The material feels really good as well, not cheap. Not sure why there are so many bad reviews, but if you’re not happy, you’ll know within the first few days, so just return it. No need to burn the product because it didn’t meet your standards or expectations. Again, it was perfect for my setup and I would recommend it to anyone wanting that extra security blanket of protection! Also, I noticed there was a lack of photos and vehicle details so I uploaded several. Now go buy it! ### ⭐⭐⭐⭐⭐ Easy to install *by K***N on August 24, 2023* I just installed both of these wraps on my Q50 and it was so easy to do. The quality look good and only time will tell how they last. My Q50 uses 2 filters and is why I installed 2 of them. No change in performance that I can detect. Living in the midwest and fall around the corner I figured these would help with leaves and other things this time of year. That and a little more protection from water getting into the intake. ### ⭐⭐⭐⭐⭐ Filter wrap, keeps the filter cleaner longer *by S***R on June 25, 2025* Filter wrap my old one wore a hole, perfect fit replacement. ## Frequently Bought Together - K&N RX-4990DR Red Drycharger Filter Wrap - For Your K&N 57S-9500 Filter - K&N Air Filter Cleaning Kit: Aerosol Filter Cleaner and Oil Kit; Restores Engine Air Filter Performance; Service Kit-99-5000, Multi - K&N 4-Inch Round Tapered Air Intake Filter - Washable, High Performance, 3" or 3-1/2" or 4" adjustable fitting --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4375641-rx-4990dr-red-drycharger-filter-wrap-for-your-k-n](https://www.desertcart.us/products/4375641-rx-4990dr-red-drycharger-filter-wrap-for-your-k-n) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
