  • Experience an Obvious Difference: Whether you are noticing a delay in acceleration, less than average gas mileage or own a higher mileage vehicle, our Max Thrust engine air filters will provide a clear and cost effective upgrade over stock performance
  • Trap 2X Dirt vs. Standard Air Filters: Our unique Hex-D pleat design creates maximum holding capacity for trapping unwanted dirt and debris without compromising airflow like standard air filters thanks to multiple layers of progressively finer filter media that allows air to flow freely even when the filter is dirty
  • Increased Power and Mileage up to 15K Miles: Deficient airflow can cause your engine to work twice as hard to suck in the minimum amount of air it needs to perform regularly, resulting in poorer gas mileage and lower power efficiency; Max Thrust air filters are designed to give your engine a break by delivering as much clean air as it needs to perform optimally up to 15K miles
  • Do It Yourself: Replacement for Crosstrek (2016-17, does not fit Hybrid), Forester (2009-18, does not fit 2008 Forester), Impreza (2008-16, fits all trims), Legacy (2005-19), Outback (2005-19), Tribeca (2008-14), WRX (2012-19), WRX STI (2013-18, does not fit 2018 ‘Type RA’), make sure to enter your year, make and model above to check fitment; the engine air filter is an easy replacement that can save you money at the repair shop
  • Better Filter than Your Last One: We know it’s hard to choose from so many different brands carrying the same product; we make it easier for our customers to decide with a simple promise

    Did you know this about engine air filters?

     

  • An engine air filter will pay for itself with the money you save at the gas pump…a new engine air filter can increase your vehicle’s MPG by up to 10%.
  • There’s no better or cheaper investment you can make to extend the life of your vehicle than regularly replacing your engine air filter every 10-12K miles.

    When is the ‘right’ time to replace my engine air filter?

     

  • Warning/Engine Light Turns On: A light will appear on vehicles equipped with airflow sensors.
  • Noticeably Slower Acceleration: If your vehicle is slow to accelerate or responds poorly to pedal control this can mean your engine isn't receiving enough air to perform normally.
  • Reduced Fuel Economy: The less oxygen an engine consumes, the more fuel it will burn – causing fuel economy to go down.
  • 12K Miles or 1 Year: If you don’t remember the last time you replaced your engine air filter it’s time to change it out!
