aFe 54-10322 is the current Rapid Induction Pro 5R intake for the Audi A4 B6 1.8L turbo, formerly described as Magnum FORCE Stage-2 XP. It includes one main oiled filter, molded turbo inlet tube, metal shield, aluminum cover and a separate small air-pump breather filter. Transfer the factory MAF and reconnect every specified breather, switch valve and fresh-air duct.
Current exact primary and manual identify A4 B6 2002-2005 1.8L turbo. Exact GoTurbo and MVP tables positively identify the existing five groups, including A4 Cabriolet 2003-2006 and A4 Quattro Cabriolet 2004; all original bounds are retained. The later Cabriolet year is an exact retailer-supported physical fitment qualification, not proof that the 2006 vehicle is covered by the reviewed emissions order. Confirm actual 1.8T engine, MAF pad, air-pump and all five vent locations. No 2.0T or different-platform mapping is inferred. Full D-550-30 Exhibit A names the selected kit for Audi A4 2002-2005 1.8L turbo; verify the exact vehicle and order conditions.

The shared dry filter reference is an alternative. Only one full-size main filter and one small air-pump breather filter are included. The original MAF, switch valve, saved factory elbow, lower airbox arrangement and fresh-air duct remain where specified. No new MAF, engine sensor, extra filter sleeve or cleaning kit is included. The nine-inch bill hose is called 8-1/2 inches in step 20; check actual routing and slack instead of assuming a different supplied part. The shortened barb wording is ambiguous and must be matched to the actual fitting; do not force it into the wrong grommet.

One oiled main filter, small air-pump breather filter, molded tube, metal shield, aluminum cover, turbo reducer, clamps, MAF gasket/screws, vent hoses/fittings, preinstalled grommets and mounting hardware.
Does it include two full-size intake filters?No. The second filter is the small air-pump breather installed behind the passenger fog-lamp area.
Must the fog lamp and grille be removed?The exact procedure removes them for air-pump access, then reinstalls both after fitting the small filter.
Are all original breather and switch connections retained?Yes. Follow all five illustrated connections, reuse the specified factory elbow and restore the switch-valve plug and MAF plug.
Why does the middle hose need checking?The bill specifies nine inches while step 20 says 8-1/2 inches. Verify actual hose routing, fit and slack before securing it.
What do the legacy performance figures represent?The brochure identifies 12 hp and 20 lb-ft at 2900 rpm on a 2004 A4 and 180 versus 110 CFM at 1.5-inch H2O. Complete test conditions and current-revision equivalence are not provided.
Does the existing 2006 Cabriolet row establish emissions coverage?No. Exact retailer fitment supports retaining that row, but reviewed D-550-30 lists this kit for A4 2002-2005 1.8L turbo. Confirm actual applicable coverage.
What final checks and service interval apply?Restore the fresh-air duct, cover, fog lamp/grille, hoses and electrical plugs. Check all clamps and connections and recheck periodically; no battery step, numeric torque or mileage interval is stated.
Verify aFe 54-10322. Read both pages and all twenty-eight images. Remove and save the fresh-air duct, open the airbox, unplug the MAF and loosen the original tube. Disconnect the five illustrated breather connections while saving the specified factory elbow; disconnect the switch-valve plug only as needed. Remove the tube from the turbo. Remove the passenger fog-lamp grille and lamp, disconnect the air-pump hose at the pump and remove its fitting. Install the supplied small breather filter on the pump, then restore the lamp and grille. Transfer the MAF using the supplied gasket and two M4 screws. Fit the turbo reducer and clamps, place the larger reducer barb near the turbo and shorter barb near the MAF, using lubricant only as directed to ease grommet installation. Align the housing clip and sides with the retained airbox arrangement and secure the turbo connection. Connect the lowest breather to the large barb with a #16 mini clamp. Fit the middle hose/elbow to the next fitting and switch valve and restore its plug; verify the nine-inch bill versus 8-1/2-inch step discrepancy against actual routing. Route the 22-inch hose toward the firewall at the next fitting and use the three-inch hose/elbow at the fourth fitting. Restore the saved factory elbow at the last fitting and clamp to the original metal tube. Align tube and housing with the M6 bolt, nut and flat/wavy washers, reconnect the MAF, install the main filter and aluminum cover, and restore the original fresh-air duct and two screws. Check all clamps, vent and electrical connections and recheck periodically. No battery step, numeric torque or mileage interval is stated.
Current exact primary, the complete two-page manual with all twenty-eight images and both bill columns were reviewed. The exact older manufacturer brochure hosted by ECS was also read and viewed: it documents 12 hp and 20 lb-ft gains at 2900 rpm on a 2004 A4, not separate peak-output differences, and 180 versus 110 CFM at 1.5 inches of water. That ratio is about 63.6%; the brochure labels it 63%. Full run conditions, correction factors and current-revision equivalence are not provided. The brochure specifies a 16-gauge shield while current primary says 18; no gauge revision is certified. Hose length and shortened-barb wording conflicts remain qualified. Exact retailer positives retain original Cabriolet bounds without extending emissions coverage. All eight pages of cached official D-550-30 were reviewed, including Exhibit A listing the selected A4 2002-2005 1.8L turbo kit. Conditions retain manufacturer tuning specifications, prohibit adverse emissions-control changes and exclude installation before or with first transfer of a new vehicle. The order is not endorsement of horsepower, torque, flow or emissions-benefit claims. Confirm the actual kit revision and regulated-use requirements.
