What you may not realize is that keeping your engine’s air filter clean and maintained is just as important and can have a bigger day-to-day impact on your engine’s performance. To keep the best performance of your car, check the air filter regularly. PHILTOP EAF025 Engine Air Filter Protect Your Engine An air filter cleans the air going into your engine, filtering out dust, dirt, debris and particles. Without a clean air filter, those particles and debris would make their way into your engine, rub against metal parts and cause extra wear. Particles and debris as small as a grain of sand can cause damage. If those particles make their way into your engine’s pistons and cylinders, they can result in damage that’s far more expensive than an air filter. Reference Part NO#: CA4309 Compatible with Murano V6 (2003-2007, 2009-2015, 2017-2024, 2016 3.5L) Altima L4 (1993-2006) Altima V6 (2002-2018) Impreza H4 (1993-1999,2002-2007) Maxima L6 (1981-1983) Maxima V6 (1989-2018) FX35 V6 (2003-2008) QX60 V6 (2014-2019) G35 V6 (2003-2007) etc. Please confirm that the air filter matches your vehicle (Year+Make+Model+Engine) before purchasing! If you don't know if PHILTOP EAF025 fits your vehicle, you can read the User Manual (PDF) or confirm with us What are the effects of a bad car air filter？ Easily Clogged A clogged car filter will prevent air from passing through, reducing the engine's air intake, which in turn will cause a decrease in engine power and an increase in driving fuel consumption. Engine Damage Filters that are too dirty lead to poor filtration, causing impurities such as dirt, rocks, and other natural debris to enter the engine and wear out precision parts. Increased maintenance costs. Frequent Replacement The manufacturer’s recommended change interval is based on “normal” driving conditions. If you see a lot of black spots on your filter when you inspect it, it’s time to change it even if you haven’t reached the recommended mileage. Review: Nice fit - Nice fit on 2013 Acura MDX.
