The AEM 21-685C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicles restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Honda Civic SI and Acura ILX models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is relocated to the driver-side wheel well which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engines factory emissions control devices including the mass air flow sensor, a couple replacement silicone breather hoses as well as a replacement radiator hose. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is backed by AEMs Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

    I recommend using the KONG Extreme Dog Toy
    Style: Sport, Size: Large
    Helpful for throwing as much as my dog wants to fetch. I actually had to get a cortisone injection in my shoulder a few months after getting my dog - never had a dog with this much energy before! The Chuckit really helps. Downside: The ball that comes with it is larger than a tennis ball, so may be too much for smaller doge. I can't imagine my sister-in-law's french bulldog carrying it! Also, in our house it gets destroyed within minutes, as my dog is a strong chewer. For this situation, I recommend using the KONG Extreme Dog Toy, Black, size Large. This is shaped sort of like a snowman, which means it bounces unpredictably at times. My dog eventually chews the "head" off of this toy, but the remaining 2/3 still fits in the Chuckit (and is actually easier to throw with the "head" missing!). One caveat: the KONG is significantly heavier than the ball included with the Chuckit, so be aware of that... Also, we ordered our first Chickit in October 2015, then needed to replace it in May of 2017, as it broke. I think the plastic became brittle over that time, as we left it out in the sun & rain in Florida. Since it is cheap to replace, that's not a big deal. (We ordered three Kong toys over that same period of time!) To summarize, it's a very helpful tool to get the ball further, faster, with less strain, than without it. Knowing there are alternatives to the included ball for heavy chewers makes it worthwhile.

    Great Ball Launcher!
    Style: Sport, Size: Large
    Our dogs love this ball launcher! I can throw the ball long distances without any arm strain. The balls wear out, and as described by others, tennis balls don’t fit. Buy extra balls if this is of concern. We bought a few of the “Chuck It” rubber 3” balls and they have worked well for our dogs. It’s a great value and fun for the dogs.

    Chuckit!! Just Chuck it!!
    Style: Sport, Size: Large
    Chuck it further than your skinny little arms can chuck it. Doggo loved this, I loved this and when we were done Doggo promptly hid it under the porch so I couldn’t take it from him. It’s not a squeaky toy, it’s for fetch. You wing it out toward the yard and it flies, bounces if it’s lucky then is attacked in an adoring manner. We like it!!

    Perfect toy for an active dog!
    Color: Large size (7.9")
    My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play. The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing. I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out. Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾
