ok so i'd seen the thing about the porsche? filter that fits.
why?
i've been running wix 51334, the EG33 filter.
the other one is wix 51287, which i recently put on.
it doesn't seem like there's much benefit, except like double the $.
in which case i'd rather change the filter twice.
i'm also running a flitermag,

on both engine and ext. trans (wix 51068) filters.
