Frequently Asked Questions
How often should I clean and re-oil this filter?Under normal conditions, clean and re-oil your aFe Pro 5R filter every 30,000 to 50,000 miles. In dusty environments, inspect it more frequently. Always use aFe Power's dedicated cleaning and oiling kit for proper maintenance.
Will this filter increase horsepower over the OEM paper element?Yes. The 24-91040 flows significantly more air than the factory disposable paper filter, allowing the engine to breathe more freely. In combination with a full intake system, gains are more pronounced, but a filter upgrade alone delivers measurable improvement in throttle response.
Can I over-oil this filter and damage my MAF sensor?Yes, it is possible to apply too much oil when reconditioning a wet-media filter. Always apply oil lightly and evenly, allow it to wick for 20 minutes, and blot any excess before installation. The Pro 5R .
Does this filter fit my factory airbox without modification?Yes. The 24-91040 is precision-molded to the exact dimensions of the OEM filter element. It drops directly into your factory housing and seals against the factory airbox lid without any trimming or modification.
How does a reusable filter compare to replacing with a new OEM filter?Over a typical ownership period, a reusable aFe filter costs less to maintain than buying replacement OEM paper filters every 15,000 to 20,000 miles. It also consistently outflows the OEM element throughout its service life rather than degrading as the paper loads up with debris.
Will this filter void my factory warranty?Under the Magnuson-Moss Warranty Act, a dealer must demonstrate a direct causal link between your aftermarket filter and a specific failure to deny a warranty claim. A high-flow air filter cannot be used as a blanket reason to void your powertrain warranty.
Is this filter compatible with a cold air intake tube?This is a drop-in filter designed for use in a factory airbox. If you are building a full cold air intake, aFe Power offers intake systems designed around their filter canisters. Contact us to find the correct intake system for your build.
What is the warranty on this air filter?aFe Power provides a limited manufacturer warranty on materials and workmanship. As a reusable filter, warranty claims related to improper cleaning or oiling are excluded. Contact aFe Power or us for current warranty documentation.
