The AEM 21-836WR 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 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 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 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.

Beef Tallow Sunscreen Stick (Kid-Friendly)
Our family absolutely loves this beef tallow sunscreen stick! It’s become a must-have for park days, sports, vacations, and everyday outdoor activities. The stick format makes application quick and easy, especially when applying sunscreen to active kids who don’t like standing still.
The formula glides on smoothly and feels moisturizing without being greasy. I love that it’s made with simple, skin-friendly ingredients and mineral sun protection, making it gentle enough for sensitive skin. My kids haven’t experienced any irritation, and it helps keep their skin soft and protected even during long days outside.
One of the biggest benefits is how convenient it is to reapply. The stick fits easily in a backpack, diaper bag, or purse, and there’s no messy lotion to spill. It works great on faces, noses, ears, and shoulders, which are often the areas most exposed to the sun.
Why We Love It:
- Kid-friendly and easy to apply
- Gentle on sensitive skin
- Moisturizing with nourishing beef tallow
- Convenient, mess-free stick format
- Great for outdoor adventures and travel
- Mineral-based sun protection
Overall, this sunscreen stick provides reliable protection while keeping skin moisturized and comfortable. It’s a fantastic option for families looking for a simple, natural, and kid-friendly sunscreen that makes sun protection easy for everyone. Highly recommended!

Obsessed with this sunscreen stick!
Just got this Beef Tallow Sunscreen Stick and I'm honestly really impressed! I wasn't sure what to expect since I've never used a tallow based sunscreen before, but it feels so nice on my skin. It glides on super smoothly, doesn't leave a weird sticky feeling, and makes my skin feel moisturized instead of dry like some sunscreens do.
I also love how easy it is to throw in my bag and just reapply throughout my day. The ingredients are a huge plus for me too ofc!
I like that it's made with beef tallow, honey, and beeswax instead of a bunch of stuff I can't pronounce.
I've worn it outside for a few hours already and it held up great. No irritation, no white cast, and my skin felt really soft afterward. Definitely happy with this purchase and I'll be keeping it in my daily routine. Highly recommend if you're looking for a more natural sunscreen option!

Good but very small
The texture is smooth and it smells nice. Definitely way smaller than I was expecting.
