Are these 3 the same.
I believe ac delco e and supertech are due to other video reviews and noticed Fram has the same filter number as St except a ph,tg, ect in front of the number
Example:
Pf46e ac delco
St3506 walmart
PH3506 Fram orange can
I know the 2 below are better quality.
TG3506 Fram tough gaurd
XG3506 Fram ultra
