The AEM 21-508R 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 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 red powder coated finish. This air intake system was developed to accommodate the engines factory emissions control devices including the inlet air temperature sensor and a replacement breather 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.

    A Turtle with Big Dreams and Weak Seams
    Style: Turtle
    This toy showed up ready to inspire. A squeaky, crinkly, treat-stuffed turtle with a dream: to enrich my dog’s life and stimulate his gentle mind. What actually happened? My puppy took one look, screamed “GAME ON” in dog language, and unleashed pure chaos. Treats fell out instantly, like the turtle panicked and threw them in surrender, saying, “We give up,” almost immediately. The material for the treat pockets feels like craft day at a preschool; soft, colorful, and never meant for combat. This turtle was built for spa days, not war. Points for concept, charm, and squeaky optimism—but this turtle wasn’t built for the front lines of puppy enthusiasm.

    VERY small toy
    Very SMALL!! Do not buy for a medium or large dog. They could chock on it. Fortunately, my grandpuppy is only 13 lbs.

    Only good for small dogs
    I didn’t pay attention to the size and it’s really little. Thankfully, my dog is small.

    Please read reviews/description before buying
    I specifically had to read reviews/description before purchasing (Both small/large versions) . I had ordered the large for a shih tzu and its still kind of small, but she does enjoy it
