aFe 54-12948-B is a vacuum-formed ABS cover for the installed aFe Stage-2 intake housing used by 51-12942-B and 54-12942-B on qualified 2017-2019 Ford F-250/F-350 Super Duty 6.2L V8 trucks. One cover snaps onto the matching aftermarket housing after removing its trim seal. This is an intake accessory; the factory airbox and unrelated aFe housings are not established mounting applications.
The current exact manufacturer description and eight-page manual identify 2017-2019 F-250/F-350 Super Duty with the 6.2L V8, conditional on the matching installed aFe Stage-2 housing. The two original model-level ranges extend from 2017-2018 through 2019 with original coverage preserved. Model-year collection placement alone does not establish compatibility with a factory airbox, another aftermarket intake or a diesel application. Indexed selected-part retailer coverage through 2021 remains a later-year source exception without extension beyond current primary/manual 2019; no named trims or gasoline-engine alternatives are invented.

The exact bill contains one cover only. No filter, coupling, intake tube, housing, sensor, wiring, screws or other mounting hardware is itemized, despite generic product-page inclusion flags. The complete intake systems and filters illustrated under related parts in the manual are separate products. Retain the removed trim seal for future use; the installation step removes it before fitting the cover.
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
One vacuum-formed ABS cover, service component 05-12942B3. The intake system, filter and coupling are separate and do not appear in the exact cover bill.
Which installed housings does it fit?The current manufacturer identifies 51-12942-B and 54-12942-B Stage-2 intake kits. Match the actual installed housing; a vehicle-only lookup is insufficient.
Does it install over the original factory airbox?The exact application is the listed aftermarket Stage-2 housing. No factory-airbox installation is established by the supplied sources.
Should the trim seal remain under the cover?No. Figure A specifically instructs removal of the trim seal before fitting the cover. Retain it for future use.
What is the correct cover seating sequence?Engage the three tabs first, then align the two holes over the housing dimples as Figure B illustrates.
Are tools or new mounting screws required?The exact manual lists no tools and bills no additional fasteners. No cutting or drilling is specified.
Does the accessory approve the complete intake for California use?No parent-system approval follows from the current cover page's no-EO-required statement. The older manual contains conflicting competition boilerplate; verify complete intake requirements separately.
Are a torque or mileage recheck specified?No numeric torque, battery step or mileage interval appears in the exact cover procedure. No flow/dyno or quantitative sound test is supplied, and later retailer-year coverage remains qualified.
Verify aFe 54-12948-B. Read the complete eight-page manual, work on a cool engine and verify the installed intake housing against the exact current parent-kit compatibility. Remove the trim seal from the top of that housing. Slip the cover's three tabs into place first, then align its two holes over the housing dimples until properly seated. Verify secure fit. The manual lists no tools and no additional fasteners. It provides no battery-disconnection step, numeric torque, cutting, drilling or mileage-based recheck; no interval or clamp torque is borrowed from the parent intake.
The exact current product page and all eight pages of its own manual were read; both contact sheets, the one-component bill, Figures A-B, related-parts page, warranty and contact page were visually inspected. Current accessory page says this product does not require a CARB EO. The older manual contains generic California competition-only wording; this conflict is qualified rather than converted into an approval for either complete intake kit. Existing protected tags remain unchanged except the proven fitment-year correction. Manufacturer noise-reduction and no-power-loss descriptions lack a linked quantitative test; no standalone power, torque, airflow, sound-level or fuel-economy figure is certified. Later retailer 2021 coverage is held for exact housing/year confirmation. Turn14 exact-product information remains unavailable without authenticated access. Protected commercial data and price are unchanged.
