aFe 51-76006 Momentum GT uses one three-layer oil-free synthetic Pro DRY S filter with a black sealed XLPE housing and matching resonated XLPE tube for the specified Toyota Land Cruiser/Lexus LX570 engine configuration. It transfers the original MAF and reuses the original vacuum and breather hoses.
The current exact intake pages name Lexus LX570 and Toyota Land Cruiser J200, 2008-2021, with the appropriate 5.7L or non-US 4.6L V8 configuration. Their shared manual is narrower: Land Cruiser 5.7L 2008-2020, Land Cruiser 4.6L 2012-2020 and LX570 5.7L 2012-2020. Earlier Lexus coverage and 2021 endpoints therefore rely on the current family specification rather than the older procedure cover. The existing table below retains its original year ranges and 2012 gap; it is not proof that every engine, regional trim or housing revision fits. Verify the actual engine, MAF, throttle body, original vacuum/breather hoses and mounting arrangement. A model/year match alone does not establish engine compatibility.
| Years | Make | Model | Named trim; actual engine and hood requirements apply |

Verify 51-76006 against the actual engine, sensor and vent connections, mounting locations and applicable emissions requirements before ordering.
| Brand | aFe POWER |
| Manufacturer Part Number | 51-76006 |
| Filter / quantity | 21-91092 / one three-layer oil-free synthetic Pro DRY S |
| Tube / housing | 05-76006B1 / 05-76006B2; black XLPE |
| Coupling / clamps | 05-01398 silicone hump / 03-50265 T-bolt and 03-50008 #052 |
| Hoses / original equipment | Both original vacuum/breather hoses, MAF and three mount assemblies reused |
| Recheck / torque | 100-200 miles / no numeric torque in exact manual |
| Bench-flow qualification | Both current exact pages advertise 243 CFM at 1.5 inches H2O and up to 30% more flow. Their Airflow Chart labels do not provide a linked bench chart in the reviewed pages, so a stock reference or media-specific measurement is not independently reconstructed. Do not compare this pressure directly with other kits tested at 7 inches H2O. |
| Dyno qualification | The linked chart tests the Pro 5R system on an LX570 5.7L. At 5,750 rpm the marked power is 294.78 hp baseline versus 315.68 hp intake, a 20.90-hp point gain. The separate marked torque values, 269.26 versus 288.35 lb-ft, are about 19.09 lb-ft apart at their marked high-rpm positions; they do not show the advertised maximum 25-lb-ft point. Run maxima are 295.30 versus 316.01 hp and 312.03 versus 325.25 lb-ft: 20.71 hp and 13.22 lb-ft peak-to-peak. The manufacturer advertises up to 21 hp/25 lb-ft; maximum point gains and peak-to-peak differences are distinct. BOTH runs list OE headers/exhaust/tuning, 10% preload, second gear, closed hood, blower fan, AWD and traction control off. SAE correction differs, 1.03 baseline versus 1.02 intake, with different temperature/humidity. This does not independently prove dry-filter, Land Cruiser or 4.6L performance. |
| Emissions | The current exact manufacturer page says the product is not currently CARB exempt and is unavailable for purchase in California or use on a vehicle registered with the California DMV. The intake manual also prohibits use on California-registered on-road and off-road vehicles. Do not treat the system as CARB approved. |

One selected Pro DRY S filter is supplied, not all the manual media alternatives. Reuse original MAF, three housing mounting screws/inserts/bushings and BOTH original vacuum/breather hoses. No replacement hoses are listed; do not borrow the 4.7L kit hose set. The Dynamic Air Scoop is sold separately. The shared illustrations show the family system, and the parts-list filter line identifies the selected medium.

Earlier Lexus coverage and 2021 endpoints therefore rely on the current family specification rather than the older procedure cover.

Which filter is included and how is it serviced?One 21-91092 Pro DRY S three-layer oil-free synthetic filter is supplied, 9 inches high with a 6-3/4 x 4-3/4-inch oval flange. Clean, fully dry and do not oil this dry filter.
Are original vacuum and breather hoses reused?Yes. The shared manual reconnects both original hoses. Its parts list does not include the two replacement hoses used by the separate 4.7L gasoline kit.
What sensor and mounting hardware transfer?Transfer the original MAF using two supplied M4 Torx screws, plus the three original housing screws, metal inserts and bushings. The inlet receives the supplied 26-inch trim seal.
Which coupling and clamp arrangement applies?Use silicone hump coupling 05-01398, one T-bolt clamp 03-50265 and one #052 clamp 03-50008. These are not the 4.7L reducer and two different T-bolt clamps. No numeric torque is provided.
Are the covers and optional scoop retained or included?Reinstall the engine cover and the Lexus side cover with all seven original clips. The Dynamic Air Scoop is a separate optional purchase; the plug is included, but its use does not certify fording depth.
What do the airflow and dyno figures actually establish?Both current exact pages advertise 243 CFM at 1.5 inches H2O and up to 30% more flow. Their Airflow Chart labels do not provide a linked bench chart in the reviewed pages, so a stock reference or media-specific measurement is not independently reconstructed.

The manufacturer advertises up to 21 hp/25 lb-ft; maximum point gains and peak-to-peak differences are distinct. BOTH runs list OE headers/exhaust/tuning, 10% preload, second gear, closed hood, blower fan, AWD and traction control off. SAE correction differs, 1.03 baseline versus 1.02 intake, with different temperature/humidity. This does not independently prove dry-filter, Land Cruiser or 4.6L performance.
What recheck and emissions restrictions apply?Recheck bolts, clamps and connectors after 100-200 miles. The current exact manufacturer page says the product is not currently CARB exempt and is unavailable for purchase in California or use on a vehicle registered with the California DMV. The intake manual also prohibits use on California-registered on-road and off-road vehicles. Do not treat the system as CARB approved.
Verify aFe 51-76006. With the engine cool, follow the manual battery-disconnection precaution. On Lexus, release and retain all seven side-cover clips and remove that cover. Disconnect MAF and unclip its wire loom; loosen the airbox connection, release four lid clips and remove the lid/filter. Remove the lower airbox with its three mounting screws, then remove the original inlet duct with two screws. Remove and retain the engine cover. Disconnect the original vacuum and breather hoses from the old tube, loosen the throttle-body clamp and remove the tube. Transfer the three original screws, metal inserts and bushings into the new housing, fit the 26-inch trim seal and secure the housing on its three original mounts. Lock the selected filter into the housing, leaving its connection loose during alignment. Transfer MAF using two supplied M4 screws, fit the brass hose nipple and install the silicone hump coupling at the throttle body using the #052 clamp and T-bolt arrangement. Insert the tube into the coupling then filter, align and tighten connections. Reconnect BOTH original vacuum/breather hoses and MAF. Select the auxiliary plug position. Reinstall the engine cover and, on Lexus, the side cover with all seven retained clips. Recheck bolts, clamps and connectors after 100-200 miles. No numeric torque is supplied in the exact manual.
