aFe 51-82952-C is the Magnum FORCE Stage-2 Si intake for the 2008-2013 BMW M3 with the 4.0L S65 V8. This selected configuration includes one oil-free Pro DRY S filter and the carbon-fiber-look ABS trim cover. The housing and tube are molded plastic; the decorative finish does not make this a structural carbon-fiber or aluminum intake.
Current exact primary supports BMW M3 E9X 2008-2013 with the naturally aspirated 4.0L S65 V8; exact retailers list the original Base application. The current instruction cover prints E90/E91/E92 while selected commercial application text identifies E90/E92/E93. That chassis-label discrepancy does not establish a production E91 M3 or permit other 3-Series engines. Original Base bounds and vehicle selections remain unchanged; larger-displacement or special-edition compatibility is not inferred. Indexed official D-550-38 Exhibit A names this exact part family for M3 2008-2013 4.0L naturally aspirated gasoline, but full current order conditions remain held after the earlier official access challenge.

The shared oiled filter and black cover are alternate configurations, not extra supplied parts. Reuse the original smog-pump hose, original duct connection and two original airbox bolts. No new MAF, IAT sensor or sensor screws are listed; do not substitute a different M3 intake transfer procedure. The current bill contains no separate silicone hose despite generic primary component prose. Exhausts, pulley, dynamic scoops, cleaners and prefilters are separate accessories. The existing Carbon Fiber tag describes the look option and is not proof of structural carbon-fiber construction.
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 oil-free dry filter, molded tube and sealed housing, carbon-fiber-look ABS cover, separate duct, silicone hump coupler, smog fitting/grommet, two main clamps and five cover screws/washers.
Is the cover real structural carbon fiber?The manufacturer describes vacuum-formed ABS with a carbon-fiber-look finish. The housing and tube are molded plastic.
Which filter and media are selected?The selected filter is 21-91093 with three layers of oil-free synthetic media. The shared oiled filter is an alternative; do not oil the dry filter.
How does the new duct connect?Insert its square end into the original duct first, then seat the round end in the new housing. Retain the original duct connection.
Are a new MAF or IAT supplied?Neither is listed in this bill. The specified transfer is the original smog-pump hose to the new fitting, plus reuse of the original housing bolts.
Does the linked dyno certify this dry kit?No. It names an earlier oiled kit without cover and compares runs on different dates with different SAE factors. It is not a selected dry-filter gain certification.
Is 50% airflow the current dry comparison?No. The linked chart shows 685 versus 530 CFM at seven inches H2O, approximately 29.2%. The 785 figure is the alternate oiled media.
What battery, torque and recheck steps apply?Disconnect the negative terminal before work and verify its restoration before use. The manual gives no numeric torque; check bolts, clamps and connectors after 100-200 miles.
Verify aFe 51-82952-C. Read the complete current twelve-page manual and figures A-G. Work on a cool engine and disconnect the negative battery terminal. Loosen the intake-manifold clamp, disconnect the original smog-pump hose, remove and retain the two original airbox bolts, and remove the original tube, airbox and scoop. Install the supplied grommet and smog fitting in the new tube. Fit the tube into the selected dry filter and secure its clamp, then slide the silicone hump coupler far enough over the tube to ease installation. Insert the filter/tube assembly into the new housing and guide the assembly into the engine bay. The manual permits initially positioning the tube/coupler over the manifold without clamps to ease alignment; complete the final clamped assembly before operation. Insert the new duct square end into the original duct first, then place its round end into the new housing. Align the tube and airbox without strain, secure both manifold-side clamps, reconnect the smog-pump hose and restore both original mounting bolts. Install the selected cover with all five supplied screws and washers. Verify the negative battery terminal is restored before operation; the numbered finish step does not separately repeat its reconnection. Apply the enclosed EO identification label only for the applicable approved configuration and confirm the actual order requirements. Check bolts, clamps and connectors after 100-200 miles. No numeric torque is specified.
The exact current primary was located through the observed manufacturer variant link whose URL omits a hyphen; the normal catalog search alone had not found it. The complete currently linked twelve-page manual, full bill, assembly diagram and all figures A-G were read and viewed, together with the actual flow and dyno images. The older sixteen-page publicly indexed manual is not represented as this current revision. The current flow chart gives dry 685, oiled 785 and stock 530 CFM at seven inches H2O; dry improvement is about 29%, not the older retailer 798 CFM/50% claim. The linked dyno instead identifies an earlier oiled 54-82952-B without its cover on a 2008 M3. Its red/blue maximum figures differ by 7.99 hp and 1.19 lb-ft, at different torque peak RPM. Runs were on August 28 versus August 27, 2018 with SAE factors 1.02 versus 1.04. Both note original headers/exhaust/ECU, 265/35R18 tires, large fan, open hood, Power mode and fourth gear. Those results and advertised 6 hp/6 lb-ft are not certified selected dry-kit gains. Exact order indexing supports the listed M3 family, but full D-550-38 conditions remain unverified after the earlier robot challenge. No retesting, tuning requirement or guarantee is inferred.
