Description
This high-performance intercooler, OEM part numbers 276000415 / 276000397, is an intake air cooler for supercharged engines. It cools the air leaving the compressor before it enters the engine and replaces a defective cooler when restoring the supercharging system. The original product sheet describes it as a "Riva-type" model, without confirmed manufacturer identification. The Rotax 1503 and Rotax 1630 engines are listed in the product data; this does not mean it is suitable for all versions. Check the applications and installation below.

Why Replace the Intercooler?
A damaged or leaking cooler can disrupt intake air cooling and engine operation. A loss of performance is not enough to identify the intercooler as the cause of failure: a diagnosis of the supercharging and cooling systems is required. The following points warrant inspection:
- Leak or loss of sealing detected on the cooler
- Visible corrosion or damage
- Damaged fittings or signs of leakage
- Abnormal intake temperature or performance loss requiring diagnosis
Inspect the cooler and its connections during maintenance and seasonal commissioning. Follow the manufacturer's flushing and maintenance instructions. Replace a defective intercooler after identifying the cause and check the tightness of the assembly before use.

These parts are related to the maintenance of the supercharging system and bear the corresponding Rotax 1503, Rotax 1630, and Williams 520 tags. However, check their own applications: the 16-tooth kit and the Ø137 mm wheel are not necessarily suitable for all compressor installations or all models equipped with this intercooler.
