What MS Motorservice makes and sells

MS Motorservice International GmbH is the global sales organisation for the independent automotive aftermarket activities of Rheinmetall's Power Systems business, the former KSPG (Kolbenschmidt Pierburg) automotive sector. It is a distributor and channel operator rather than a single-plant manufacturer: it takes engine components built to original-equipment (OE) standards and supplies them to trade and repair-shop customers in more than 130 countries. The company sells under five brands, the premium marques Kolbenschmidt, Pierburg and TRW Engine Components alongside BF and turbo by Intec.

The product range covers parts both in and on the engine. Kolbenschmidt supplies pistons, piston rings and engine bearings. Pierburg covers air and emissions hardware, exhaust-gas recirculation (EGR) valves and coolers, exhaust-gas flap modules, secondary-air systems, water and coolant pumps, oil and vacuum pumps, and a growing sensor line (oil pressure and level, NOx and lambda, pressure sensors). TRW Engine Components supplies valves, valve guides and seats, and turbo by Intec covers remanufactured turbochargers. Recent additions show the electrification tilt: in early 2026 the company added a Pierburg filter-dryer kit for Tesla Model 3, Y, S and X covering more than 3.7 million vehicles, and an electric air-conditioning compressor in OE quality for hybrid Toyota models. Motorservice also runs an Original Equipment Services (OES) channel, supplying replacement parts back to OEM automotive customers, and produces small-series aftermarket pistons in Kolbenschmidt series quality at its Chabarovice plant in the Czech Republic, roughly 6 km from the Kolbenschmidt OE line.

Financial performance

The Motorservice Group reported turnover of 583.4 million euros and 1,104 total employees as at December 2025, per the company's own facts-and-figures disclosure. That places it firmly in the mid-market band for automotive aftermarket sales organisations. As a subsidiary consolidated within Rheinmetall, MS Motorservice International does not publish a standalone balance sheet, so this profile does not assign a financial-resilience or trend grade. The group operates through subsidiaries in Germany, the Czech Republic, France, Spain, Italy, Turkey, Brazil, China and Singapore, giving it distribution reach across Europe, the Americas and Asia.

Ownership and history

The Kolbenschmidt and Pierburg brand lineage runs more than 100 years. MS Motorservice International GmbH is the modern group sales entity, registered at the Stuttgart district court under HRB 105964 and headquartered at Wilhelm-Maybach-Strasse 14-18 in Neuenstadt am Kocher, Baden-Wurttemberg, with a second German location in Dormagen.

Ownership is in transition. Rheinmetall, which has been refocusing on its defence business, put its civilian Power Systems division up for sale, and on 3 June 2026 signed an agreement to sell it to the Munich investment firm AEQUITA for about 350 million euros, with closing expected in the fourth quarter of 2026. The Motorservice, Kolbenschmidt and Pierburg brands continue under their established names, and AEQUITA said it will retain the roughly 6,250 Power Systems employees. Piston production units had already been divested over 2023 and 2024. Executive management is led by Regis Serrano, who became CEO on 1 February 2025 after serving as senior vice president of aftermarket sales, succeeding the retiring Tobias Kasperlik; Ulrich Schrameyer serves alongside him in executive management.

Certifications and quality

The Motorservice Group is certified to ISO 9001:2015 for quality management and ISO 14001 for environmental management, per the company's disclosures, with an ISO 9001 certificate posted on its site. Because most of what the company sells carries the OE-heritage Kolbenschmidt, Pierburg and TRW Engine Components brands, quality positioning centres on OE-equivalent specification and forgery-proof holographic packaging rather than shop-floor process certificates. Buyers evaluating the parts through a structured PPAP or APQP lens should note that the OES channel is the route for OE-program supply, while the branded aftermarket range is specified to OE-replacement standards.

Known customers

Motorservice sells into the independent aftermarket, so its customers are distributors, parts wholesalers and repair shops rather than named vehicle programs. The company states it serves customers in more than 130 countries. Through its OES channel it also supplies replacement parts to OEM automotive customers as an original-equipment service, though specific OES accounts are not publicly named. The published vehicle-application coverage is a better signal of relevance than any single account: individual new parts routinely cover millions of vehicles in the car parc, from the 3.7 million Teslas addressed by the 2026 filter-dryer kit to the 93 million cars covered by the Pierburg oil-level sensor range.

Sourcing evidence

MS Motorservice appears in US customs records with a small ocean-freight footprint: 17 US import shipments on record, the most recent dated 20 August 2026. The named top supplier is Pierburg Pump Technology Mexico, the group's own Mexican pump plant, which is consistent with intra-group movement of Pierburg pumps rather than third-party sourcing. This is the expected pattern for a European aftermarket distributor whose primary flows are within Europe and to trade customers worldwide: most of its logistics do not touch US ocean freight and so do not appear here.

Coverage caveats: these are US ocean-freight bill-of-lading records only. Air, truck and rail movements, and most non-US flows, do not appear; some records name freight intermediaries rather than manufacturers; and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence. For buyers weighing nearshoring or European-sourced aftermarket supply, the group's multi-country subsidiary network matters more than its thin US import trail.
