Re: Oil Filter Study
The Hastings has a spring and nitrile ADBV. The filter pleats were not very evenly spaced.
Baldwin Filters manufacturers Hastings filters. One common feature of both of these filters is the identical canister core. Instead of round holes it has formed perforations. The start and end of the filter are held together with a metal band crimped on the inside of the filter.

This filter appears to have excellent filtration capability and lower than average flow.
The Fram TG filter shares the smallest intake hole area as its brother, the Fram EG, at 0.227 sq/in. This is the only filter outside of the WIX and PureOne filters that has the silicon ADBV. Silicon is supposed to be less prone to harden after being subject to long exposure to hot oil.
The minor differences between this filter and the lower priced Fram EG is the silicon ADBV, 10 more pleats, 90 sq/in more filter area, and a slightly thicker filter material.
The other similar design the TG has with the EG is that it has cardboard or paper endcaps with an open hole on the bottom. The leaf spring plugs this hole.
Here is the leaf spring shown with the circular form to plug the bottom endcap hole.
Here is the leaf spring installed.
Here is the inside canister showing the hole size and pattern.
