K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards.- Guaranteed to increase horsepower

Great toy that stands up to tough dogs
Size: 5 Pack
When these toys first arrived and I opened the box I was disappointed. They seemed a bit flimsy and were not what I was expecting Boy was I wrong! My dog lived his new toy and it’s has not left his side. Best of all, it’s a tough little toy that can take a beating and keep going. My dog usually tears through his toys in a matter of hours, and I tried numerous toys over the years. I’ve tried Kevlar toys, toy that claim to be very sturdy, he always destroyed them in a matter of hours. This toy looks flimsy, but it’s soft and strong

Dog toy that lasts.
Size: 5 Pack
I've got a heavy chewer on my hands, so I've basically thrown money away on countless "durable" toys that get shredded in minutes. I was skeptical about these, but the "no stuffing" design caught my eye—at least there wouldn't be fluff all over my living room!
I'm happy to report that these have actually lasted! My dog loves shaking them around and making them squeak.
The crinkle sound is a huge bonus; it really keeps him engaged.
The fact that they're lightweight makes them perfect for a game of fetch, and my dog can easily carry them around.
For the price, getting a whole bundle of these is a great deal. If you're tired of cleaning up toy stuffing, I'd definitely recommend giving these a try.

Not for aggressive dogs but no stuffing is super!
Size: 5 Pack
I've bought these several times but have the attitude that toys are disposable. One of my hounds will drop right through then to pull out the squeaker before losing interest. My other hound wants to love them. Glad there is no stuffing to get all over the house but they will tear quickly.

worth the price !
Size: 5 Pack, Size: 5 Pack
Best toys for our livestock puppies since they have been getting into our outdoor things which isn’t their faults but i figure I would get these small squeaky animals toys and they are obsessed and love playing tug a war with them! They’re super soft, the quality is amazing cause these puppies are tough chew monsters, love the squeaky sound it makes and the patting are suitable as well! Definitely recommend this especially for the price and how fast shipping was !
