Engine Air Filter vs Cabin Air Filter

Understanding the difference between the engine air filter and the cabin air filter helps drivers protect both performance and comfort in a 2018 Ford Focus ST. The engine air filter guards internal components and turbo efficiency by filtering intake air; a clogged engine filter can reduce power, worsen fuel economy, and stress the turbocharger.

Both filters are essential: one for vehicle longevity and performance, the other for occupant health and comfort. At Larry H. Miller Super Ford Salt Lake City, we inspect both during service visits, use OEM parts, and clearly explain findings and warranty implications.
