AEM IND Cold Air Intakes

Engine Cold Air Intake Performance Kit

The AEM 21-685P 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 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 chrome-like finish. This air intake system was developed to accommodate the engine's 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 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. View the 21-685P vehicle applications to determine the legal status for each vehicle.

AEM's Performance Cold Air Intake Systems are designed, tuned and dyno-tested to give your engine more power and acceleration by replacing the restrictive factory air filter, air intake tubing and air box assembly.

Works great, just no different from any other pimple patch on the market
These pimple patches by Thayers are made from 100% hydrocolloid and definitely work in terms of helping speed up the pimple healing process. These pimple patches work best when your pimple is ripe enough. If you stick these pimple patches on when your pimples are not ripe enough yet, they will not do anything, and it would be a waste of a pimple sticker. You know when your pimple is ripe when it comes to a head and has that little white spot. When it's ripe, I would stick this pimple patch overnight and typically by the time I wake up, the pimple patch will have absorbed all the gunk from my pimple. You will know that it worked if you see your pimple patch turn white. Sometimes it might take an extra night for the gunk to come out. When you stick these pimple patches on, make sure your face is freshly washed without any face products or else they won't stick as well. Given what the Thayers brand is known for (natural remedies and herbal extracts), I would think that they would infuse some natural ingredients into this pimple patch to help speed up the healing process even more. But to my disappointment, they did not add any additional active ingredient to this pimple patch despite what their brand stands for so I took off a star.

Great for my teen
We love Thayers everything. They work so great and they truly are invisible. My daughter can wear them to school and not even realize they’re on her face.

A MUST Buy for your TEEN.
Helping my son so much - these work within a couple of hours to flatten ouchie whiteheads. My 14 years old son is so grateful! There’s 2 sizes, 22 patches, and they truly are “invisible” like the box says. These have been working so well (better than any other brand - and we’ve tried them all) and the price is the cheapest. We Love THAYERS brand now - lifetime user here for sure.

Different than most on the market worth a try!
I’ve tried a lot of pimple patches and these actually feel different from most of the ones on the market because of the sulfur/OptiMSM ingredient combination. They don’t just cover the spot — they seem to really help bring everything to the surface faster. I had one deep pimple that had been under my skin for so long I honestly started wondering if it was just a scar at that point, and this patch finally helped it come out and heal. The patches are super thin and blend into the skin really well, so they’re easy to wear during the day or overnight. They stick well without feeling harsh on my skin, and I also tried them on my tween sons, who definitely need to wash their noses better sometimes, and they seemed to work really well on their softer skin too without causing irritation. I also love the little travel pouch included. Definitely one of the more effective acne patches I’ve used.
