Checking Air Filters

[John105]

No joke! Once I found the air cleaner housing of my mother's car roughly one-third full of dog food---fortunately all on the dirty side of the filter.

My parents too, on a Camry. It got to the point where the car would stall.

If I showed you my K&N filter, you would faint.

Definitely, if you show us the receipt of what it cost you

I used to follow this advice, until I discovered a mouse nest in the airbox of one of my vehicles. On another vehicle, I discovered a leaky seal that was allowing dust past the filter. A restriction gauge would have helped detect the mouse nest, but there's no real way to check for a sealing issue without inspecting the clean side of the airbox.

Was the mouse next on the clean side of the airbox? If yes, how did it get there? If the nest was on the dirty side, again, this could be discovered and cleaned, without removing the filter and disturbing the seal.

It was on the dirty side. Luckily the air filters for my motorcycle are designed with a metal screen on the clean side of the filter to prevent mice from chewing though it and getting sucked into the engine and decapitated by the intake valves.

Mouse nest/acorns

Acorns in air filter

Have also had mice/chipmunks make a nest under the engine cover on my Avalon.
They scraped off the foam from the underside of the cover and made a nest.
Found nest before they started chewing on the wires.

Those are emergency rations incase you break down way out in the woods

Whenever I check my air filter I end up accidentally touching the clean side of the filter and making it dirty. Like one or two fingerprints. Would you replace the filter after this happened?

I never check my air filter. I change it once per year, whether , it needs it or not.

I change mine every 2nd year, even if it still looks fine, cabin air filters to.

Its from the dirt in the engine bay.

You have to lift up the air box and pull out the filter

Common sense tells me to wash my hands AFTER opening up the air box.

I had schrews install a prefilter on my 90 Wrangler. It did not enhance performance.
