Dry Flow Air Filter 4.0-inch Filter Inlet Size

Boost your performance with the CorkSport 4.0-inch Filter that has up to double the flow of OEM filters. The 4" cone-shaped dry filter is made of synthetic fiber that is water-resistant and reusable. The non-woven media filters and traps dirt and dust without the need for oil. The engine vibrations help make the debris fall off, so the filter lasts longer.

The CorkSport Advantage: 

• Color: The filter comes in dark gray and is a perfect fit to blend in with any build's color scheme.
• Oil-free filtration media: The unique non-woven filter media catches dirt without the need for oil. Plus, the filter will actually shed debris when the engine vibrates, keeping your filter cleaner longer.
• Polymer mineral reinforced internal framework: The filter is extra durable to ensure it retains its form and prevents collapse during extreme vacuum from turbocharged engines.
• Easy Maintenance: Cleaning the 4.0" CorkSport dryflow air filter is simple and easy. Add a little gentle all-purpose cleaner and some warm water. You can tap the filter a few times to remove access dirt from the filter folds. Our non-woven filter media does not soak up water and can be cleaned as often as needed.
• Specifications: The CorkSport 4.0" Outlet filter has a 5.25" filter media length, protrudes 6.61" from the end of the fitting to which it is attached, and is 6" at its largest diameter. Full dimension details are available on request.
