Momentum HD replacement filter with reinforced metal wrap. Current manufacturer base/top dimensions conflict: 8 inches in the headline versus 8-1/8 inches in the detailed paragraph. Confirm the actual revision and housing clearance. The detailed paragraph specifies 70 pleats with 20 mm pleat depth. No exact intake-system part number or top/base material is named.
Is Pro 10R a dry filter?No. It uses ten 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 6 in; base Manufacturer headline 8 in; detail 8-1/8 in β verify revision; top Manufacturer headline 8 in; detail 8-1/8 in, inverted β verify revision; height 9 in. Match the full sealing interface and surrounding clearance.
What comes with the filter?One Pro 10R air filter. A separate supplied clamp or coupling is not confirmed by an itemized contents list. 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 10R. 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. Follow the current instructions for the installed Pro 10R filter; actual dust exposure and restriction determine service needs. No fixed mileage interval is established by the current exact filter page.
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.
Confirm aFe 20-91059 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.

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...
