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

• The engine air filter protects the engine’s intake system and combustion process; the cabin air filter protects occupants from dust, pollen, and pollutants inside the vehicle.
• Both are vital: a clogged engine air filter can reduce power and efficiency, while a dirty cabin filter degrades HVAC performance and air quality.
• We use OEM-quality filters, document replacements, and explain warranty implications—repairs covered by warranty must be completed at a certified dealership like ours.
• To ensure both are inspected together, schedule service or view our service specials for bundled savings.

What are signs of a bad air filter?

• Reduced acceleration, decreased fuel economy, unusual engine noises, or black smoke can indicate a clogged engine air filter.
• For the cabin filter, signs include weak HVAC airflow, unpleasant odors, or increased dust in the cabin.
• Our factory-trained technicians diagnose issues quickly with OEM parts and clear explanations—helping you avoid more costly repairs later.
• We provide service financing and transparent estimates; to address concerns promptly, schedule appointment online.

• We recommend OEM or equivalent quality to maintain performance and warranty compliance; our parts team can explain options and costs.
