aFe 50-70036R is a Momentum GT intake using one pre-oiled five-layer cotton gauze Pro 5R filter, an XLPE intake tube and an XLPE housing with a clear round inspection window. The exact manual covers specified Audi A3/A3 Quattro, Golf, Golf R, GTI and Jetta GLI turbo engines with individual year limits. It includes the smog-pump fitting or block-off cap route for the actual installed equipment. Current primary explicitly excludes Audi A3 with the 40 TFSI engine; confirm that restriction before ordering.
Apply the current primary A3 40 TFSI exclusion to every A3 row. Own manual: A3 1.8L turbo 2015-2018, A3 2.0L turbo 2017-2020, A3 Quattro 2.0L turbo 2015-2020, Golf 1.8L turbo 2015-2018, Golf R 2.0L turbo 2015-2019, GTI 2.0L turbo 2015-2021 and Jetta GLI 2.0L turbo 2019-2023. The manual broad 1.8L endpoints and exact retailer engine tables differ; verify actual engine, housing and ports rather than using year alone. Existing A3 TDI Premium/Premium Plus/Prestige 2015-2016 rows have positive exact retailer entries but conflict with the manual gasoline turbo scope; they remain unchanged as source holds, not physically-incompatible declarations or diesel certification. S3 named entries are exact retailer-supported 2.0L applications, with Canadian Progressiv/Technik identity qualified; the manual cover does not separately name S3. Restore A3 Quattro Premium through 2020, missing Premium Plus, GTI Rabbit Edition 2019 and S3 Technik 2020. Add Golf SE 2015-2016 while retaining its separate 2018 row; 2017 SE has a positive engine table but remains a gap/source hold against other exact tables. Add Jetta GLI Autobahn 2019-2023, GLI S 2019-2021 and GLI 35th Anniversary Edition 2019. Later 2024-2026 GLI positives remain held against the own 2023 manual endpoint; non-GLI Jetta and unrelated engine/housing rows are not inferred.

The three bottom mounting grommets are supplied, rather than transfers from another kit. The smog-port grommet is a fourth, different grommet. Install the cap or aluminum fitting to suit the actual smog-pump equipment; both are itemized alternatives for that port. The filter flange clamp is used in preassembly separately from #044 and #048 tube clamps. No new sensor, MAF adaptor, battery cable, intake scoop or hose assembly is itemized. The brass breather nipple is called 3/16 inch in the procedure; no reducer dimensions or numeric clamp torque are printed.
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, tube, housing, reducer, #044/#048 clamps, three bottom grommets, separate port grommet, smog-pump fitting, alternative cap, brass breather nipple and auxiliary inlet plug.
Does it fit an Audi A3 40 TFSI?The current exact manufacturer explicitly says it does not fit A3 models with the 40 TFSI engine. Apply that exclusion even if a broader year/trim table lists the car.
Are the positive TDI retailer rows verified diesel approval?No. Those existing rows conflict with the gasoline turbo manual scope and remain qualified source holds pending exact engine/housing reconciliation. They are not deleted from headline absence alone.
What years does the own manual name for Jetta GLI?2019-2023 with the 2.0L turbo. Exact named evidence supports GLI Autobahn 2019-2023, GLI S 2019-2021 and GLI 35th Anniversary Edition 2019; later positive rows remain held.
What if the vehicle has a smog pump?Use the separate port grommet and aluminum fitting, then reconnect the original hose. Without the pump, use the supplied plastic cap instead.
How does the housing engage?Preassemble tube and filter, then press and rotate them into the housing until all six tabs seat. Install all three supplied bottom grommets before seating the housing on the original mounts.
Is the advertised 28 lb-ft a peak-to-peak increase?No. The marked 4,500 rpm point differs by 28.16 lb-ft, while separate listed maxima differ by 6.18 lb-ft. Dates, weather and SAE factors also differ between the runs.
Is there a stated torque or battery step?Neither is given. Install reducer with #044 at the turbo inlet, rotate the tube into it and secure #048 after alignment. Check bolts, clamps and connectors after 100-200 miles.
Verify aFe 50-70036R. Read all twelve pages and figures A-G with a cool engine. Disconnect the smog-pump connector if applicable and crankcase breather, loosen the turbo connection and carefully lift out the original intake assembly; alternatively remove its upper airbox section with the T25 driver. Install all three supplied bottom grommets. Install the separate port grommet with the plastic block-off cap if there is no smog pump, or with the metal fitting if equipped. Install the brass breather nipple in the tube. Insert tube into filter and tighten its clamp, then press and rotate both into the housing until all six tabs are felt or heard seating. Install reducer and smaller #044 clamp on the turbo inlet and tighten that clamp; place the loose #048 clamp on the reducer. Place the assembly in the engine bay and reconnect the rubber breather hose; a small amount of lubricant on the brass nipple may help as noted in the manual. Press the housing onto all three original mounting locations, then rotate the tube down into the turbo-inlet coupling. Align it clear of surrounding components and tighten #048. Reconnect the smog-pump hose to the aluminum fitting only if equipped, then check all connections. The auxiliary housing inlet can be plugged as described by the manufacturer; no measured plug-position comparison is supplied. This manual gives no sensor-transfer or battery-disconnection step and no numeric torque. Check bolts, clamps and connectors after 100-200 miles.
The exact current manufacturer page and all twelve pages of the own illustrated manual, full bill and figures A-G were read and viewed. Primary explicitly excludes A3 40 TFSI. The manual gives engine/year coverage beyond the Golf R headline, including Jetta GLI 2019-2023; headline absence alone is not a deletion basis. Positive diesel and broader retailer rows are recorded source conflicts rather than invented incompatibility. Exact named tables support the restored groups, while Golf SE 2017, later GLI bounds and wider non-GLI entries remain held. The manual expressly supplies a smog-pump fitting/cap choice; an isolated search snippet for another product on a catalog page is not used to declare this entire kit secondary-air-incompatible. Actual flow chart is 370 versus 320 CFM at 7 inches H2O: calculated 15.625%, rounded advertised 16%. Actual selected dyno marked point at 4,500 rpm is 24.13 HP and 28.16 lb-ft; separate maxima differ by 23.97 HP and 6.18 lb-ft. The advertised 24 HP/28 lb-ft does not mean 28 lb-ft peak-to-peak. The 2018 Golf R intake run was September 4, 2018 at 2:37 PM, before the September 27 baseline at 2:33:22 PM. Both specify fourth-gear pulls and stock exhaust/full-stock baseline; intake SAE factor 1.04 versus baseline 1.05, 87.750 versus 95.740 F, 29.090 versus 29.100 in-Hg, humidity 42.97% versus 29.96%. Conditions differ; no hood or fan settings are printed. Gains are test-specific. Manufacturer states non-CARB status and California purchase/registered-vehicle restriction.
