Gloss Black FRP Rear Diffuser for BMW 1 Series E82/E88 M Sport
Refine the lower edge of the rear bumper with a gloss black replacement-style diffuser. This part is specified as fiberglass-reinforced plastic (FRP), not carbon fiber, and is intended for the bumper and exhaust layout described below.
Listed fitment
- BMW 1 Series E82 Coupe and E88 Convertible, 2-door, model years 2008–2013, with the M Sport/M Tech rear bumper.
- The original description lists 118i, 120i, 125i, 130i and 135i, but engine badge alone does not establish fitment. Check the actual M Sport bumper and exhaust opening against the product photos.
- Original exclusion: not for E82/E88 base-model rear bumpers. The source specifies “Single Exhaust Twin Outlet bumper”; verify your exhaust tip and diffuser opening configuration before ordering, as that wording does not define every possible layout.
- Fitment for other bumper styles, exhaust configurations or body styles is not confirmed.
Material and finish
- Material: FRP fiberglass.
- Appearance: gloss black, according to the original title; the original description also lists a double-layer UV-protected clear coating.
- Placement: lower rear bumper diffuser insert.
Installation
The original details describe replacement-style installation with self-tapping screws included and recommend professional installation. Test-fit the diffuser and verify the exhaust opening and bumper fastening points before mounting. Self-tapping screws may require drilling; do not assume a no-drill fit. No aerodynamic test figures are provided, so performance gains are not claimed.
Frequently asked questions
Will it fit a base bumper? No, the original listing expressly excludes E82/E88 base-model bumpers.
Will it fit every 135i or E88? Confirm the M Sport rear bumper and the specified exhaust outlet arrangement before ordering.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.
