toy is still usable without the treat mold. Just fill up the solid half of the toy and stick it in the freezer overnight, same as you would do with a Kong, except it takes up less space. * Do introduce it properly, by initially giving it with NON-frozen and sticky food in it. An even more slow, careful, step-wise introduction may be necessary if your dog is a destructo-dog. * The terrier takes about 20 minutes to empty it of frozen canned dog food. That's non-trivial, and I'm not sure why people are complaining. The heeler takes less time (maybe 15 minutes?), but it's still an amount of time that is helpful for me, and this licking activity seems to be especially calming for her (as compared to using the food puzzle toys with kibble). * It initially was extremely difficult to open and close the thing. I was best able to do it with a "light" touch, not pulling and making sure not to press the two surfaces together. After not very long, it became much easier. I didn't need to use oil. If you have trouble getting it closed, it became a lot easier after the solid part was frozen (while the vented part stayed at room temperature). * I agree with others that a larger version might be nice, but a larger version might make dogs more likely to destroy the toy in place of emptying it by focused licking. * I'm not sure that any of these toys are truly indestructible. People are mentioning Kongs. Well, my Kongs have required periodic replacement. They have tooth marks and eventually get "modified" to where pieces might get torn off and consumed. For one dog, I had to upgrade to the XXL-size Extreme (black) version, and she also put tooth marks in that. I own a fortune's worth of Kongs, Toppls, and a couple similar food toys, and they all have their issues. They have holes in them that allow liquid to immediately come out (before freezing occurs). They are bulky and use up a lot of space in the freezer, and the unusual shapes make them non-stackable. For me, Kong toys are time-consuming to fill and difficult to clean. My dogs couldn't get the very end cleaned out without throwing the Kong around (making a big mess), and even then it wasn't fully clean. Some did end up with mold in that part of them. [It looks like new inventions, like plugs (or something like that), may solve some of the problems; I didn't have those.] I mention the other toys only to say that this unique brilliant toy has seeming solved all those problems, and my dogs truly LOVE this toy as well. Be assured, I will update this review if anything changes.

Perfect for Our Nervous Rescue Dog
Size: Large, Color: Green
First Impressions I bought the Pupsicle for our new rescue dog who was very nervous whenever we had to leave the house. Right out of the box it felt sturdy and well-made, and I liked that it wasn’t just another cheap chew toy. ⸻ Setup & Ease of Use I went with the premade treat inserts to start, which made it super simple — just pop one in and hand it over. It’s also dishwasher-safe, which is a huge win for me since I don’t want to deal with scrubbing peanut butter out of toys. ⸻ Performance in Real Life She loves it. The Pupsicle has kept her occupied and calm, which has really helped her acclimate to her new home. Instead of pacing or whining when we leave, she settles down with this toy and stays busy. ⸻ Pros & Cons Pros: • Helps reduce anxiety for nervous dogs • Very durable and solid • Easy to clean (dishwasher safe) • Premade inserts make it effortless Cons: • On the heavier side, so probably best for medium+ dogs • Inserts are convenient but add a little extra cost ⸻ Who It’s For Perfect for new dog owners, rescues, or anyone with a dog who needs a healthy distraction when left alone. ⸻ Final Verdict The Pupsicle has made a noticeable difference for our rescue pup. It’s durable, easy to use, and has genuinely helped her feel more at ease in her new environment. Highly recommend.
