ALTA Intercooler Couplers - MINI Cooper S (R53) - Supercharged
ALTA Performance builds its reputation on tightening up the weak points OEM engineers left behind, and the factory intercooler couplers on the supercharged MINI Cooper S are a classic example. These ALTA couplers replace the thin, heat soaked factory rubber with high temp silicone construction, giving the charge piping a more durable connection that resists cracking and boost leaks over time.
This listing covers the MINI Cooper S (R53) supercharged engine, SKU AMP-ENG-303RD. The couplers are also available in Black (AMP-ENG-303BK) and Blue (AMP-ENG-303BL) colourways via the variant selector on this listing page, so you can match them to your engine bay theme.
Key Features
- High temp silicone construction
- Direct replacement for factory intercooler rubber connectors

- Available in Red, Black or Blue
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please ensure your vehicle's year and engine configuration are confirmed before ordering.
