The AEM 21-478WR Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Subaru WRX, WRX STI, Impreza WRX and Impreza WRX STI 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 located in the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable textured red powder coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor. The 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 easy to install with commonly available tools and it is backed by AEM's 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.

Perfect Squeaky Toy for My Exes Deranged Dog
Color: Multicolor, Color: Multicolor
My ex-beau and I are still friendly and we exchange Christmas presents. This year, I wanted to make sure that his utterly nutty and completely bonkers Aussie, Diego, got a new toy so that he has added enrichment in his enclosure. Diego really enjoyed this toy! A perfect size for him and a loud squeaker, which my ex will undoubtedly appreciate being squeaked non-stop while he is trying to game with his various assortment of video game people. Worth every penny. Diego’s smiling face is proof of his delight in his adorable Slothicorn. Squeak away, Diego! Squeak away!

A little smaller than we'd hoped but all in all he's pretty cool and our dogs loved him.

Worth it!
Color: Llama
Wanted to keep this for myself! Made well, size is perfect for a 90 pound pup, durable enough for a non chewer (she cleans their fur but doesn’t chew anymore). Durable enough that has been left outside during Summer storms and washed/dryed a couple times already (I use a laundry bag) and still has its adorable shape.
Great value for the money, though I might need to buy another one for myself! *^_^*

Our Doodle's Fav Toy
Color: Multicolor
The first slothicorn toy that we received had a broken squeaker. We were able to quickly and easily get a replacement and send the broken one back. This is one of my pup's favorite toys, although I don't think the horn will last long-- it's the part she likes to chew on the most! At 5lbs, the toy is the same size as my Goldendoodle puppy. I think the toy is overpriced when not on sale (I got on Black Friday promo), so I would encourage waiting for a price drop before purchasing or locating another option that's affordable.
