Follow these steps carefully
X6 xDrive40i (B58 3.0L turbo): the air filter is in the airbox in the engine bay — a large black box, usually on the driver's side. BMW uses a TORX-SCREW lid (T25 typical — verify). Don't confuse it with the cabin filter.
Remove the Torx screws securing the airbox lid — count them so you don't miss one. The intake tube may be attached to the lid; you can often lift it enough without fully disconnecting. Set the screws aside safely (don't drop them into the bay).
I've been burned enough times that I always count the screws as they come out — on a Torx-sealed airbox, one forgotten screw warps the lid and you get an intake leak the MAF can't compensate for. Every screw goes back.
Lift the old panel filter out. Note the orientation. If the filter is dirty, that's costing your X6's B58 power — the turbocharged 3.0L is sensitive to restriction. Check for debris in the airbox.
Wipe the airbox housing clean with a rag. Remove dust and debris. Check the airbox seal — the B58's turbo system needs a perfect intake seal (boost leaks hurt). Don't touch the MAF sensor in the intake tube.
Install the new panel filter, matching the old one's orientation. Ensure it seats flat with no gaps. The B58's airbox is precision-fit — the filter should drop in perfectly. A misaligned filter causes unmetered air (the MAF won't compensate correctly).
Replace the airbox lid and reinstall all Torx screws — tighten them evenly (don't over-torque the plastic). The lid must seal — the B58's intake is pressurized by the turbo, so leaks matter. Close the hood and start the engine; it should idle smoothly.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
