The first-generation MINI Cooper S (2002–2006 R53) is beloved by enthusiasts for its supercharged punch, go-kart handling, and tuning potential.

That’s where the SneedSpeed engine rebuild kit for MINI Cooper comes in — a complete solution to restore your engine’s performance and reliability, using upgraded components designed for longevity and spirited driving.
