Character
MA1
"718 flat-four. Controversial bore scoring debate (rare). Sounds worse than flat-6 but performs. Reliable so far."
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."
