To install or replace components, first, disconnect the battery. For spark plugs, remove the ignition coils and use a spark plug socket. For the air filter, open the airbox and replace the filter. For oil changes, drain the oil via the drain plug, replace the oil filter, and refill with the recommended oil. Always refer to the service manual for torque specifications and detailed instructions.

If the engine underperforms, check for error codes using an OBD-II scanner. Inspect the air filter, spark plugs, and fuel system for issues. Ensure the oil level and quality are adequate. If the problem persists, inspect the ignition coils, fuel injectors, and exhaust system. For persistent issues, consult a certified Lexus technician for a thorough diagnostic.

To optimize performance, use high-quality synthetic oil and premium fuel. Regularly clean or replace the air filter and ensure the throttle body is free of carbon buildup. Upgrade to high-performance spark plugs and consider a performance exhaust system. Regularly monitor tire pressure and alignment to reduce engine strain. For advanced tuning, consult a professional.
