I am totally confused at present with which part #'s I need.

My wife's car has 30k miles and I took it to the dealer.

They wanted $120 for Air Filter Cartridge ($55 labor/$65 parts).
They wanted $142 for Microfilter ($55 labor/ $77 parts).

Unless I am mistaken these are projects that I can easily do myself.

I contacted autohauzaz and there is some confusion on which parts I need.

For Air Filter Cartridge:
OEM Air Filter cartridge is #13717571355 (Mann) for $17. Please confirm part #.

For Cabin Filter / Micro Filter:
Autohauzaz indicated that I not only needed a cabin filter but also a microfilter. Did I misunderstand. They gave me the following part #'s and I don't know what to buy:

LAK630S (Mahle)
Cabin Air Filter

vs

CC-64319312318 Corteco-Micronair
Cabin Air Filter Set
$26.74

vs

64119237159 Mann
Cabin Air Filter Set

vs

64319237157 Micronair
Cabin Air Filter Set.

Which part # is correct?
Do I need a Cabin Air Filter set and a separate purchase for Microfilter set?
Some of the these show activated charcoal and some don't.
Do you suggest the charcoal activated? If so, which ones

I would appreciate your assistance in identifying the correct parts to order.

Thanks

Anthony

I usually buy the activated carbon filters, but it probably doesn't matter much.
