Character

M97

"997 Carrera. IMS issue mostly solved in 2006+ (larger bearing). Bore scoring still possible but less common. More refined than M96. DFI on later 997.2 (MA1 series) eliminated IMS entirely."

9A1/MA1

"991 Carrera NA and 997.2. Direct fuel injection. No IMS bearing. No bore scoring concern. Porsche's most reliable modern flat-6. Oil separator system improved. Excellent longevity."
