Quantum Pro Dry S Oval Tapered Gray Air Filter (21-90103) by aFe. Quantum Pro DRY S air filter by aFe Power is specifically designed for the Quantum Series cold air intake systems and feature an injection molded base and top for lighter weight and rigidity. The newly designed base includes a built-in, 3-angle velocity stack for smooth, even airflow. The Quantum Pro DRY S filter is a 360-degree radial flow air filter with oil-free, 3-layer progressively finer porosity synthetic media for optimum flow, filtration and convenience. Captive screws are included to eliminate lost hardware and to securely fasten to the Quantum Intake system housing.

Oil impregnated air filters offer great performance and extended service intervals, but when service is required they can be time consuming, waiting for the filter to dry after cleaning and then applying the oil. So if minutes are precious to you there's a performance air filter for you, the Pro DRY S. The Pro DRY S was developed specifically to provide increased airflow and excellent filtration efficiency, in a filter package that could be washed and put back into service in a minimal amount of time.

The Pro DRY S filter contains 2 layers of randomly porous synthetic fabric. This allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.

The pleats in the Pro DRY S are evenly spaced for greater dust holding capacity and the tips are rounded for better airflow. They're also 30% deeper than comparable aftermarket air filters for longer service intervals and greater dust holding capacity. The sealing surface and supporting structure of the Pro DRY S are made from 100% polyurethane, to withstand extreme engine temperatures. Flat panel filters are constructed with 4 sides, not just 2, for added rigidity and seal support, and feature a progressive bump seal to ensure an airtight seal.

Under normal driving conditions the Pro DRY S won't need servicing for 25,000 to 30,000 miles. Since a typical OEM paper element should be replaced every 15,000 miles, the Pro DRY S will pay for itself before the first service is required. And when service is required, the Pro DRY S can simply be washed and dried and put back into service; no oiling is necessary. The synthetic filter media dries in far less time than cotton gauze so your downtime will be kept to a minimum. The Pro DRY S can be washed and reused repeatedly; you'll never have to buy another air filter, ever.

Direct factory replacement Pro DRY S air filters are backed by a limited lifetime warranty. Universal clamp on filters have a 2-year warranty while racing filters have a 1-year warranty.

It’s not your average toothpaste consistency
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1), Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
My teeth have become a little sensitive recently so I started using Sensodyne. Through some research, I discovered hydroxyapatite. I was extremely excited and intrigued at the idea of its ability to strengthen tooth enamel so I just had to give it a try. I first started with Risewell, but then my dentist recommended David’s due to it having nano-hydroxyapatite. I really like this toothpaste. As you can see, it’s almost all finished. I like the flavor, I like that’s it’s fluoride free so you can swallow it, and it’s made in the USA. I’m obsessed with the packaging too! It’s got a very minimalist and modern aesthetic and it comes in a recyclable metal tube. I also love that it comes with with a little metal key to help push put all the toothpaste. I definitely felt like this toothpaste improved my teeth sensitivity as well as helped whiten my teeth. I love that it’s so convenient to order on Amazon so it ships quickly (as opposed to Risewell). If you’re not familiar with hydroxyapatite toothpastes then you may be surprised by the texture. It’s very loose and watery. It doesn’t really lather up the way toothpaste does. I feel like that’s one nuisance with using these natural toothpastes, but I would also say that the benefits of using it outweigh that. Overall, this is a solid product and I will definitely continue to use it as well as recommend it to others.

Good product.
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
This is a little different texture from regular toothpaste and it doesn't lather in your mouth. However, it seems to clean really well, and taste is fine.

Gentle, Effective Toothpaste That Leaves My Mouth Feeling Clean
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
I bought Davids Fluoride-Free Xylitol Toothpaste because I wanted a natural alternative that still supported whitening and enamel health, and it has become my go-to daily toothpaste. I use it morning and night, and the peppermint flavor is refreshing without being overpowering, leaving my mouth feeling clean and energized. I noticed my teeth look brighter after a couple of weeks, and my gums feel healthier and less sensitive compared to when I used regular fluoride toothpaste. I love that it’s free of sulfates and harsh chemicals, and the texture is smooth and easy to apply to my toothbrush. The sleek, eco-friendly packaging is a bonus, and it feels good to use a product that aligns with both my oral care needs and my values.
