aFe 51-76314 is the Momentum GT Pro DRY S intake for qualified non-US BMW N13 1.6L turbo applications. It supplies one 21-91056 element with three oil-free synthetic layers, a molded polyethylene housing and tube, and a silicone turbo coupling with aluminum fittings for the two original hoses.
This is a non-US N13 1.6L turbo application. The current product page identifies 116i/118i F20/F21 2011-2015. The exact manual instead lists 114i F20/F21 2012-2015, 116i F20/F21 2011-2015, 120i F20/F21 2015-2016, 316i F30/F31/F36 2012-2015 and 320ed F30 2012-2015. The 118i page/manual difference and the manual chassis combinations require vehicle-specific confirmation. Existing structured fitment contains no named vehicle selections and is preserved pending exact supported regional configuration data. None of these engine labels is converted into a US trim or universal fitment.

The oiled filter in the shared bill belongs to the separate media option. The illustrated filter-to-tube clamp is distinct from the itemized housing and coupling clamps. Retain the original MAF sensor, two vehicle hoses, mounting grommet and hood-latch cable. No new sensor, module or separately numbered auxiliary plug is itemized; the overview plug claim requires actual-box confirmation. The current manual and photos do not establish a clear inspection window. Do not assume a window or a different filter flange from another Momentum intake.
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 21-91056 Pro DRY S element with three oil-free synthetic layers and 9-inch height. The oiled row in the shared bill is a separate media option.
Is this listed for a US BMW model?The manufacturer expressly identifies the application as non-US. Confirm the actual N13 engine, regional chassis and connections.
Why does the model list require confirmation?The product page names 116i/118i while the exact manual lists 114i, 116i, 120i, 316i and 320ed configurations. Those differences do not establish additional US trim mappings.
Are both original hoses retained?Yes. Reconnect the two hoses removed from the original turbo tube to the aluminum fittings on the supplied silicone coupling.
Is a new MAF sensor supplied?No. Transfer the original sensor using the supplied M4 screws; no screw length is specified.
Must the hood-latch cable be restored?Yes. Refit it into the dedicated slot on the new housing after reconnecting the MAF harness.
Is a selected dry comparison chart available?The current page states 150 CFM at 7 inches H2O and performance data coming soon, but links no airflow comparison or dyno. Do not treat a different-media chart as dry certification.
What tightening and follow-up checks apply?Align the assembly before securing the clamps, then recheck bolts, clamps and connectors after 100-200 miles. The exact manual gives no numeric torque.
Verify aFe 51-76314. Read all sixteen PDF pages and figures A-I; printed page numbers repeat in this document. Work on a cool engine and disconnect the negative battery terminal as directed. Disconnect the MAF harness, unclip the hood-latch cable and loosen the original tube clamps. Remove the housing from its mounting grommet, then remove the turbo tube after disconnecting its two hoses. Transfer the original housing grommet, install the selected filter with clamps loose, and seat the housing in the vehicle mounts. Transfer the original MAF sensor with the supplied M4 screws. Fit the clamps to the silicone coupling, place the coupling over the turbo, and reconnect both hoses to its aluminum fittings. Leave those joints loose until the tube is inserted into the coupling first and then the filter. Align the filter, tube and coupling, secure every clamp, reconnect the MAF harness and restore the hood-latch cable into the housing slot. Recheck bolts, clamps and connectors after 100-200 miles. No numeric tightening torque is provided.
The exact current dry page, all sixteen PDF pages, bill, assembly diagram and figures A-I were read and viewed. Printed manual page numbers repeat; the file is byte-identical to the current oiled manual and explicitly identifies both media choices. The dry page states 150 CFM at 7 inches H2O and performance data coming soon; it links no airflow comparison chart or dyno. The separate oiled chart at a different pressure is not a selected dry test certification. The replacement-filter round flange differs from generic oval overview wording; confirm the actual filter and housing revision. The overview says an auxiliary urethane plug is included, but no separately numbered plug is in the exact bill; verify actual contents. Neither the current bill nor its images establishes a clear inspection window. Manufacturer non-US language is not regulatory approval for an imported vehicle, and the exact manual prohibits use on California-DMV-registered vehicles. Existing empty vehicle selections and application restrictions remain pending exact regional configuration proof. The primary 118i listing and manual model/chassis combinations require individual confirmation.

An open-element or short-ram layout places the filter differently and can change the audible induction character. A longer routed intake, a short-ram system and a factory-airbox tube replacement involve different installation scopes.Compare the actual filter position, heat-shield/enclosure design, retained ducts and access for maintenance. A cold-air label alone does not establish a lower inlet temperature in every driving condition or a fixed horsepower gain.
