Inspect every 15,000 miles (24,000 km), replace as needed. Often recommended around 30,000 miles (48,000 km).

Cabin Air Filter:

Inspect every 15,000 miles (24,000 km), replace as needed. Often recommended around 20,000 miles (32,000 km).

Spark Plugs:

Replace at 75,000 miles (120,000 km) for iridium-tipped spark plugs.

Automatic Transmission Fluid:

Mazda typically lists 'lifetime' fluid, but independent experts recommend replacement every 60,000 - 100,000 miles (96,000 - 160,000 km) for longevity, especially under severe use. Consult manual for specific recommendations.

Coolant:
