aFe 50-73004 is the Momentum HD intake with one Pro 10R filter for specified 2008–2010 Ford 6.4L Power Stroke diesel trucks. The exact illustrated manual names F-250, F-350, F-450 and F-550. Its production-date-dependent crankcase connection must match the actual vehicle.
The exact 12-page manual names 2008–2010 Ford F-250/F-350/F-450/F-550 with the actual 6.4L turbo diesel. Original F-250 and F-350 year bounds are retained; missing F-450 and F-550 model groups use those same exact-manual years. All rows require the matching diesel engine, inlet, sensor and mounting layout; a model name alone does not approve its gas engines. No later generation, invented engine or drivetrain submodel, or unverified named-trim extension is added. Check the original crankcase-breather elbow, production date and actual hose hardware before choosing the illustrated branch.

The exact selected manual lists one Pro 10R filter. Reuse the MAF, original filter minder and its factory grommet, original housing mounts and the original breather elbow where the stated production branch requires it. The supplied new rubber grommet serves the crankcase connection. Do not add the 6.7L fixing clamp, washer, support screw, extension harness or seal trim to this kit. The illustrated text refers to large clamps in the plural, but the exact BOM lists one large T-bolt; confirm supplied hardware rather than inventing another clamp. Maintenance kits, pre-filter and unrelated tuner packages 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 20-91061 Pro 10R filter. Alternate media in comparison charts is not another included filter.
Does the manual name F-450 and F-550?Yes, for 2008–2010 with the actual 6.4L diesel and matching hardware. This does not approve gas engines in the same model.
Are new sensors included?No. Transfer the original MAF and filter minder, preserving the original connections.
Is a MAF extension supplied?No extension appears in this exact BOM. Follow the original harness routing and clearance shown in the manual.
What sensor screw length is specified?This exact manual identifies M4 screws but gives no length; do not borrow dimensions from a later kit.
What original hardware needs attention?Confirm the production-dependent crankcase elbow, original minder grommet and housing mounts.
Are dyno headline gains guaranteed?No. Marked point gains differ from independent peak gains, and the manufacturer test vehicle and conditions are specific.
What torque and recheck interval apply?No numeric torque is given. Recheck all connections and clamps after 100–200 miles as this manual states.
Verify aFe 50-73004. Read the complete exact manual and disconnect both batteries before removing the MAF and filter-minder harnesses. Release the original crankcase-breather clamp by prying or cutting the clamp as instructed; do not blindly cut the hose. Remove the original tube, auxiliary air connection and housing. Wipe excess oil from the filter flange with acetone as the manual directs, not from the filter media; preform and fit the supplied large clamp. Transfer the MAF with the two supplied M4 screws, original filter minder and its original grommet, and install the supplied crankcase grommet. Place the hump coupling on the tube without tightening clamps initially. Leave the housing partly unseated. Approach the turbo connection with the tube at about 45 degrees, then rotate it into the filter while simultaneously pressing the housing into the factory grommets. Restore the auxiliary air line and fit the two worm clamps over the turbo coupling before tightening the connections. The manual specifies reusing the original 90-degree breather elbow on trucks built before May 6, 2007, and fitting the supplied plastic elbow and mini-clamp on the branch after May 7, 2007. Its wording does not resolve the two boundary dates; confirm actual production hardware rather than inventing inclusive date rules. Reconnect both sensor harnesses and both batteries. Choose the optional auxiliary plug position as described. No numeric torque is supplied; recheck all connections and clamps after 100–200 miles.
The current primary advertises 24-percent flow and up to 20 hp/35 lb-ft. The actual flow chart shows Pro 10R 410, alternate Pro DRY S 380 and stock 330 CFM at 7 inches H2O; the selected oiled comparison is about 24.2 percent. The linked dyno’s marked points differ by 22.12 hp (281.62 versus 259.50) and 38.05 lb-ft (484.58 versus 446.53), while independent peaks differ by 17.52 hp (282.71 versus 265.19) and 37.42 lb-ft (484.66 versus 447.24). These do not exactly reproduce the page headline. Both runs used an 8-inch lift, 35-inch tires, TCS off, 40-percent brake and an aFe 4-inch cat-back. Baseline April 11, 2013 conditions are 75.66°F/28.98 in-Hg/20% humidity/SAE 1.02 versus intake April 25 conditions 77.61°F/29.08/33%/SAE 1.02. The intake run label includes “100% clocked MAF after 200 miles”; that test label is not an installation instruction to alter sensor orientation outside the exact manual. Results are configuration- and condition-specific, not guaranteed. Official indexed D-550-24 exhibit text names the exact selected kit for 2008–2010 F-250/F-350 and separately F-450/F-550 6.4L. Full exhibit image review remains unavailable; verify actual current legality and required identification rather than treating model fitment as blanket exemption.
