aFe 54-11942 is the Magnum FORCE Stage-2 Pro 5R intake identified by aFe for the 2006-2008 BMW Z4 3.0i with the N52 3.0L engine. It combines one blue oiled filter, a molded intake tube, metal heat shield and black powder-coated cover. The original MAF transfers into the tube. Existing exact-retailer Coupe 3.0si coverage is retained with the engine and housing conflict qualified below.
Exact current aFe primary and the shared manual specify BMW Z4 3.0i 2006-2008, 3.0L N52. Existing Roadster 3.0i and Coupe 3.0si 2006-2008 rows are preserved with all original bounds. Exact-part retailer tables list the Coupe 3.0si, but the manufacturer headline/manual and indexed D-550-38 row name 3.0i; other 3.0si entries in that order refer to a different intake. The Coupe row therefore remains a source conflict requiring actual engine, airbox and MAF-housing confirmation, not a declaration of physical incompatibility. No Roadster 3.0si extension is made from isolated indexed retailer results, related intake numbers or the Coupe row. No later Z4 chassis or engine is added. Existing native vehicle membership remains unchanged.

One selected oiled filter is supplied; the dry filter illustrated in the shared bill is an alternative. The cover is included. Reuse the original MAF; no replacement sensor, factory plenum or extra filter is included. Procedure letters for the wing nut and cover screws conflict with the bill: use the actual wing nut with its sealing washer and four button-head cover screws. The sensor-screw pitch is printed ambiguously and is not silently converted into a verified specification.

One oiled Pro 5R filter, molded tube, metal shield, black cover, adaptor, angle coupling, two clamps, gaskets and the listed hardware. The dry filter is a separate alternative.
Which Z4 application does aFe identify?The current exact primary and shared manual specify 2006-2008 Z4 3.0i with the N52 3.0L engine. Existing Coupe 3.0si retailer coverage requires exact housing and engine confirmation.
Is the shield made from polymer?No. The detailed primary identifies an 18-gauge metal shield. The intake tube is molded, and a black powder-coated cover is included.
Is a new MAF supplied?No. Transfer the original MAF using the round gasket and supplied sensor screws, then reconnect its wiring.
How are the factory housing mounts removed?Twist the two plastic mounts half a turn to the left and pull straight up. Remove the bottom rubber mount as directed.
How is the wing-nut sealing washer installed?Install its rubber side down. Procedure letters differ from the bill, so identify the wing nut, sealing washer and cover screws by their actual components.
Do the chart and EO certify every listed configuration?No. The chart uses a different filter reference and shows 18 hp and 11 lb-ft maximum differences. Exact current D-550-38 scope and Coupe 3.0si exemption require further confirmation.
What battery, torque and recheck instructions apply?Follow negative-battery disconnection and restore the connection after work. The manual supplies no numeric torque and calls for retightening connections after approximately 100-200 miles.
Verify aFe 54-11942. Read all 12 pages and work with a cool engine. Follow the negative-battery instruction and disconnect MAF wiring. Loosen the original tube clamp and remove the intake assembly straight up from its two plastic mounts; remove the throttle-body coupling by pulling up rather than toward yourself. Remove the original MAF. Twist each plastic housing mount half a turn left, then pull up, and remove the bottom rubber mount. Route the new tube through the shield with its flange inside. Set the four long hex screws, slide in the flange gasket and fit the adaptor. Transfer MAF with the round gasket and two supplied sensor screws. Fit the angle coupling and clamps loosely. Position the assembly and secure the shield with supplied screws, nuts and washers, including the wing nut and sealing washer rubber side down. Reconnect MAF wiring, tighten clamps, fit the selected filter and secure its clamp. Install the cover with four button-head screws. Restore battery connection after work; the printed final steps do not separately repeat it. Apply the matching EO identification label only for its exempt application. Retighten connections after approximately 100-200 miles. No numeric torque is supplied.
Exact current primary, all 12 manual pages, all three page contacts, complete A1/A2/B-Q bill and figures A-E, and the actual linked dyno chart were reviewed. Detailed primary metal shield and included cover correct the old polymer-housing description. The linked chart was printed September 17, 2010 and compares September 16 fourth-gear runs acquired at 10:50 and 12:48. It records maximum 158 versus 140 hp and 146 versus 135 lb-ft, or 18 hp and 11 lb-ft peak differences, rather than certifying the advertised 15 lb-ft as a peak difference. Its intake-run filter is R24-60505, not the selected current replacement filter; vehicle details and complete matched environmental conditions are not established by the chart. No exact airflow report is linked. Current primary references D-550-38 and the indexed official row names Z4 3.0i 2006-2008. Full exact current order and Coupe 3.0si exemption remain held because prior source access encountered a challenge; no retry or broader related-part certification is used. Original positive Coupe retailer coverage is qualified and retained, not deleted for headline absence. Turn14 authenticated exact-product access remains unavailable. Prices, media and protected commercial data remain unchanged.
