Tesla Model 3 and Model Y Interior Upgrades Worth Fitting

A Tesla cabin looks finished the day it leaves the factory, but "finished" and "fitted to how you actually use the car" are two different things. There's no glovebox latch to muffle and precious little trim to personalise, so the accessories that matter aren't about adding gadgets — they're about closing the gaps between a showroom cabin and a daily-driven one: comfort on long stints, protection on the surfaces that take the most contact, and storage for a car with no traditional glovebox. The full range for Model 3 and Model Y sits in our Tesla accessories collection, but this guide goes narrower than a general "must-have" list, into the material and fitment details that decide whether an upgrade is worth fitting.

Comfort upgrades that don't fight the minimalist cabin

Tesla's factory seats are firm and flat-profiled, which suits short trips but leaves plenty of drivers reaching for extra support once a drive passes the hour mark. Fit anything shaped for the car's specific headrest and seatbelt geometry, since the Highland and Juniper redesigns changed headrest angles and seatbelt anchor points from the earlier shape.

Tesla Neck Pillow & Matching Seat Belt Pad Set

A seat belt pad paired with a neck pillow is a two-minute fix for a strap that digs into the collarbone on longer drives. Foam density matters more than fabric here: a pillow too soft collapses under the head's weight within twenty minutes, while one too firm just relocates the pressure point.

Tesla Headrest & Lumbar Support Pillow SetTesla Suede Headrest Pillow, Neck SupportModel 3 & Y Centre Console Armrest Cushion

The armrest lid is one of the most overlooked wear points in the cabin — an elbow rests there on every drive, and the factory pad is thin enough to flatten and shine within a year or two of daily use. A padded cover adds real thickness back into that contact point rather than just a cosmetic layer.

Summer creates a separate problem. A black interior in direct sun for a few hours in an Australian summer regularly pushes seat surface temperatures well past comfortable, and factory upholstery doesn't breathe fast enough to fix that alone.

Tesla Ice Silk Breathable Seat Cushion

Ice-silk fabric doesn't actively cool anything, but its tight weave wicks moisture away far faster than factory trim, which is what creates the cool-to-touch feeling. It's a passive fix with no cable to run, which suits a console with limited spare 12V or USB-C capacity to begin with. Our guide to ice-silk and cooling cushions covers the fabric in more depth.

The steering wheel: the surface you touch on every drive

Nothing in the cabin gets more direct hand contact than the wheel, and the factory vegan leather shows it — sunscreen, sweat and constant grip wear it faster than almost any other trim piece, with no factory option to swap it out. Material choice changes the outcome more than most owners expect.

Tesla Suede Steering Wheel Cover, Anti-SlipTesla Carbon Fibre Leather Steering Wheel CoverModel Y Steering Wheel Suede Trim Panels

Suede covers give the most grip, since the napped surface bites into skin even when hands are slightly damp — genuinely useful on a humid drive or after a workout. The trade-off is that suede holds dirt and body oils more readily, so it needs a wipe-down more often to avoid looking patchy.

A carbon-fibre-look leather cover trades some of that raw grip for a smoother, easier-to-clean, more premium finish. Genuine leather ages the most gracefully of any cover material under UV exposure through the windscreen, developing a light patina rather than cracking. Cheaper PU-leather covers do the opposite: the plasticisers in the coating break down under UV and heat, so they harden and crack within a year or two of Australian summer sun. If a full cover feels like overkill, trim panels dress up the spokes without changing the grip surface at all.

Protecting the parts that wear out of sight

Some of the fastest wear in the cabin happens on parts owners rarely think to protect, because the damage builds slowly.

Silicone Rearview Mirror Cover, Anti-GlareSilicone Door Lock Covers, Set of FourTesla NFC Key Case, Shell Cover & Protector

The door lock actuators around the exterior handles sit exposed at bumper height, where road spray and dust collect over time. A silicone cover keeps debris out of the mechanism without affecting how the handle presents or the sensor reads. The auto-dimming rearview mirror housing is similar — a silicone cover with an anti-glare edge stops keys, sunglasses and jewellery from scuffing the glass while cutting high-beam glare from tailgating traffic at night, without interfering with the automatic dimming function.

A key case addresses a specific, verifiable risk rather than general wear: Tesla's NFC key cards and phone-key system communicate over short-range wireless signals, and keyless relay attacks — where a signal is captured and amplified to unlock and start a car without the key physically present — are a well-documented risk across the industry. A case with a shielded lining blocks that signal when the key isn't in use.

Model Y Rear Seat Air Vent Protection CoverSeat Belt Plug Kit, for Unoccupied SeatsModel 3 & Y Air Vent Diffuser Clip

The rear cabin vents on the Model Y sit low on the console and rear door trim, right where dropped food, spills and small toys land in a car with kids. A fitted vent cover stops debris falling into the housing, which is cheaper than clearing a blocked vent fan later. The seat belt plug kit solves a different annoyance: the chime that nags for an unclipped belt on any seat it thinks is occupied, which gets old fast if you regularly carry gear rather than passengers on the back seat. This is strictly for genuinely empty seats — never plug a buckle a passenger is meant to use, since the belt won't restrain anyone if it isn't actually fastened around them. A vent-clip diffuser rounds this out: a small, refillable scent clip that skips sticky gel pucks and sits neatly out of the airflow.

Storage for a cabin with no traditional glovebox

The boot and frunk combination is genuinely useful, but the load area has none of the tie-down points or carpet a traditional wagon boot has, so items slide unless the space is set up properly.

Model Y Waterproof TPE Cargo Liner MatModel Y Retractable Trunk Cargo Cover

A moulded TPE liner does two things carpet can't: it's fully waterproof, so a wet umbrella, muddy shoes or a leaking bag of ice doesn't soak into the trim underneath, and its raised lip contains spills rather than letting them run into the seams around the load floor. Carpet feels plusher underfoot but absorbs odour and moisture over time in a way TPE doesn't. A retractable cargo cover pairs well with either liner — it keeps the boot's contents out of view through the rear glass, useful for both privacy and as a basic deterrent against opportunistic theft when parked in public.

Where an aftermarket display actually adds something

It's a fair question why a car with a large centre touchscreen would need another display bolted to the dash. The honest answer is that Tesla's software still doesn't support Apple CarPlay or Android Auto natively, so owners who rely on Apple Maps or CarPlay's steering-wheel-friendly interface have no built-in way to get it.

9.6-inch Display with CarPlay & Android Auto Mirroring

A supplementary display like this mirrors a connected phone's CarPlay or Android Auto interface independently of Tesla's own system — genuinely the only way to run either in the car at all. It suits owners who've specifically missed CarPlay from a previous car, rather than being something every Model 3 or Model Y needs, since Tesla's native maps and media are perfectly usable on their own. For more on choosing dash-mounted tech sensibly, our guide to dash cams and head-up displays covers mounting position and what actually earns its spot on the dash.

Getting the priority order right

Not every owner needs all of this at once. Start with whichever pain point you already feel: a sore neck points to the pillow and armrest fixes first, a tired-looking wheel points to a cover, and a boot full of loose gear points to the liner and cargo cover. Protection items — lock covers, mirror cover and key case — are worth doing early regardless, since they're cheap relative to the parts they protect and the wear they prevent can't be undone once it's happened. For a broader first-accessories list, our must-have Tesla accessories guide is a good companion read, and if resale condition is part of your thinking, our guide on protecting a Model Y or Model 3's trade-in condition goes deeper on that angle.

Whatever you choose, check the listing matches your exact model and build. The Highland refresh for Model 3 and the Juniper refresh for Model Y changed headrest shapes, console dimensions and vent positions from earlier versions, so a part built for one won't always fit the other. The full Tesla accessories range is filtered by model, which is the fastest way to avoid a fitment surprise.

Frequently Asked Questions

A well-set-up Model 3 or Model Y cabin isn't about adding more to a car that's deliberately minimalist. It's about protecting the surfaces that wear fastest, adding comfort where the factory seat falls short, and solving the couple of genuine gaps — storage and CarPlay — that come with the design. Fit a few of these in the right order and the cabin stops feeling like a showroom car and starts feeling like yours. Browse the complete Tesla accessories range to build your own setup.
