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.

Might Need to Turn Off Security Measures in Order to Download
I'm a 1st grade teacher and use my ET-2800 religiously. We own 4 of them, between home, my husband's and my classroom, and one for sublimation. I've printed over 15,000 copies on my school printer in the last few years and had no idea about the ink pad replacement until the error message popped up and wouldn't work anymore. I originally purchased a different set and couldn't get it to work. I was in panic mode so I ordered this set, which also originally didn't work. After really paying attention to the alerts that were popping up, I finally had to Google how to turn off my McAfee and Windows Security programs. They were blocking it from running. Once I did that, it was able to install and it is back up and running again. It did make me very nervous to turn them off but as soon as I got it installed, I turned them right back on and ran scans. So far I haven't had any issues in the last few days. The installation is extremely easy, it came with gloves, a screw driver, etc. Mine wasn't messy, so I didn't need the gloves or anything. It's also a 3-pack, so I left myself reminders for next time on how turn off the security. If you are having installation problems, turn off all of your malware security and that will probably help. Just make sure you turn it back on and run scans, the whole process with all of these websites seems shady and scary at first, but this one appears to be legit. I did read that Windows 10 and 11 tend to block sites that are deemed safe.

Recommend without hesitation
I don't typically write reviews but wanted to let people searching for a solution to this Epson inkpad problem that they should not hesitate to order this product. I got it yesterday and had my printer back up and printing in 10 minutes--Epson wanted me to buy a new printer or hire a certified repairman! btw, I did not see what others referred to as a sketchy website for downloading the software and I did not need to disable my antivirus software to complete this task.
