The Saab 9-3 rear diffuser, a part coveted by enthusiasts for its distinct design and functionality, is making a much-anticipated return. Thanks to KM-tronics, a Saab OEM parts specialist, this iconic component—known officially as PN: 32025847—is being carefully replicated for modern production. While Saab ceased manufacturing over a decade ago, KM-tronics has undertaken the task of bringing this essential part back to life with modern materials and innovative methods.

Faithful Replica Based on the Original Design
To ensure authenticity, KM-tronics founder Mark van Kampen started with an OEM diffuser from one of his own Saab 9-3s, which he meticulously 3D scanned to create a digital model. Using this data, KM-tronics developed a polyurethane (PU) mold, which is now being used to produce prototypes for rigorous testing.
Mark explained the process:
“Once we confirm the prototypes are strong enough and meet all requirements, we will move to an aluminum mold for the final production version.”
This modern production method ensures the replica diffuser will retain the original’s design and functionality while offering greater durability thanks to improved materials.
A Modern Solution to a Long-Standing Problem
The original PN: 32025847 rear diffuser has been out of production for years, leaving many Saab 9-3 owners struggling to find a replacement. KM-tronics’ replica is not just a cosmetic addition—it’s a functional and structural enhancement for the vehicle, designed to meet the demands of both daily driving and high-performance use.
The updated diffuser will be compatible with single-exit exhaust systems and can accommodate exhaust pipe sizes of 2 inches or 2.5 inches, providing flexibility for enthusiasts who have customized their vehicles.
Overcoming Challenges in Production
Replicating such a detailed and complex part has presented significant challenges. The straight stripes and notches in the diffuser’s design required precise 3D modeling and engineering to replicate accurately. KM-tronics has conducted thorough prototype testing, ensuring the replica diffuser can withstand temperatures up to 130°C and remain durable at speeds of up to 250 km/h.
Mark and his team are committed to maintaining OEM-level quality while incorporating modern materials to improve the durability of the part.
Expected Availability and Pre-Orders
KM-tronics aims to complete prototype testing by the end of November 2024. If the results meet expectations, full-scale production will begin using the aluminum mold, with the first units available for delivery by January 30, 2025.
Pre-orders are now open via KM-tronics’ official website, offering Saab enthusiasts the chance to secure this rare and essential component for their vehicles.
