Spark Plugs:
Inspect every 30,000 miles (48,000 km); replace as needed (typically iridium plugs have longer life).

Engine Reliability:
Head gasket failure is a known issue if the engine is overheated or consistently driven hard without proper maintenance. MIVEC system can be sensitive to oil quality.
Ayc System:
AYC pump and accumulators can fail over time, leading to system warnings or malfunctions. Fluid contamination can also cause issues.
Rust And Corrosion:
As with many cars of this era, particularly those driven in climates with salt, rust can be a concern on body panels, sills, and subframes.
Turbocharger:
Turbo seals can wear, leading to oil consumption or blue smoke on startup. Regular oil changes are critical for turbo longevity.
Suspension Bushings:
Rubber suspension bushings degrade over time, affecting handling and ride quality. Polyurethane replacements are common upgrades.
Heritage:
Mitsubishi has a strong heritage in motorsport, particularly in rallying, with the Lancer Evolution lineage being a direct result of its WRC program.
