According to the check list in my owner's manual, both the primary and secondary air filters are to be replaced at one year or sooner if you have to clean the primary a lot. So I went by the dealer's to pick up one of each, and the gal who does the parts says "practically no one changes the secondary" and there have been OTT threads discussing the pro's and cons of not changing the secondary. So I didn't buy the secondary this time.
However I was interested to read in the WSM that it said Do not touch the secondary element except in cases where replacement is required. Well it is not possible to get the primary off and on again without the primary touching the sides of the secondary due to the hood being in the way of a straight on access.. Do you think there is something about the secondary that would lead to it not functioning properly if the sides have been touched? It is blue instead of white like the primary.
An example of something like that is projector bulbs and microscope light bulbs that burn out faster and don't give an even illumination of you get fingerprints on them.
Or is this another case where something got lost in the translation?
