Lexus RX 350/450h Carbon Buildup – Port Injection Advantage Malaysia
The RX 350's 2GR-FE uses port injection — minimal intake valve carbon buildup compared to direct-injection engines. The RX 450h's 2GR-FXE also uses port injection. This is a significant long-term maintenance advantage in Malaysia. Clean air intake throttle body every 40,000 km preventively to maintain optimal airflow. No walnut blasting required on any RX variant.
