aFe 54-11472 is the N54 Magnum FORCE Stage-2 configuration with two pre-oiled, five-layer Pro 5R filters. The supplied molded tube and powder-coated metal heat shield join the retained original intake tubes and front air duct. Current primary names 335i, 135i and 535i applications; the original additional exact-retailer-positive model groups remain qualified below. This listing supplies two oiled filters, not the alternate dry pair.
Current primary names N54 335i E90/E92/E93 2007-2010 and 135i E82/E88 plus 535i E60/E61 2008-2010. The linked manual illustrates 335i E90/E92/E93 2007-2010. Original exact-part retailer-positive 1 Series M 2011, 335is 2011-2013, xi/xDrive groups and Z4 sDrive35i 2009-2016 / sDrive35is 2011-2016 remain preserved, including existing bounds and gaps. The narrower current primary/manual headings do not establish physical incompatibility for those retained rows; actual N54 engine, body and inlet arrangement must be confirmed. No N55, four-cylinder Z4, diesel, additional X6 group, earlier or later model year is newly inferred from a generic related-engine or broad retailer widget.

The shared bill lists two dry 21-90054 filters as an alternative for the dry kit; they are not additional selected contents. Use the filter clamps shown and described by the exact procedure; the bill supplies no separate new OE-connection clamp sizes or couplers. Original intake tubes, grommets, vacuum line, front duct and vehicle clamps remain in use. No MAF sensor, sensor transfer hardware, ECU module, new vacuum hose or extra tube assembly is listed. The manual illustration identifies three transferred housing grommets.
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
Two 24-90054 five-layer oiled filters, one molded tube, one housing, one M6 hex screw with flat and wavy washers, and two seal trims. The dry-filter pair is an alternative, not extra contents.
Are both original intake tubes retained?Yes. Seat the new housing fully and align the supplied assembly with both original intake tubes. No separate replacement tube-to-turbo set is listed.
Does installation require a MAF sensor transfer?No MAF transfer or new sensor appears in this exact manual. It does disconnect and restore the original vacuum line.
What happens to the housing grommets and front duct?Transfer the three illustrated original grommets. The small 11-inch trim seals the front air-duct opening; the 30.5-inch large trim fits the housing edge.
How should the filter clamps be shaped?Form them to the oval openings before tightening. The exact manual warns that overtightening can damage the filters or tube; it gives no numeric torque.
Why are 1M, Z4 and later 335is rows retained?Exact selected-part retailers support the original groups even though the primary/manual headings are narrower. Their original bounds remain conditional on the actual N54 body and inlet arrangement; no related-engine expansion is inferred.
Does the dyno report prove 27 hp and 34 lb-ft?It shows stock-versus-prototype run peaks differing by 13 hp and 22 lb-ft on different dates. It does not independently establish the advertised point gains or a matched production-kit result. No flow report verifies 98%.
What emissions, battery and recheck restrictions apply?Current manufacturer states not CARB exempt with California purchase/use restrictions. Follow negative battery disconnection and restore original supports and battery after work. No mileage interval or numeric torque is supplied.
Verify aFe 54-11472. Read all 12 pages and identify the two selected oiled filters, tube, housing, M6 hardware and both seal trims. Work with a cool engine and follow the negative-battery disconnection instruction. Disconnect the original vacuum line and move it back, release all five airbox-lid clips and remove the lid and original filter. Pull back the rubber mount attached to the battery cable to expose the rear intake clamp; loosen that clamp and the front intake clamp. Pull the front scoop duct away from the airbox, then lift and work the original airbox free of its rubber grommets. Transfer the three illustrated original grommets to the new housing. Assemble the supplied tube and housing with the one hex-head M6 screw and both washers. Fit both seal trims, with the small trim at the front duct opening. Seat the new housing fully on the mounts and align its outlets with both original intake tubes. Install both filters, forming their clamps to the oval openings and avoiding overtightening. Reinstall the vacuum line and confirm all connections are tight. The final sequence does not separately describe restoration of the battery-cable rubber mount or battery connection; restore original retained supports and the battery after work using the vehicle service procedure, and confirm the original tube clamps and duct connection are secure. No numeric torque or mileage recheck interval is provided.
Current exact primary, all 12 manual pages, the complete A1/A2/B-H bill, figures A-F and the actual linked dyno report were reviewed. Two five-layer oiled filters are selected, not a dry pair or four-filter bundle. The original intake tubes remain; supplied housing and tube replace the stated factory airbox components. No MAF transfer is instructed. Original exact-retailer-positive model groups and bounds are retained without new engine, body or year inference. The linked report compares stock intake on February 27 with a prototype tube/housing on March 17, both in fourth gear; it was printed August 1, 2008. Its maximum table shows power 227 to 240 and torque 239 to 261, differences of 13 hp and 22 lb-ft. Those are differences between run peaks, not verified gains at one engine speed and not independent validation of advertised 27 hp / 34 lb-ft. Full vehicle identity, matched conditions, correction and selected production filter configuration are not established. No flow report is linked for the 98% claim. Current primary California restriction takes priority over interpreting the old race-only sheet as a street exemption. Manual omissions about final battery and cable-support restoration are qualified. Turn14 authenticated exact-product access remains unavailable. Pricing and protected commercial fields remain unchanged.
