That is one crazy price for the air filter.  It is no harder to change
than on most modern vehicles.   Most good real auto parts stores will
have them.  Chain stores which mostly do the high volume stuff (Kragen,
AutoZone, etc.) might not stock them yet.

I believe that the dealer was referring to air filter. Ask the dealer
to be sure.  If it's air filter, I had learned that with most cars, it
is soemthing you can do.

When I did it on my Nissan 2 years ago, even though I knew that I could
change it myself (or ask someone to do it for 10/20 bucks for labor to
put the filter),  I couldn't buy the air filter (it was hepa) from the
auto supply store and that only dealers would sell it.   So I did it at
the dealer for 80. Recently, I learned that you can just buy ANY filter
you desire, cut (and shape it if necessary) and put it yourself.  Some
suggested to get it from Walmart.

As far as I know, micron filtration and hepa filtration are top of the
filtration process. I lerned those when i was purcahsing a canister
vacuum cleaner 6 years ago.My kowledge may be out of date.

I will never let the dealer put an air filter for me again.

bull shyt on replacement on a 05? sounds fishy to me.
