I recently changed the air cleaner on my Mazda3. The owner's manual told me to remove the battery cover and duct, unfasted the clamps and lift off the air filter cover and remove the filter. Well... ... ... not quite so simple. The air filter cover didn't want to lift up and out of the way. I was able to change the filter, but was not able to clean out the air filter cover and housing like I would have liked. So I don't waste a lot of time re-inventing the wheel so to speak, what is the simplist way to remove the air cleaner components up and out of the way so I can thoroughly clean the filter cover and housing and any other related parts?
