To install or replace components, first disconnect the battery. For spark plugs, remove the ignition coils and use a spark plug socket. For air filters, unclip the housing and replace the filter. For oil changes, drain the oil via the pan, replace the filter, and refill with synthetic oil. Always refer to the service manual for torque specifications and proper procedures to avoid damage.

If the engine underperforms, check for error codes using an OBD-II scanner. Inspect the air intake system for blockages, ensure the turbochargers are functioning, and verify fuel pressure. Check for worn spark plugs or clogged fuel injectors. If issues persist, consult a certified technician to diagnose potential turbocharger or sensor failures.

To optimize performance, use premium fuel for better combustion. Regularly clean the throttle body and replace air filters. Consider upgrading to high-flow air intakes or performance exhaust systems. Ensure proper tire pressure and alignment for efficient power transfer. Avoid aggressive driving to reduce wear on the turbochargers and maintain engine health.
