Changing your engine air filter is a small task that can have a big impact on engine performance and longevity. For optimal engine health, it’s recommended that the engine air filter be replaced every 12 months or 12,000 miles. Most engine air filters are very easy to change – requiring few, or no tools and only a few minutes of your time. <br><br> ECOGARD XA6114 COMPATIBLE WITH: <br><br> Lexus CT200h 1.8L HYBRID 2011-2017<br> Lexus NX300h 2.5L HYBRID 2015-2021<br> Toyota Prius 1.8L HYBRID 2010-2015<br> Toyota Prius Plug-In 1.8L HYBRID 2012-2015<br> Toyota Prius V 1.8L HYBRID 2012-2017<br> Toyota RAV4 2.5L HYBRID 2016-2018<br>
