Introduction
The thrill of owning a Lamborghini Urus isn’t just about its exhilarating V8 performance—it’s about preserving the super SUV’s Italian artistry with the best, dealer-issued parts. Today, we’ll spotlight two pinnacle OEM components for the discerning Urus driver: the Lamborghini Urus Catalytic Converter V8 TFSI LK4/5 (LH & RH) silver OEM 4M0254202A – 4M0254252M and the Lamborghini Urus Fender Widening Rear Left & Right Wheel Arch Cover Black OEM 4ML854819B 4ML854820B.
However, not all replacement parts are created equal. Therefore, let’s dig into why you should always choose OEM for your high-performance SUV—keeping its heart, aesthetics, and value exactly as Sant’Agata intended.
Why OEM Parts Matter for Lamborghini Urus
For example, OEM components are meticulously engineered to the exacting standards Lamborghini demands. After all, every contour and component in the Urus must combine luxury, aggression, and functional performance.
In contrast, generic aftermarket parts simply can’t replicate the reliability or precision found in factory-made, dealer-issued original pieces. Choosing OEM parts directly sustains performance, warranty, and investment value.
Meanwhile, using the Lamborghini Urus Catalytic Converter V8 TFSI LK4/5 (LH & RH) silver OEM 4M0254202A – 4M0254252M or Lamborghini Urus Fender Widening Rear Left & Right Wheel Arch Cover Black OEM 4ML854819B 4ML854820B means every curve, weld, and finish fits perfectly, keeps emissions legal, and matches Urus’s original design DNA.
Key OEM Parts Categories and Specifications
Let’s focus on our featured parts and where they fit into the larger Lamborghini ecosystem.
Catalytic Converter V8 TFSI LK4/5 (LH & RH) silver OEM 4M0254202A – 4M0254252M
This official, factory-fresh catalytic converter is purpose-built for the Urus’s twin-turbocharged V8 TFSI engine. Therefore, it meets California and international emissions compliance, while maintaining optimal exhaust flow for maximum performance.
Moreover, being both the left-hand (LH) and right-hand (RH) variants, these converters ensure symmetrical flow characteristics—critical for twin-turbo operation. Lamborghini’s engineering ensures seamless fitment to stock exhaust manifolds and sensors.
- OEM Part Numbers: 4M0254202A (LH), 4M0254252M (RH)

OEM vs Aftermarket: Why Original Wins
Furthermore, originality matters not just for looks—but for safety and value. Aftermarket parts may seem tempting due to pricing. However, they frequently lack rigorous testing and the unique Lamborghini build quality.
Therefore, OEM pieces such as the Lamborghini Urus Catalytic Converter V8 TFSI LK4/5 (LH & RH) silver OEM 4M0254202A – 4M0254252M retain precise tolerances for emissions, noise, and power output. Third-party substitutes may jeopardize warranty and compliance.
Meanwhile, genuine arch covers shield the body’s high-gloss paint, line up flawlessly, and feature anti-fade, impact-resistant coatings exclusive to Lamborghini factory supplier standards.
In contrast, off-brand alternatives might not withstand harsh weather or the daily torque loads your Urus experiences, leading to mounting issues or unsightly gaps.
In summary, OEM equals trust, unrivalled performance, and ultimate peace of mind.
Installation Tips and Maintenance Best Practices
However, even authentic OEM parts demand expert installation for a car of this calibre. Always work with a certified Lamborghini technician—especially for emission and structural body components.
For example, installing the catalytic converters requires specific torque values, sensor calibration, and ECU recognition to avoid engine warning lights. Ask your specialist to update vehicle logs post-installation for full warranty compliance.
For arch covers, always dry-fit the panels before final mounting. Consequently, this ensures perfect gaps and that all fasteners lock as per factory diagrams. Heat-cycle the parts after installation—especially in extreme climates—to confirm expansion tolerances remain true.
Meanwhile, regular visual inspections help spot early corrosion, dirt accumulation, or micro-cracks. Clean both components with pH-neutral products only, and avoid abrasive materials which may affect finish and longevity.
