Intake replacement air filter
aFe 24-45505 uses Pro 5R oiled cotton gauze media. Match the exact aftermarket intake, sealing interface and dimensions below before ordering.
Key Features
- Five layers of progressively finer oiled cotton gauze media. Washable and reusable with the correct aFe cleaner and blue filter oil.
- Polyurethane top and base with the flange and top shape specified below.
- This is an oiled filter, not Pro DRY S synthetic media. The oiled media must be serviced with the correct products.
Fitment
| Application | Required checks |
|---|---|
| Specification-matched aFe intake replacement | Universal clamp-on filter, directly cross-referenced by the manufacturer to Volant part 5121. Match the flange, filter envelope and clamp engagement. This does not establish an entire vehicle or intake-system fitment. |
Replacing a filter in an aftermarket intake does not establish a factory-airbox or vehicle-wide fitment claim.

Frequently Asked Questions
Which intake does this filter fit?Universal clamp-on filter, directly cross-referenced by the manufacturer to Volant part 5121. Match the flange, filter envelope and clamp engagement. This does not establish an entire vehicle or intake-system fitment.
Is Pro 5R a dry filter?No. It uses five layers of oiled cotton gauze. The oil is part of its filtration system; do not run the cotton media dry or substitute the oil-free service method for Pro DRY S.
What dimensions should I check?Flange 4-1/2 in; base 6 in; top 4-3/4 in; height 5 in. Match the full sealing interface and surrounding clearance.
What comes with the filter?One Pro 5R air filter and the stainless steel clamp explicitly stated on the manufacturer page. A generic coupler-included field is not an itemized coupling confirmation.
How should I clean and oil it?Use the current manufacturer instructions for Pro 5R. Use the proper aFe cleaner, low-pressure rinsing and natural drying; apply the appropriate blue filter oil without over-oiling. Do not use high pressure, compressed air, high heat or substitute lubricants.
How often should it be serviced?Inspect according to dust exposure, filter condition and restriction. The current general maintenance page gives a 20,000–30,000-mile guide, while the older linked cleaning sheet gives a longer normal-highway example. Neither is a guaranteed interval for this installation.
Does it replace a factory panel filter?This listing is for an intake replacement element. Do not assume factory-airbox drop-in compatibility or reuse unrelated factory-panel installation steps.
Is a CARB EO required for the filter?The manufacturer states this filter does not require a CARB EO number. That does not certify an entire aftermarket intake or establish its vehicle-specific emissions approval.
Installation Instructions
Confirm aFe 24-45505 and the exact intake assembly. Keep debris out of the clean intake, inspect the housing seal and seat the filter using the specified locking or retention interface. Follow the applicable intake manual for access, orientation and any supplied clamp. No numeric clamp torque is established by the current filter page.

Air Filters - Universal Fit
Shop universal air filters for a custom intake, turbo-inlet layout, carbureted air cleaner or compatible crankcase-vent project at Black Ops Auto Works. Compare compact cone filters, large-flange designs, low-profile shapes and complete air-cleaner assemblies to solve the space and connection requirements of your build. Universal Air Filters for Custom Intake Builds A universal filter is selected by dimensions and interface. The flange inside diameter must match the intake tube, turbo inlet, velocity stack, carburetor neck, or breather connection. The filter body must also clear nearby panels, wiring, hoses, heat shields, suspension components, and the hood while leaving enough exposed media for the application. Measure the installation area before ordering. Record the flange size, base width, top width, overall height, filter shape, mounting angle, and straight length available for the clamp. Product titles can look similar even when one dimension makes the filter incompatible. Sh...
