aFe 54-74207 is the Momentum GT intake for specified Cadillac CTS-V supercharged 6.2L LSA applications. One Pro 5R filter fits the XLPE housing. The XLPE tube connects through a silicone coupling, and a supplied grille-fed scoop routes inlet air to the housing. Body-specific year limits, the original mounting parts and the optional-cover distinction apply.
Exact current manuals and the D-page fitment note distinguish CTS-V LSA sedan 2009–2014, wagon 2011–2014 and coupe 2011–2015. The broad 2009–2015 CTS/V database row is retained as an umbrella for those conditional body-specific applications, not blanket approval of every body in every year. It does not approve the later-generation 2015 CTS sedan, non-V engines or later LT4 CTS-V. No existing year bounds or named groups are changed; confirm the actual LSA engine, body generation and sensor/vent layout.

The shared multi-configuration manual labels carbon cover 05-74207C4 for a separate cover configuration and makes its installation conditional on an additional purchase. The D page explicitly calls its cover accessory sold separately. The R page says both included and sold separately, so a carbon cover is not guaranteed with this standard selected SKU. Accessory names also vary between -C and -CV in current page text; verify the exact accessory separately. This does not make the XLPE tube or housing carbon fiber. The exact manual identifies the 91107 filter and current service listings give a seven-inch height, conflicting with the generic five-inch overview; no five-inch substitution is assumed. Transfer two small grommets plus the separate grommet with steel insert from the original housing. Reuse the original housing screw and two plastic scoop rivets. The three engraved screws fit the housing even without an optional cover. No new MAF, extension, coolant hose, auxiliary-inlet plug or mounting grommets are listed. Service supplies are separate.
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 24-91107 Pro 5R filter; alternate media rows do not mean two filters in the selected kit.
Does the dry filter need oil?No. D uses three-layer oil-free synthetic media; R uses five-layer pre-oiled cotton gauze.
Does the 2009–2015 database row cover every CTS body?No. The exact LSA scope is sedan 2009–2014, wagon 2011–2014 and coupe 2011–2015; actual body generation and engine matter.
Is a carbon fiber cover guaranteed?No. It is optional for these standard kits. Conflicting included/sold-separately R-page prose and accessory suffixes require exact package confirmation.
Does installation require front-end access?Yes. Open the top of the grille/bumper, move the fabric diverter aside or cut it as instructed, fit the scoop, and restore all removed trim and fasteners.
Which grommets and fasteners are reused?Transfer two small grommets and the separate grommet with steel insert. Reuse the housing screw and two plastic rivets securing the scoop.
Should the NPT fitting hex touch the tube?A small gap is normal. Do not overtighten the fitting to remove it.
What torque and inspection interval apply?No numeric torque is specified. Check bolts, clamps and connectors after 200 miles and restore both engine covers.
Verify aFe 54-74207. Work on a cool engine. Remove the main engine cover and side trim. Loosen the throttle-body and housing clamps, disconnect MAF harness and vent fitting, and remove the tube. Remove and save the original 10mm housing screw, then lift out the housing. Release the quarter-turn rivets and top bumper trim, then the screws and push clips needed to open the top of the grille/bumper. Gently pull that assembly enough to reach behind it. Remove the fabric air-diverter rivets and either fold the diverter aside or cut it away as the exact manual permits, creating the scoop opening. Slide and orient the supplied scoop through this opening. Transfer the two small original grommets and the separate original grommet with steel insert to the new housing. Position the housing and connect the scoop while supporting it from the bumper opening; secure the scoop with two original plastic rivets and the housing with its saved screw. Seat the selected filter and leave its clamp loose. Fit the coupling at the throttle body. Transfer MAF with the two supplied M4 x 0.7 x 10mm screws. Install the NPT aluminum vent fitting without overtightening; a small gap below its hex is normal. Fit the tube into the filter first, then the coupling. If necessary open the T-bolt clamps by removing and reinstalling their nuts; align the assembly and tighten all clamps. Reconnect MAF harness and vent hose. Verify scoop placement, restore the bumper/grille fasteners and top trim, and reinstall both engine covers. Fit the optional cover only if separately supplied; otherwise install the engraved screws on the housing. Recheck bolts, clamps and connectors after 200 miles. No numeric torque or battery-disconnection step is specified.
Both linked flow images are byte-identical and display separate media bars: Pro 5R 580 CFM, Pro DRY S 550 CFM and stock 390 CFM at 7 inches H2O. These correspond to approximately 48.7 percent and 41.0 percent above stock. The R-page headline says 45 percent, so that headline and the linked 580-CFM chart are not silently treated as an identical calculation. The R-linked 2009 CTS-V dyno marks power 497.26 versus 466.63 hp near 5,920 rpm, a 30.63 hp difference, and torque 441.14 versus 413.98 lb-ft, a 27.16 lb-ft difference. Independent maxima 510.88 versus 477.57 hp differ by 33.31 hp and 484.74 versus 470.55 lb-ft differ by 14.19 lb-ft. The January 4 and March 8, 2016 runs state fourth gear and 285/30/21 wheels, with OE manifolds/headers and exhaust; the intake run is labeled after miles. Baseline conditions are 68.89°F/29.93 in-Hg/31% humidity with SAE 1.01; intake conditions are 63.35°F/29.09 in-Hg/39% with SAE 1.00. These different-date point comparisons differ from independent peak differences and do not guarantee every vehicle’s gains. Current pages state this intake is not CARB exempt and unavailable for California purchase or California-registered vehicles. The older manual’s California race-only wording does not establish current exemption or dealer sale permission.
