aFe 51-76205-1 Momentum GT is the Pro DRY S intake for Grand Cherokee WK2 2011β2021 and Dodge Durango with the naturally aspirated 5.7L HEMI. The Jeep SRT hood is expressly excluded; the manufacturer separately permits the Dodge Durango SRT hood. Oil-free, three-layer synthetic Pro DRY S; no filter oil required.
The current manufacturer page names WK2 Grand Cherokee 2011β2021 and Durango 2011β2026, all with the actual naturally aspirated 5.7L HEMI; the current manual's Durango coverage ends in 2023. Named additions here stop at 2023 pending later exact configuration review. The Jeep SRT hood remains excluded even when a retailer lists a matching trim; this exclusion is not applied to the Dodge SRT hood. Confirm actual engine, hood and airbox/mounting interfaces. This does not approve V6, SRT 6.4L, supercharged 6.2L, Grand Cherokee L/WL or later WK2 substitutes.

| Brand | aFe POWER |
| Manufacturer Part Number | 51-76205-1 |
| Application | WK2 Grand Cherokee 2011β2021 / Durango 5.7L; current PDP through 2026 versus manual through 2023, later named coverage qualified. |
| Filter | Oil-free, three-layer synthetic Pro DRY S; no filter oil required. |
| Element dimensions | One nominal 8-inch radial-flow element; no dimensions borrowed from the 6.4L filter. |
| Housing and tube | One-piece sealed housing with sight window and auxiliary scoop; roto-molded tube. Exact housing/tube resin not separately established here. |
| Coupling | Current manual: silicone bellows 05-01743, 3-1/2-inch ID x 3 inches long. Product prose also calls it a hump coupling; match actual revision. |
| Published performance | Product page reports 34% flow improvement and 500 CFM at 7 inches H2O, while the paired oiled page gives 42% with the same 500-CFM text. The baseline/test consistency is unresolved; no recalculated exact gain is certified. |
| Dyno test qualification | Both linked charts identify 54-72242 Momentum AIS, a different part/revision from these exact listings. Factory exhaust/headers and third-gear test notes are visible; point gains are not the separate peak-power changes. No exact current-kit power guarantee is inferred. |
| Emissions qualification | D-550-58's available official application table names both exact kits for Grand Cherokee 2011β2021 and Durango 2011β2023, 5.7L naturally aspirated. Later Durango exemption is not established. |
| Quantity | Manufacturer service part | Component |
|---|---|---|
| 1 | 21-91062 | Pro DRY S filter; shared-manual alternative is not another included element |
| 1 each | 05-76205B3 / 05-76214B2 | Intake tube / housing |
| 1 | 05-01743 | Silicone bellows, 3-1/2-inch ID x 3 inches long |
| 1 | 03-50290 | T-bolt clamp listed in current BOM |
| 2 | 03-50009 | #056 clamps, 3-1/16 to 4 inches |
| 1 each | 03-50167 / 05-01454 | New temperature-sensor grommet / fitting |
The current BOM lists one T-bolt and two #056 clamps, while the steps also describe separate housing/filter and tube/filter clamp positions. Match the boxed clamp set and current revision rather than inventing an extra included T-bolt. The original temperature sensor, crankcase-vent hose and mounting grommets are reused. Follow the correct Pro DRY S cleaning procedure and do not oil the filter.
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
The actual 5.7L HEMI in the stated WK2 Grand Cherokee or Durango. The manufacturer excludes Jeep Grand Cherokee SRT hoods but separately permits the Dodge Durango SRT hood; a shared trim label cannot override that distinction.
Which filter is included?Oil-free, three-layer synthetic Pro DRY S; no filter oil required. The exact version uses one 21-91062 filter. Follow the correct Pro DRY S cleaning procedure and do not oil the filter.
Is the current coupling a silicone bellows?Yes. The current shared manual lists 05-01743, a 3-1/2-inch-ID by 3-inch silicone bellows. Older product prose calls it a hump coupling, so identify the actual revision.
Are every clamp position and quantity identical in the manual?No. The current BOM lists one T-bolt plus two #056 clamps; the procedure also describes separate housing/filter and tube/filter clamp positions. Confirm the boxed hardware instead of assuming an extra new T-bolt.
Which sensor and hose are reused?The original intake-air-temperature sensor is twist-locked into a new grommet/fitting in the original orientation. The factory crankcase-vent hose and mounting grommets are retained; no new MAF sensor is listed.
Are the linked dyno figures an exact current-kit test?No. Both linked charts identify 54-72242 Momentum AIS. Published maximum point gains differ from increases between peak values, and an identical current -1 kit/media test is not independently established.
Does later Durango fitment equal later emissions exemption?No. Current product pages extend the 5.7L family to 2026, but the full manual and available D-550-58 application table stop at Durango 2023. Confirm exact later hardware, named trim and emissions coverage separately.
When are connections rechecked?The exact 5.7L manual says to check clamps and connectors after 200 miles. Restore the factory scoop trim seal and clips, sensor and vent connections, and engine cover. No numeric torque is supplied.
Verify aFe 51-76205-1. Work on a cool engine and retain original parts. Lift off the engine cover, remove the tube support screw, disconnect the temperature-sensor harness and crankcase-vent hose, loosen the throttle-body clamp and release a rear vent-hose clip if present. Lift the factory scoop trim seal and two or three clips each side to remove the intake without damaging them. Transfer factory mounting grommets to the new housing. Twist the original temperature sensor out carefully, preserving its orientation; fit the new grommet/adaptor and lock the original sensor in the same direction. Assemble the filter/housing and revision-correct clamps, seat the housing in its grommets, and assemble the silicone bellows at the throttle body. Insert and align the new tube, tighten its matched clamps, reconnect the sensor harness and original vent hose, and reinstall the engine cover and factory trim seal in their original locations. Verify every connection and recheck clamps/connectors after 200 miles. No numeric torque is specified.
Confirm the actual naturally aspirated 5.7L and hood. The manufacturer's Jeep SRT-hood exclusion remains in force even for retailer-positive Limited X applications; no unconditional Limited X addition is made here. Later Durango 2024β2026 manufacturer coverage, named trims and emissions require separate confirmation beyond this manual/EO scope. Current product pages cite D-550-58. Verify the complete applicable order, vehicle and kit revision, and use the required EO identification label as instructed; a broad 50-state claim for every listed year is not established. Dyno/flow figures are manufacturer test claims with the revision limits above, not guaranteed power, mileage, fault-code or warranty outcomes.
