The Rotax 1503 and Rotax 1630 engines are listed in the product tags. This does not mean that these hoses are suitable for all versions: the intercooler mounting, shapes, and connections must be compared with those of your installation.
No additional Williams compatibility is specified on this product sheet or in its tags; do not assume a Williams application based solely on the engine or the related products shown below.
⚠️ Always check your serial number (VIN) and the original OEM reference before ordering to confirm exact compatibility with your model.
Why Replace Intercooler Hoses?
Cracked, deformed, or poorly sealed hoses can cause an air leak in the supercharging system. However, a loss of power requires a complete diagnosis before attributing the fault to the hoses. Inspect the following points in particular:
- Visible cracks, cuts, or deformations
- Deterioration of the ends and clamping areas
- Identified air leak in the system
- Hose disconnected or no longer fitting properly on its connection
Check the hoses and their mountings during maintenance and before seasonal commissioning. Replace damaged components and check the installation for leaks after servicing. Choose the variant corresponding to the hose to be replaced, or the pair if both components are required.
