Your engine's air filter keeps dirt and debris out of your fuel system and engine. A clean filter helps your engine run efficiently and improves fuel economy. Most vehicles need an air filter replacement every 12,000 to 15,000 miles, though driving in dusty conditions may require more frequent changes.

Signs your air filter needs replacing: reduced fuel economy, engine hesitation, or a clogged appearance. Bob Allen's Service team can inspect your air filter during routine maintenance and replace it with a genuine OEM filter when needed. Stop by or call **(877) 331-4442** to check your air filter and keep your engine breathing clean.
