How often should I change the engine air filter on my 2022 Lexus RX 450h?

• Replacement intervals depend on driving conditions, but most drivers benefit from inspection at every oil change and replacement roughly every 15,000–30,000 miles for normal use.
• If you drive in dusty or high-pollen areas, interval shortens—our technicians will recommend the optimal schedule to protect engine efficiency and hybrid components.
• All warranty-covered repairs must be performed at a certified dealership to maintain coverage; our service advisors will document intervals and warranty details clearly.

What is the difference between an engine air filter and a cabin air filter?
