Step-by-Step Instructions

Follow these steps carefully

First, confirm the filter exists for your Supra

The 2020–2024 GR Supra (A90) shares its HVAC hardware with the BMW Z4 — not a conventional Toyota, so don't expect a conventional filter location. Toyota dealers stock the cabin filter; confirm the right application with your VIN before buying.

Understand why it isn't behind the glovebox

Unlike nearly every other Toyota, the Supra's cabin filter isn't behind the glovebox — the glovebox can't simply detach. The filter lives under the passenger-side dash, BMW-style, reached from the footwell; plan on working on your back with a flashlight.

Get under the passenger dash and find the trim panel

Slide the passenger seat back, lie across the footwell with a flashlight, and look up under the dash. Release the two quick-release tabs on the trim panel, lower it to expose the filter cover, and photograph everything before touching it.

Clear the hoses before touching the cover

Several hoses and wires clipped across the cover must be moved aside first. Ease them out of their clips gently; don't disconnect anything you don't have to. The BMW-sourced plumbing gets brittle with heat age.

Remove the cover and inspect what you find

Remove the cover and slide the old filter out — don't be shocked if the slot is empty; some owners found the filter was never installed. Note the airflow arrow direction and check for soot or leaves.

🔧 Mechanic's note — Tom Becker

In my experience, If you reach the housing and the fasteners don't look like what you expected, stop — the BMW-sourced cover differs from Toyota diagrams and forcing a plastic tab snaps it. The dealer's VIN-specific parts diagram is worth the two minutes.

Fit the new filter and button everything up in reverse

Slide the new filter in with the airflow arrow matching the old one, refit the cover, re-clip every hose and wire, and re-seat the trim panel until both tabs click. A half-seated panel rattles over every bump.

🔧 Mechanic's note — Tom Becker

From my bay, Some of these cars shipped with no filter installed at all, so don't assume a missing filter means someone took it. Fit a new one and set a 15,000-mile interval.

Verify airflow and set your interval

Start the car and run the fan from low to full on fresh air — airflow should be strong and even, with no whistles or rattles. Replace every 15,000 miles or two years; if service history is unknown, check now.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Hunting behind the glovebox — the A90's filter isn't there; you'll waste an hour and risk breaking dash trim.
• Yanking the trim panel without finding the two quick-release tabs — the tabs release first, then the panel drops.
• Forcing hoses aside instead of unclipping them — the BMW-sourced plumbing gets brittle with heat age; unclip, don't yank.
• Assuming the filter is present — check the slot; owners have found empty housings where a filter should have been.

⚠️ Safety First!

• Ignition off and key out before you start — the blower and its wiring sit right where your hands will be.
• If anything under the dash doesn't match the dealer's diagram for your VIN, stop and confirm before forcing a fastener — the A90's BMW-sourced HVAC doesn't forgive forced clips.
