I bet AC Delco makes one, as this was a Ford product... just need someone with access to figure out which filter.
Engine air filter AF7921
4.4L Engine Oil PH2009
No cabin air to be found.
I guess in the end, the article is somewhat informative, but none of the winners make all the filters for this vehicle. I spent an hour attempting to find someone that actually stocks the Delco part number, nobody. The Baldwin and AFE do not make them for the LR3 at all, that leaves whats left, with a fairly close tie. All in all, the Wix might be the best average and it is available.
Wix Engine Air 49112
Wix Cabin Air 49369
Mann Engine Air C 31 196
Mann Cabin Air CUK 2747
Taking the comments to heart. I did a baseline 99 miles on a clean and serviced K&N and have swapped it out with a new Wix filter and will be comparing at 99 miles the MPG and general performance if anything is noticeable.
