The K&N RD-1460 is a round, straight-flange universal clamp-on air filter meant for custom and non-stock intakes rather than one specific vehicle. Its 4-inch flange opening, 7-inch outside diameter, and 9-inch overall height let you size it against your intake tube or carburetor horn before you buy. The element is built from oiled, multi-layer cotton gauze on a rubber top end, and the manufacturer says the media is engineered to support horsepower and acceleration. Because the cotton media is washable and reusable, you clean and re-oil it instead of replacing it, which keeps recurring costs lower than a disposable paper element on a project car.
Fitment is the main decision point. Since the RD-1460 is universal, there is no vehicle-specific application list, so confirm that your 4-inch opening and available space for the 9-inch height and 7-inch base work with your setup. The manufacturer lists racing vehicles, radio-controlled cars, generators, snowmobiles, and tractors among its intended uses. For upkeep, the manufacturer advises letting the filter dry completely before applying oil, and owners on user forums warn against using compressed air to dry it. Enthusiasts searching for a 4 inch flange round straight air filter, a washable cotton gauze universal clamp-on filter, or a reusable custom intake filter will find this part matches those needs.
No. The manufacturer lists it as a universal filter rather than a vehicle-specific part. Fit depends on whether your intake opening is 4 inches in diameter and whether there is room for the 9-inch height and 7-inch base.
Published service intervals differ, so confirm the recommended schedule with the manufacturer before setting your own. Operating in dusty conditions will generally call for more frequent cleaning.
The manufacturer lists a re-oiling amount of 2.24 oz (66 ml) for this filter.
Because the RD-1460 is a universal clamp-on design, there is no vehicle-specific bracket or kit to match, so the install is mainly a matter of fitting the 4-inch rubber flange onto your intake opening and checking clearance for the 9-inch body. The most important maintenance step is the first oiling. Clean and rinse the element, then let it dry completely before applying any oil, since the manufacturer says not to oil the filter until it is fully dry. Once dry, apply filter oil and let it wick for about 20 minutes, then touch up any light spots until the media shows an even color on all areas. Owners on user forums advise against compressed air for drying, so air-dry the element instead.
