Optimize Intake Velocity for your Audi A6 & A7 EA839 and EA897 V6

Who It’s For: Designed specifically for 2018 and newer Audi A6 (4A) and A7 (4K) owners running the EA839 3.0L TFSI or EA897 3.0L TDI engines. If you’re looking to improve throttle response and turbo spool-up without the noise of an open intake, this is the professional choice.

The Problem: The factory paper filter in the EA839 and EA897 V6 is designed for long service intervals and cost-savings, not performance. These thick paper elements create significant air resistance, forcing the turbocharger to work harder to pull air through the pleats. This leads to increased intake air temperatures and a noticeable lag in throttle tip-in.

The Solution: This BMC performance filter uses a multi-layered cotton gauze system soaked in low-viscosity oil. By reducing filtration restriction to 7 microns (compared to the 10-micron OEM standard), we allow a higher volume of air to reach the turbocharger while maintaining superior engine protection. We engineered this part to correct the factory design flaws of the stock airbox, delivering reliable performance and a lifetime of use.

Why This is the Ultimate Upgrade

  • Enhanced Flow Dynamics: Increases air volume to the intake manifold, allowing the EA839 and EA897 engines to breathe more efficiently under boost.
  • Full Moulding Construction: Produced using a single-mould system with no welded joints, eliminating the risk of the filter frame cracking or failing under high-pressure scenarios.
  • Washable & Reusable: Unlike disposable paper filters, this unit can be cleaned and re-oiled using a standard regeneration kit, making it the last filter your Audi will ever need.

Installation & Tools

The Wrench Time

  • Estimated Time: 20-30 Minutes
  • Difficulty: 2/10 - Straightforward driveway maintenance with zero specialty lifts required.

Tools You Will Need

  • T25 Torx driver (or 1/4" drive ratchet with T25 bit)
  • 7mm socket or flathead screwdriver (for intake tract hose clamps)
  • Small flat-blade pocket screwdriver or precision pick tool (for Audi harness lock tabs)
  • Panel popper tool (optional, for engine shroud clips)
  • Microfiber towel and shop vacuum (for cleaning debris from bottom of the airbox)
Mechanic’s Pro Tip (The "Gotcha"):
On the 2018 Audi A6 A7 airbox lid, the factory T25 Torx screws are semi-captive, but if backed out too far they will drop straight into the abyss of the lower belly pan. Back them out evenly until you hear them click past the threads without pulling them completely out of the upper lid. Additionally, the breather vacuum line quick-connect on the intake tract gets brittle from turbo heat cycling—squeeze the textured ring firmly with your fingers; never pry the collar with pliers or you will crack the plastic nipple.

Phase 1: Removing the Factory Part

  1. Disconnect the Battery: Pop the trunk, lift the floor panel, and disconnect the negative terminal using a 10mm wrench to prevent errant ECU codes while working around intake sensors on your 2018 Audi A6 A7.
  2. Remove the Engine Cover: Pull straight up on the front corners and then the rear corners of the plastic decorative engine cover to pop it off its ball-stud mounting grommets. Set it aside on a soft surface.
  3. Release the Sensor Harness & Breather: Locate the Mass Air Flow (MAF) or Intake Air Temperature (IAT) sensor on the intake elbow. Slide back the grey locking tab with a small flat-blade pocket screwdriver, press down on the release clip, and disconnect the harness. Carefully depress the ribbed release ring on the vacuum breather line and pull it straight off the intake tract.
  4. Loosen the Intake Inlet Duct: Use a 7mm socket or flathead screwdriver to loosen the worm gear clamp securing the flexible intake accordian tube to the airbox housing. Slide the tube off the airbox neck.
  5. Unbolt and Lift the Airbox Lid: Loosen the perimeter screws on the airbox using a T25 Torx driver. Tilt the lid upward from the front, unhook the rear hinge tabs from the lower airbox base, and set the lid aside. Lift out the restrictive OEM paper filter element.

Phase 2: Installing the Performance Air Filter

  1. Prep and Vacuum the Airbox Base: Before dropping in your new performance filter, use a shop vacuum and a clean microfiber towel to clear out leaves, sand, and road grit trapped in the lower airbox tray.
  2. Seat the Performance Filter: Align the new Performance Air Filter with the perimeter channel inside the airbox housing. Press down along the entire rubber sealing gasket with your fingers to ensure it seats completely flush in the lower airbox grove; an unseated lip will allow unmetered, unfiltered air past the seal.
  3. Reinstall the Airbox Lid: Slide the rear retaining hinge tabs of the airbox lid into the corresponding slots on the lower base first. Lower the lid flat, ensuring the filter gasket remains pinched squarely inside the housing. Hand-thread the perimeter screws, then tighten them down snug in a criss-cross pattern using a T25 Torx driver (do not overtighten into plastic).
  4. Reconnect Intake Plumbing & Sensor: Reattach the intake accordion tube onto the airbox outlet neck and tighten the clamp firmly with your 7mm socket. Push the vacuum breather line back onto the bung until you hear an audible click. Plug the sensor harness back in and slide the grey locking tab forward to lock it into place. Reinstall the top engine cover by pressing down over the ball-stud grommets.
  5. ECU Adaption Startup: Reconnect the battery negative terminal using your 10mm wrench. Start the vehicle and do not touch the gas pedal for at least 20 seconds. Allow the 2018 Audi A6 A7 ECU to idle smoothly and adapt its MAF/MAP trim tables to the increased airflow before driving.
