As such it's still in the box.On a positive note though, it's so big I'm thinking of putting a square of glass on top of it and using it as a coffee table ### ⭐⭐⭐⭐⭐ Excelente producto *by A***I on Reviewed in the United States on 24 July 2021* Muy bueno ## Frequently Bought Together - K&N Universal Clamp-On Air Intake Filter: High Performance, Premium, Washable, Replacement Filter: Flange Diameter: 3 In, Filter Height: 6.5 In, Flange Length: 1.75 In, Shape: Round Tapered, RU-4730 - K&N RX-4730DR Red Drycharger Filter Wrap - For Your K&N RU-4730 Filter - K&N Air Filter Cleaning Kit: Aerosol Filter Cleaner and Oil Kit; Restores Engine Air Filter Performance; Service Kit-99-5000, Multi --- ## 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.kr/products/85669704-k-and-nuniversal-clamp-on-air-filter-high-performance-premium](https://www.desertcart.kr/products/85669704-k-and-nuniversal-clamp-on-air-filter-high-performance-premium) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-15*
