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

• The engine air filter protects the engine by filtering intake air before combustion; the cabin air filter cleans air entering the passenger compartment for passenger comfort and HVAC performance.
• Both filters affect longevity and comfort: a clogged engine filter reduces power and efficiency; a dirty cabin filter reduces air quality and places strain on the HVAC blower.
• At Park Place Lexus Grapevine we replace both with OEM parts and provide clear documentation on service benefits and costs—view current offers on our service specials.
• We also offer service financing and warranty support; warranty-covered repairs must be performed at a certified dealership.

What are signs of a bad air filter?

• Reduced acceleration or sluggish throttle response, increased fuel consumption, unusual engine noises, or a check engine light could indicate a clogged engine air filter.
• Musty odors, reduced airflow from vents, or increased pollen/allergy symptoms inside the cabin suggest a failing cabin air filter.
• Our certified technicians at Park Place Lexus Grapevine will diagnose filter-related symptoms and recommend OEM replacements and maintenance plans when you schedule service.
• Choosing dealership service often saves you money over time due to correct diagnosis, proper installation, and warranty-backed parts and labor.
