Engine Oil Change:
Every 5,000-7,500 km (3,000-5,000 miles) or 6 months, whichever comes first. More frequent under severe driving conditions.
Air Filter Replacement:
Every 15,000-20,000 km (9,000-12,000 miles) or annually.
Spark Plug Replacement:
Typically every 40,000-60,000 km (25,000-37,000 miles) for platinum/iridium plugs, or sooner for standard plugs.
Timing Belt Replacement:
Every 80,000-100,000 km (50,000-60,000 miles) or 5-7 years. Critical due to interference engine design.
Transmission Fluid Change:
Every 40,000-60,000 km (25,000-37,000 miles)

Engine Wear:
Piston ring wear, valve stem seals, and turbocharger wear can occur with high mileage or aggressive use. The 4G63T is robust but requires diligent maintenance.
Ayc System:
AYC pump and hydraulic lines can be prone to leaks or failure over time. Fluid changes and system checks are important.
Clutch Wear:
Performance clutch upgrades are common, but OEM clutches can wear prematurely with aggressive driving.
Rust Corrosion:
As with many vehicles of this era, especially those used in harsh climates or rally events, rust and corrosion can be an issue in common areas like wheel arches, sills, and undercarriage.
Electrical Gremlins:
Older wiring harnesses and connections can sometimes develop issues leading to intermittent electrical problems.
