Premium Guard automotive air filters are tested to the highest standards, ensuring optimal performance from both the air filter and your vehicle's engine. Our stringent testing practices address three factors that affect overall filter performance: efficiency, restriction of airflow, and dust-holding capacity. Delivering high efficiency and high capacity, our engine air filters maximize airflow through the filter into the engine, resulting in cleaner air and longer air filter life. Enjoy maximum engine protection and operation with Premium Guard air filters.

Efficiency describes the volume of dirt and pollutants that an air filter prevents from entering an engine. High-efficiency Premium Guard engine air filters trap up to 99 percent* of dirt/pollutants over the life of a filter.

*Tested per ISO-5011

Restriction of airflow measures the air flow that passes through the car filter into the engine. Our automotive air filters are designed to maximize the flow of clean air into the vehicle's engine, enhancing its power and performance.

Dust-holding capacity refers to the quantity (weight) of airborne pollutants captured throughout the life of the auto air filter. All Premium Guard air filters feature high dust-holding capacity for exceptional longevity and performance.

Common Indicators It’s Time to Replace Your Engine Air Filter

  1. Engine Light Comes On: Many cars are equipped with an airflow sensor that sets off the check engine light.
  2. Visual Inspection: Premium Guard automotive air filters are white so you can see if they're dirty. Check the outside and inner layers of the filter paper for dust and debris.
  3. Reduced Fuel Economy: When engines get less oxygen, they consume more fuel. If you notice fuel economy going down, you may need to replace the air filter.
  4. Engine Misfiring: Restricted air supply results in unburnt fuel exiting the engine as soot residue. Soot accumulates on the spark plugs, which can cause the engine to misfire.
  5. Reduced Horsepower: Replacing the air filter can improve acceleration or horsepower. If your car doesn’t respond well or jerks when you step on the accelerator, the engine may not be receiving the air it needs to perform.
  6. Black Sooty Smoke or Flames: Poor air supply can result in fuel not burning completely during the combustion cycle. Unburnt fuel exits the car through the exhaust pipe, possibly resulting in smoke or flames.

*Certain conditions can impact the life of the air filter. Possible causes of more frequent replacement include:

  • Driving conditions
  • Dusty roads
  • Humid climates
  • Congested roads and heavy-traffic areas

Subaru did not make it easy to install this filter. The new filter seems like the material for the filter might be thinner than the OEM version. I think I will change this filter more frequently due to this. Next tie I will probably buy one of the more expensive filters because the filter material did seem thinner. The filter did fit and will do the job.

Perfect fit, good price, speedy delivery. Dealership charges $60 to change the filer....a 5 minute job, if you take your time.

I have a 2020 Subaru Crosstrek Limited, and this air filter fit perfect. The whole process took me about 10 minutes. I watched a great YouTube video by Patrick Kasalig and followed the step-by-step process. Great way to save money and keep your car running at its best.

En México se manejaron con este vehículo como SubaruXV, Pero si ustedes buscan las mismas refacciones, solamente pongan Subaru CrossTrek y el año, es el mismo vehículo, sólo que en Estados Unidos se le conoce con el nombre que les acabo de mencionar. La refaccion es identica a la de agencia.
