Air Filters

AIR FILTERS - FREQUENTLY ASKED QUESTIONS

• What does an engine air filter do?

  Your engine air filter keeps dirt, dust, and debris from entering the engine. Clean air helps your engine perform better, last longer, and to be more fuel efficient.

• How often should I replace my engine air filter?

  Most manufacturers recommend changing it every 12,000 to 15,000 miles, but it’s best to check your owner’s manual. If you drive on dusty roads or in heavy traffic, you may need to replace it more often.

• What are the signs that my air filter needs to be replaced?

  Signs that an air filter should be replaced include reduced acceleration, decreased fuel efficiency, a rough idle, or the presence of dirt and debris on the filter itself. Regular inspection can help identify the need for replacement.

• Can a dirty air filter really affect performance?

  Yes! A clogged filter restricts airflow to your engine, reducing power and fuel efficiency. Replacing it helps your engine “breathe” easier and run smoothly.

• How does a clean air filter help fuel economy?

  A clean filter allows the engine to get the right mix of air and fuel. That balance improves combustion and helps you get the most out of every gallon.

• What materials are air filters made from?

  Most air filters use pleated paper or synthetic fibers. This is often reinforced with a plastic or metal mesh for strength and durability.

• Can I clean and reuse my air filter?

  Most air filters are disposable and should be replaced. However, some aftermarket performance filters are reusable and can be washed and re-oiled.

• What should I watch for when installing a new air filter?

  Make sure it’s seated properly in the housing, the air box is closed tightly, and there’s no debris inside before installing the new filter.

• Does driving in dusty or off-road conditions affect how often I replace my air filter?

  Definitely. Dusty or off-road environments can clog filters faster, so check and replace them more frequently to protect your engine.

• How do I know which air filter fits my car or truck?

  You can find the right fit by checking your owner’s manual, using an online parts lookup tool, or asking a parts specialist. Having your VIN handy also helps ensure accuracy.

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

  An engine air filter protects your vehicle’s engine from contaminants. A cabin air filter keeps the air inside your vehicle clean for you and your passengers.

• Should I use a performance air filter instead of a standard one?

  High performance filters use a different type of media (i.e., paper) and are sometimes reinforced differently than conventional air filters. The media used is more porous. This is what increases air flow to the engine resulting in higher horsepower. Normally, a high-performance filter will last longer because it filters out less harmful elements. The best choice depends on your driving style and preferences.

• Do turbocharged engines need special air filters?

  Turbo engines can benefit from high-flow filters designed to handle greater air volume while maintaining strong filtration performance.

• Can a clogged air filter cause a check engine light?

  Yes. A severely restricted filter can affect your vehicle’s air sensors, potentially triggering a check engine warning light.

• Are newer synthetic or advanced filters worth it?

  Some drivers find them worthwhile. They provide excellent airflow, longer service life, and improved dust protection compared to traditional paper filters.
