What parts are worth getting from Ford?

[coronan]

Hello,

 

I'm taking over the maintenance on my GF's Edge with 100k mi.

 

I try to put thought into parts / brands I buy. I don't like going to the big box stores because they tend to push crap with a lifetime

warranty.

 

I also know that the Dealership isn't called the "Stealership" for nothing. Generic things get rebadged.

 

What parts are worth getting from the dealer?

 

Any online parts resources for OEM.

 

Any recommended part numbers that have proved themselves?

 

 

 

Thanks!
