Warranty & Disclaimer

No warranty is provided on this upgraded product because:

The cooling system must be fully upgraded to a reinforced version.
Proper ECU calibration (tuning) is necessary for safe operation at high boost or extreme power levels.
Supporting components (fuel system, turbo, intercooler, oil cooling) must match the engine power target.

Despite the lack of warranty, we provide a material guarantee on all components, ensuring high-quality materials and manufacturing for longevity and performance.
