aFe 54-10462 is the Magnum FORCE Stage-2 Pro 5R intake for the 2001-2006 BMW M3 E46 3.2L. It includes one five-layer oiled filter, molded intake tube, metal heat shield and a separate flow divertor. Transfer the original MAF sensor using the specified gasket and the correct hardware for the actual kit revision.
Current exact primary identifies BMW M3 E46 2001-2006 with the 3.2L engine. The existing Base application remains 2001-2006. Older 2001-2007 wording does not establish a 2007 application or coverage for another chassis, engine or Z4 M. Confirm original sensor, controller clearance and mounting arrangement. The manufacturer cites D-550-38, and the indexed official table identifies the 2001-2006 M3 3.2L; full order conditions and exclusions remain unverified.

Only one selected oiled filter is supplied. Dry-media references in the shared sheet are alternatives. The flow divertor is included and must be installed. Step 14 mentions MAF spacers, but the bill omits them; confirm actual supplied quantity and dimensions before installation. The sheet lists T20 tooling as provided, outside the component bill. No separate top cover or new MAF sensor is listed. Do not infer screw pitch from the ambiguous printed M4 designation.
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 oiled filter, molded tube, metal heat shield, flow divertor, straight coupling, two clamps, MAF gasket, mounting and sensor hardware, and trim. Confirm the unlisted sensor spacers against the actual revision.
Is the flow divertor optional?The exact sheet includes it and instructs installation with two M6 x 1 x 10 button-head screws.
Is the shield plastic or metal?The shield is powder-coated metal and the intake tube is molded plastic. Current primary text conflicts on 16 versus 18 gauge.
Are the MAF sensor spacers fully specified?No. Step 14 calls for spacers, but the bill omits their quantity and dimensions. Verify the actual kit before transferring the original sensor.
Which sensor screws are supplied?The bill prints M4 x 7 x 16 cheese-head slotted screws. Verify actual thread pitch and sensor fit; do not force ambiguous hardware.
Does older 2007 wording establish another application?Current primary and the existing application cover the 2001-2006 E46 M3 3.2L. Another year, chassis or engine requires separate exact proof.
Are the advertised gains and emissions conditions verified?The linked chart lacks a complete comparison legend and test conditions, no flow report is linked, and full D-550-38 conditions remain unverified.
What final checks and recheck apply?Secure the filter, sensor connection, housing mount and moved headlight controller with its cover. Recheck connections and filter after a few hours. No battery step, numeric torque or mileage is stated.
Verify aFe 54-10462. Read all fifteen illustrated steps and the complete bill. Unplug and protect the MAF harness, remove the front snorkel and upper airbox, and retain the latter for sensor removal. Release the headlight-controller cover tabs, remove its two 10mm-tooling bolts and move the controller to free the lower airbox. Save the remaining lower-airbox mounting bolt for the new shield. Remove the original rubber mount below the box and the accordion coupling. Apply trim and position the new housing without tightening it. Slide the straight coupling onto the tube, pass the tube through the housing and align its two flange holes with the supplied M6 hardware. Install the flow divertor with its two button-head screws. Transfer the original MAF using the gasket, correct screws and the revision-appropriate spacers; the bill does not establish spacer quantity or dimensions. Compare the final filter arrangement with the illustration. Before operation, ensure the filter is secure, the sensor is connected, the saved housing mount is tightened and the moved controller, its bolts and cover are safely restored. These final restoration details are not separately numbered in the sheet; resolve any fit or hardware discrepancy before operation. Follow the illustrated front-inlet arrangement rather than assuming snorkel restoration from another kit. Secure all hoses, clamps and electrical components, then recheck connections and the filter after a few hours. The exact sheet gives no battery-disconnection step, numeric torque or mileage interval.
Current exact primary, the full one-page illustrated manual, all fifteen images and the complete bill were reviewed with the actual linked dyno image. The primary conflicts on shield gauge, and the sensor-screw pitch and unlisted spacers require confirmation against the actual kit revision. No spacer dimensions are borrowed from another intake. Current primary supports 2001-2006; older 2007 wording does not extend the existing application. The linked solid/dashed red and blue curves lack a stock/modified legend, run identity, numerical comparison table and test conditions, so advertised 12 hp and 11 lb-ft are not independently verified. No linked flow report establishes 42%. D-550-38 is cited and the indexed official row identifies this M3 application; full exact order conditions and exclusions remain unverified. Verify applicable emissions requirements before purchase or installation.
