Wix filters at car quest. No.

[Buzzie mcnugget]

I call my local auto parts store, car quest. 
You got wix filters in stock for a c6?
Sure.
Roll in to town,  here ya go, plops a car quest filter down. 
$3.50!
Um, that's not wix.
Yeah made by same folks. Hummel and Mann.
Research says that may have been true a few years back.

I took it because it was so cheap I will just keep it for a spare.

Ordered a proper wix xp filter.  Stunning difference, the wix is probably 2x as heavy.
I now have to find another local parts store, again.

Grrrr
