Carbon Fiber Rear Diffuser for Mercedes-Benz Under Panel E-Class W213 E300 E350 E450 4-Door (2020-2021)

It replaces the plain lower valance on the Mercedes-Benz Under Panel E-Class W213 E300 E350 E450 4-Door (2020-2021) with a finned diffuser that cleans up the airflow leaving the rear bumper.

Carbon fiber – not a hydro-dipped or printed film. You can see the weave shift as the light moves across the surface.

Fits: Mercedes-Benz Under Panel E-Class W213 E300 E350 E450 4-Door (2020-2021)

Moulded from the Mercedes-Benz Under Panel E-Class W213 rear bumper profile so the outer edges meet the bumper corners cleanly.

Undo the lower bumper fixings, offer the diffuser up, and re-use the original screws where the holes align – about an hour.

Quad-exit and single-exit cars use different cut-outs – confirm from the listing photos which bumper your car has.

Weave, finish and edge treatment are all chosen when you order: glossy 3K twill is the default, while matte, forged carbon, coloured clear coat and carbon-kevlar hybrids are produced on request.

• 3K twill, 6K twill, plain weave or carbon-kevlar hybrid
• Coloured tinted clear coat (red, blue, yellow)
• Logo application or badge cut-outs on request
• Gloss, matte, satin or forged carbon finish

Rinse road salt and brake dust off regularly and wipe with a pH-neutral cleaner; a light wax keeps the clear coat glossy and stops dust bonding to the weave.

We are the workshop, not a reseller. Yeedercar runs its own composite shop in Shishan, Nanhai, Foshan – roughly 1,000 m2 with an autoclave, a dust-free paint booth, CNC trimming and vacuum-bagging stations, plus twelve engineers and technicians who average eight years on carbon.

Every unit is checked against a photo checklist – pinholes, weave alignment, mounting-hole position and clear-coat flow – before it is packed.

For bulk orders we quote from your drawing, scan or sample part; new tooling usually takes 15-25 days, then each batch runs in 20-35 days depending on quantity.

Made to order in our workshop, typically 10-15 business days before it ships worldwide with tracking, backed by a 12-month warranty against manufacturing defects.

In the box: diffuser, screws, clips and a fitment card.
