Shifts in consumer demand drive industrial restructuring. Compared with radical widebody kits and heavy powertrain modifications, orders for OEM-style upgrade parts for Mercedes-Benz, BMW, Audi and Porsche low-trim vehicles have risen to 65% of total sales. Enterprises focusing on OEM replica tuning parts have achieved steady revenue growth, forming a core counter-cyclical segment of the industry.
OEM upgrade kits replicate factory parts fitted on high-spec trims and enable non-destructive installation on base models. The product range includes ventilated & heated seats, OEM large touchscreens, ambient lighting, sport body kits, wheels, soft-close doors, steering wheel control buttons, adaptive headlights and more. Installation requires no damage to original vehicle wiring, passes annual vehicle inspections smoothly, and fully complies with the regulatory trend of legalized modification under new policies.
Research data from leading domestic tuning suppliers shows four best-selling items across shops: ventilated seats for Mercedes-Benz E-Class & S-Class, fragrance systems for BMW 5 Series & 7 Series, soft-close doors for Porsche Cayenne, and dynamic taillights for Audi A6L. Their repeat purchase rate far exceeds that of competitive aerodynamic performance kits.
The core technical threshold for such parts lies in matching the vehicle’s original ECU data. Small and medium manufacturers lack access to factory communication protocols, resulting in frequent fault codes and malfunctioning features after installation. Leading brands have established dedicated electronic R&D teams to decode German automotive bus protocols. Their plug-and-play accessories are fully controllable via the original vehicle infotainment system, and suppliers also provide supporting programming equipment and technical tutorials along with product shipments.
