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.\n\u003cbr\u003e\n\u003cbr\u003eWCFAB 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.\n\u003cbr\u003e\n\u003cbr\u003eWCFab 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.\n\u003cbr\u003e\n\u003cbr\u003e\u003ch5\u003e\u003cspan style=\"color: #e42626\"\u003eFeatures:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eUV Resistant\u003c\/li\u003e\n\u003cli\u003eAir Filter Cover\u003c\/li\u003e\n\u003cli\u003ePuncture Resistant\u003c\/li\u003e\n\u003cli\u003eFilters Debris Down To .005\"\u003c\/li\u003e\n\u003cli\u003eHydrophobic Water-Repellent Treatment\u003c\/li\u003e\n\u003cli\u003eResistant To Heat Up To 450 Degrees F\u003c\/li\u003e\n\u003cli\u003eEnhances The Efficiency Of Performance\/Exposed Air Filters\u003c\/li\u003e\n\u003cli\u003eCompatible with WCF100717 4\" Air Filter and WCF100719 5\" Air Filters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003eNote:\n\u003cbr\u003eMaintenance 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.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003ca href=\"\/xtreme-diesel-performance-GAP-product-warranty-availability#warranty\"\u003e\u003cspan style=\"color:#e42626\"\u003e\u003cstrong\u003e\u003cu\u003eManufacturer Warranty*:\u003c\/u\u003e \u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003cbr\u003e\n1 Year\n\u003c\/div\u003e\n\u003cdiv data-hook=\"variant_changed__data\" data-contentsection=\"render_carb_restriction\"\u003e\n\u003c\/div\u003e","brand":"Wehrli Custom Fab","offers":[{"title":"Default Title","offer_id":67655497089244,"sku":"WCF-WCF100728","price":45.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/8288\/2012\/files\/WCF100728_Wehrli-Custom-Fab_1_600x600_c0f36f61-7e68-4804-a6a3-f2a3bd5cd8c9.jpg?v=1791387137","url":"https:\/\/chucksdp.com\/products\/wehrli-custom-fab-wcf100728-outerwears-pre-filter-air-filter-cover","provider":"Chuck's Diesel Performance","version":"1.0","type":"link"}
