aFe 55-12541 Super Stock retains the original Toyota Tundra/eligible Sequoia airbox for the exact older 4.6L or 5.7L V8 application. It replaces the factory tube with a 3-1/2-inch wrinkle-black powder-coated mandrel-bent tube, uses one three-layer oil-free synthetic Pro DRY S panel filter, and includes silicone couplings and stainless clamps. A Silver Bullet throttle-body spacer is also included.
Toyota Tundra 2007-2013 with the actual 4.6L or 5.7L V8 and complete original airbox; use only model years with the actual matching engine. The exact current part-specific page covers 2007-2013. Its shared manual also covers later kits through 2021, but the EARLY dry filter is 31-10146, not the later filter. Exact-part retailer tables support Platinum 2010-2013 rather than only 2013. The signed D-550-16 Exhibit A additionally names this exact older kit for Sequoia 2008-2013, listed 4.6L/5.7L family with stock airbox retained; confirm the actual engine/housing for that vehicle. No new Sequoia named-trim rows or later-year scope are inferred.

| Brand | aFe POWER |
| Manufacturer Part Number | 55-12541 |
| Application | Tundra 2007-2013 / eligible Sequoia 2008-2013; exact actual V8 and stock airbox |
| Filter | One three-layer oil-free synthetic Pro DRY S OE-replacement panel |
| Tube | 3-1/2-inch wrinkle-black powder-coated mandrel-bent tube |
| Factory equipment retained | Original complete airbox and sensors |
| Couplings / intake clamps | Two / four |
| Bench flow | The current exact page states 197 CFM at 1.5 inches H2O and 13% flow increase. It does not link a separate flow chart; do not compare that result directly with charts measured at 7 inches H2O. Bench flow is not a filtration-efficiency or power guarantee. |
| Dyno qualification | The current exact manufacturer page advertises up to 18 hp and 30 lb-ft. No separate dyno chart is linked there to establish the engine, supporting modifications, measurement point or peak-to-peak comparison, so those advertised maxima are not independently confirmed here. Results are test-specific and are not guaranteed gains for every vehicle. |
| Emissions | The current page cites D-550-16 for some applications. The actual signed October 2014 Exhibit A explicitly lists this exact older kit for Tundra 2007-2013 and Sequoia 2008-2013, 4.6L/5.7L, retaining the stock airbox. That is an exact-application exemption, not approval of later kit years, every engine in every year, altered emissions equipment or changed tuning. Match the exact vehicle and install the required EO identification label on or near the intake for the covered inspection application. |

One selected filter is supplied; the alternatives in the shared manual are not additional filters. The original complete factory airbox and original sensors remain. The exact parts list and installation show the included throttle-body spacer and seals/hardware. Older retailer copy claims a Dynamic Air Scoop, but no separate scoop appears in this exact parts list or procedure; a supplied scoop is not confirmed. The selected filter is dry synthetic, despite older mixed Pro 5R copy. The current overview heading also says Pro 5R while its detailed text and selected service filter are oil-free Pro DRY S; dry media governs. Use the EARLY filter 31-10146.

Does the selected filter need oil?No. Service the oil-free synthetic filter with an appropriate dry-filter cleaner, rinse as directed and allow it to dry fully; do not oil it.
Is the factory airbox replaced?No. The original complete airbox remains; replace the panel filter and fit the supplied tube and couplings. Original sensors remain in service.
Which sensor and hose connections matter?Temporarily disconnect and then reconnect the original MAF harness. Reconnect vacuum and crankcase hoses, replacing the 1/2-inch crankcase hose with the supplied one and retaining its factory clamps.
Is a scoop or spacer supplied?One selected filter is supplied; the alternatives in the shared manual are not additional filters. The original complete factory airbox and original sensors remain.

Are the advertised gains peak-to-peak results?The current exact manufacturer page advertises up to 18 hp and 30 lb-ft. No separate dyno chart is linked there to establish the engine, supporting modifications, measurement point or peak-to-peak comparison, so those advertised maxima are not independently confirmed here. Results are test-specific and are not guaranteed gains for every vehicle.
What exact emissions and recheck requirements apply?The current page cites D-550-16 for some applications. The actual signed October 2014 Exhibit A explicitly lists this exact older kit for Tundra 2007-2013 and Sequoia 2008-2013, 4.6L/5.7L, retaining the stock airbox. That is an exact-application exemption, not approval of later kit years, every engine in every year, altered emissions equipment or changed tuning. Match the exact vehicle and install the required EO identification label on or near the intake for the covered inspection application. Recheck connections after 100-200 miles; the exact intake manual provides no numeric torque.
Verify aFe 55-12541. Lift off the engine cover, loosen the original tube clamps, disconnect crankcase/vacuum hoses and temporarily disconnect the MAF harness. Remove the tube and replace the panel filter inside the retained original airbox. Remove the four throttle-body bolts and original O-ring. Install the specified replacement O-ring, spacer and gasket in the manual sequence and use the supplied replacement hardware without overtightening. Fit the reducer coupling at the factory housing, add the brass fitting to the tube and loosely assemble the other coupling and four clamps. Replace the factory 1/2-inch crankcase hose with the supplied hose while reusing the factory hose clamps. Insert the tube housing-side first, connect it to the throttle body, reconnect crankcase/vacuum lines, align and tighten. Reinstall the engine cover and reconnect the original MAF harness. The shared manual fitting-thread text is malformed; match the supplied fitting rather than treating that typography as a valid thread specification. No numeric torque is supplied in this exact intake manual. Recheck all bolts/screws, clamps and connectors after 100-200 miles as directed.
