Re: Cabin air filter DIY
Cabin air filters are one of those items that come and go.
For example, on my current program (Chevy Volt and Opel Ampera) we do not have them released for domestic use but do have them released for export.
The downside for cabin air filters is (a) initial cost (b) a reduction in air flow and (c) proliferation of HVAC units in the assembly plant. If the program team is sensitive to any one of those areas, or warranty cost (as indicated in the first few posts of this thread) then the filter is an easy victim of a cost reduction initiative.
