With intrest I did read the thread started by mobat on Mar 25, 2024 about retrofit 2025 features on 2019-2024 models.
The thread handled mostly MBUX and Keyless-go.
No comments on the less complicated modification of the new aerodynamical trim of the A-pillar and trim on the leading edge of the roof above the windshield?
This modification promises less fuel consumption on the Autobahn and especially less noise at high speed...
Anyone did attempt that or knows if that is possible? And what is the price of the required parts?
I’ve also been looking into this, and managed to find the part numbers for the two pillars and the small spoiler on the roof which will require paint
I have yet to order but I will place it soon.
I have been trying to search how to remove the existing pillar trims to see if this is a snap out snap in, or requires internal trim removal to access. Anyone here been able to remove the a pillar exterior trims?
the part numbers are:
M MA465 690 69 00 7C45 TRIM STRIP £44.5
M MA465 690 70 00 7C45 TRIM STRIP £44.5
M MA465 690 47 00 PARTS KIT TRIM £1172
this one requires painting to match body colour
I am still searching for for the window seals which have the new deflectors in them.
The roof trim/spoiler I have on order it has yet to be fulfilled or is not available yet. The door gaskets were a pain to install but can definitely tell less wind noise.

Can you send a photo of the new gaskets? Do you have part numbers for these?
Tried having the dealer install the new front spoiler on a 21 G63, they said the spoiler is not compatible since the new windshields have a slightly different angle. I call BS, I think they simply didn’t want to deal with it.
Thanks for pointing out the window gasket, that could be a nice quick improvement. Part Numbers? And how was the install? I know the upper portion of the gasket isn’t bad to remove, but the bottom part is a pain in the ***.
Hello, any update on the A-pillar windshield trim to match the 2024 facelift. My goal is to reduce wind noise and improve fuel efficiency by enhancing aerodynamics. Any advice on parts and installation?
As seen above, we can observe the difference in the A-pillars. In the facelift model, the design is more refined and fits seamlessly with the car's frame, whereas in the pre-facelift version, the plastic trim extends from the top in a bulkier design. The question is whether this swap is an easy fit and installation to update the old design with the new more aerodynamic one.
I think these trim pieces have panel bonds applied underneath so any removal would not only take a lot of efforts but possibly cause damage so you have to accept the fact that the pieces may not be saved.
If the trims are ordered from the W465, would they fit directly into the mounting holes of the pillar as seen on the body frame of the W463A? The question is whether there are any changes to the frames.
Following the unanswered topic, I discovered something very interesting: the aftermarket W465 A-Pillar Carbon offered by Gwagenparts is not compatible with the W463A. This raises a new question: could the new model have an indentation in the metal to allow the plastic to fit inside?
UPDATE
I contacted gwagenParts and received an update regarding the A-pillar dry carbon parts. They informed me that the reason these parts do not fit the W463A is due to differences in the structural designs and dimensions between the W463A and W465 models. The W465, being a newer generation, has updated bodywork and frame specifications that are not compatible with the older W463A. This includes variations in mounting points and overall fitment of certain body components, such as the A-pillars.
I just did a side by side yesterday, it appears different but it’s actually the trim piece that’s much larger and the body seems to be the same. What I checked the body frame of the car is the same?
Thanks to everyone for sharing updates—this has been super helpful. It’s interesting to see the different takes on whether the A-pillar differences between the W463A and W465 are structural or just trim-related.
GwagenParts says it’s a frame and mounting point issue, but if the body frame is actually the same and it’s just the trim that's larger or shaped differently, that could change things. Seeing real side-by-side comparisons will be key.
Looking forward to those photos and fitment results. It’ll be great to finally clear this up and know what actually works between the two models.
I’ve gone ahead and ordered the A Pillars, roof spoiler which is part of the trim, and the window seals.
They should arrive tomorrow. I will let you know what I find out if they match up side by side and post photos.
Wish us luck!
You're a legend. Please update us once you've figured it out. Would be great to make these changes. I think the spoiler will be most effective and should be easiest. Would love part numbers and process once you have them in hand and tried installing them. Thanks!
Just picked up the trim pieces on the sides, spoiler coming Monday.
Will post photos later but the new trims are stick on pieces with pre applied sticky tape.
the old ones I’ve checked are clipped on and underneath is a V shaped mounting point over a weld.
it’s going to be a bit more difficult but will see where we get to!
Here is a demonstration of how the A-pillars look — you can see the differences in the angles and curvature. W463A Above - W465 Below
W463A W465
Yes, it's entirely visible when you put the 2 cars next to each other, the entire metal contour and indentations for the trim in the A-pillars are different! You would need major major body work on the A-pillars to fit those pieces of trim!!

Unfortunately, I feel like some fail to realize that Mercedes-Benz is marketing the W465 as a new generation for a reason. Yes, *most* of the body shell is carried over from the previous W463, but they clearly made significant structural changes (such as the A-Pillar structure and electronics) that many have found not to be a "simple swap" and actually would require five figures US in retrofit and mods (and let's be honest, is it worth doing fab work to a body shell in a critical safety structure area like the A-pillar forward? likely not).
If the W465 was really just a "facelift" and nothing more, I feel like this would been much easier and done already.

Yeah, we actually didn’t know there was fab work on the A-pillars , that definitely means there’s no way any swap will be happening.
