For everyone reading; The ‘spare’ plastic piece lines up with the six tabs on the bottom edge of of the diffuser. Even if it doesn’t belong with your model, it will give extra rigidity. It supports wiring and other stuff on some models like my S205 C250d. It simply clips onto the tabs. Easy!

[@BassGods]

Ended up getting this Same Diffuser for free, (long story). Put it on sunday, and it took me less time than I thought it was gonna be.With a little bit of help of course. Looks spectacular. Thanks Flexx!

I've watch this video months ago, because I wanted to install a carbon fiber diffuser on a 2017 AMG C43 Conv. Great video and it helped me to get a good idea about a diffuser install, but for what it is worth I had to remove the complete rear bumper for a clean install. Keep up the good work Flexx

[@TheFlexxGarage]

Yeah. My diffuser wouldn’t snap in well and it would of been easier if I removed my rear bumper but if I have to remove one less thing, it’s fine by me. I was able to pound the diffuser with my hand for the tabs to snap into place.

[@FinleyESB]

That bit that you couldn't work out where it went sits flat on the back of the diffuser, it holds the aerials for GPS and DAB. it also helps to stiffen up the diffuser

I would have never used a zip tie because that looks cheap and not professional. Instead use automotive bolt with a nut and that would look better and more secured. That's what I did when I installed the E63 diffuser on my 2016 E400. Rivets can be a pain and I rather used nuts and bolts. Overall the new diffuser with the gloss black quad pipe tips look awesome! Nice going Flexx! 👍

[@TheFlexxGarage]

It’s not coming off. I’ve had zip ties on 3 diffusers in my past cars. Plus..I don’t care about clean install. Nobody is crawling under my car anytime soon to judge my work. Hahaha

Great video. So that black part is so you can mount plastic piece that you need to transfer from original diffuser so you can have place to use oem bolts under the car. So yeah you can use rivet or extra bolts to join oem plastik and new one you recieve with diffusor.

[@Krikemancer]

Hey nice vid 👌🏻 Do you know how to remove the rear bumper trim as well? Diffuser on diesel model.

[@andrevenancio]

Got the same kit, bumped into the same issues as you, but it looks gorgeous. I took the bumper out and put brackets alongside the diffuser cause the clippers in the diffuser aren’t deep enough.

[@TheFlexxGarage]

Yeah...I went back and did some more "slapping" and I finally got mine to all clip in. It's definitely easier to clip in if the bumper is off but I just hate removing body panels. They always take awhile and sometimes they never align perfectly when putting back on the car. I guess I'm just lazy. hahahaha

nope. It's just the tips. The 2 hanging hooks that I installed onto the plastic bracket...those hooks are not the same length..that's why the tips hands uneven. That's the nature of aftermarket parts. They'll never be perfect like OEM. I can probably take off the tips and bend the hanging hooks but i dont care.
