I bought this AC Delco Cabin Air Filter CF1179CF (GM# 19338051) but my 2010 Traverse LTZ doesn't need it.
I was about to take the filter to Goodwill but I'd rather get it to somebody who could use it.
I estimated the price at $15 because I'm not trying to make any money on the filter just have the shipping paid.
If you have a better shipping rate you could send me a shipping label and I'll send you the filter at no additional charge.
