Extend the life of your air filter with the Wehrli Custom Fab WCF100728 Outerwears Pre-Filter Air Filter Cover from GAP. Wehrli Custom Fabrication highly recommends using an outerwears air filter coveror pre-filter for all WCFab air filters in their turbo kits and intake kits. These pre-filters are specifically designed to deflect damaging debris, which can clog air filters and compromise peak air-flow and horsepower. In addition, by using a pre-filter, you can extend the time between servicing intervals for your primary air filter media, reducing costs and increasing convenience.

WCFAB pre-filters feature uniform micron openings and are run dry. No additional oils or additives are necessary. This dry method prevents dirt from sticking to the oil, which can result in reduced airflow and horsepower. Only particles smaller than .005" can pass through the pre-filter, while larger particles simply fall off. Additionally, these filter covers are constructed with a specially treated woven mesh that repels water without causing any airflow loss. Whether you use your vehicle for everyday driving or hard-core off-road racing, pre-filters are a reliable option to protect and prolong the life of your performance air filter and engine.

WCFab filter covers are treated with a hydrophobic process that helps repel moisture and safeguards against water entering the engine due to puddle splash or heavy rainstorms. However, it's important to note that while their pre-filters are highly effective in repelling water, they are not waterproof. If your intake is submerged, it can hold or pass water. The hydrophobic treatment lasts for six months to one year, depending on usage and conditions. To determine if it's time to replace your pre-filter, you can perform a quick test by spraying water on it with a clean spray bottle. If the water beads off, the water repellency is still intact. If water enters through the pre-filter, it's time to purchase a new cover.

Features:
  • UV Resistant
  • Air Filter Cover
  • Puncture Resistant
  • Filters Debris Down To .005"
  • Hydrophobic Water-Repellent Treatment
  • Resistant To Heat Up To 450 Degrees F
  • Enhances The Efficiency Of Performance/Exposed Air Filters
  • Compatible with WCF100717 4" Air Filter and WCF100719 5" Air Filters




Note:
Maintenance and cleaning of the pre-filter depend on driving conditions and may vary. WCFAB recommend visually inspecting the pre-filter as often as you would normally service your vehicle. For vehicles that are exposed to dirt track competition or dirt road driving, they advise checking the pre-filter after every race or trip. if you notice a significant amount of dirt, it's time to clean the pre-filter. If you primarily drive on the street, they suggest checking the pre-filter every 3,000-5,000 miles. While a thorough cleaning may not be necessary, shaking off any excess dirt is recommended to maintain optimum horsepower and fuel efficiency. Caked debris can be loosened by soaking the filter cover in a mild soapy water solution, then rinsing clean and allowing it to dry before reinstallation. Avoid scrubbing or using aggressive cleaning chemicals, as they can damage the pre-filter and its hydrophobic treatment, resulting in reduced efficiency and premature failure.

Gentle protection for sensitive kids’ skin ☀️
Style: NEUTROGENA SHEER ZINC, Size: 3 Fl Oz (Pack of 1)
I’ve been trying to be more careful about what I use on my kids’ skin, and this sunscreen has been such a good find. It blends better than most mineral sunscreens I’ve tried, doesn’t have a strong smell, and feels gentle on sensitive skin. I also love that it gives solid sun protection without feeling too heavy or greasy. Perfect for beach days, playground time, or just everyday use outdoors. 😊

Worth the price, ?sheer

2021 update: My family has been using this formulation for many years now. I chose it for the high (>20%) mineral content of zinc oxide, because that is the substance responsible for the sunscreen effect of this product. Unfortunately that is also the substance responsible for the white cast on the skin. Other brands typically have mineral content in amounts around 8-12% of the product. So although you may not get as white of a cast with those brands, you are also not getting as much of the sunscreen ingredient either. Another way manufacturers combat the white cast problem is to grind the minerals into ultra-fine particles: nanoparticles. There are downsides to this however: loss of UVA blockage, potential lung damage from inhalation of both manufacturing workers and users, possible coral reef and aquatic life disturbance. So, I expect and accept a mild white cast when using this because it is related to its effectiveness and probable lack of nanotization. When I care about the white cast, I use a drop or two of foundation with it. Otherwise, I leave it alone because after rubbing gently in, it’s not very noticeable. No problems with stickiness or tackiness a minute or so after applying and I’ve never had it sting my or my kids eyes probably because it stays put unlike many liquid formulas. I can also attest to its effectiveness as a sunscreen. We use it in the summertime by the beach and at the lake. In the winter and spring time we use it at 10,000 feet elevation while skiing. If we are going to be outdoors in the sun for any significant period of time, we use it then too. Does the job every time. We are diligent about reapplying after swimming or sweating. The pics I posted for comparison of stick sizes. Now go have fun in the sun...after putting on your sunscreen. ----------------------------------------------- Original post: My kid's skin is sensitive to chemical sunscreens so I get only ones made with mineral sunscreens. Sticks are much easier to apply on the face; less mess and hassle. The price of this large stick was off putting at first, but I got it because of the value in price per product; see pics. Very happily, I find it easier to apply than the smaller sticks. Takes less time to swipe on the face and anyone who has ever tried applying sun screen on the face of a child knows, less time to apply is a huge bonus!!! Same effectiveness in preventing sun burns as the smaller versions. I'm buying another one now.

It works great
Style: NEUTROGENA SHEER ZINC, Size: 1.5 Fl Oz (Pack of 1)
Bought this numerous times for ease of use and how good it works. After countless summer days at the zoo, park or amusement park this is the best at staying on and protecting our kids skin. They do have sensitive skin and it does not irritate it either. Will continue to buy!

Keep it in a cool environment or else
Style: NEUTROGENA SHEER ZINC, Size: 1.5 Fl Oz (Pack of 1)
I think it’s great for kids and I’ve used it and rebought it for years but my only complaint which I’m surprised no one mentions is if it’s warm out, the sunscreen stick melts quite easily in your bag or car and then the stick softens and falls off the applicator making it pretty unusable. Also similarly, if a child pushes the stick out too far, it’ll fall off the applicator. So that wastes a lot for me every time!

No more sunscreen in our hair!
Style: NEUTROGENA SHEER ZINC, Size: 1.5 Fl Oz (Pack of 1)
The only kids sunscreen stick I've found that actually glides on. After struggling with too-hard sticks and messy lotions, this is so easy to apply to my wiggling toddler. And the large size makes application to the whole body a breeze. This is perfect to keep in the diaper bag and quickly reapply for the whole family.
