Your car also may need some work. Flash some light behind your engine air filter to see if it needs to be replaced. How much light will require a replacement?

Answer 50% or more

If you think your engine's air filter needs to be replaced, remove it from the air filter box and hold a shop light behind it. If 50% or more light shines through, it's time to install a new one.
