AutoTecknic Dry Carbon Performante Rear Diffuser - G20 M-Sport Pre-LCI
The AutoTecknic Dry Carbon Performante Rear Diffuser is purpose-built for the G20 M-Sport Pre-LCI, bringing a more aggressive, track-inspired presence to the lower rear without sacrificing the clean, factory-integrated look the platform is known for.
The enlarged fin design doesn't just look the part — it adds functional depth to the rear bumper profile, giving the M340i the visual aggression typically reserved for full M cars. Installation is straightforward, integrating directly into the factory lower rear bumper with no cutting, no modification, and no compromise on fitment.
Built using AutoTecknic's signature 100% true pre-preg dry carbon process, every diffuser is laid up with impregnated carbon material, placed into a precision mold, and autoclave-cured under controlled heat and pressure. The result is a part that's lighter, structurally stronger, and dimensionally more consistent than anything produced using the traditional wet-lay method. Fewer voids, fewer imperfections, and a flawless gloss finish that speaks for itself.
