@Grsemky - The damaged fins on the backside of the radiator is quite interesting? 🤔

@M-Sport fan - The FL400S was used on the 1.9L SOHC 88HP Ford Escort engine back in the early 1990s. They later downsized the FL400S. This was taken sometime between 2008 and 2010...

Caption: Left - Original, larger FL-400S Motorcraft oil filter. Right - New smaller FL-400S Oil Filter. Note, the 'designed and engineered by' clause has been removed. Part number remains identical.
The better (Ultra/Endurance) Fram filters are closer to that older, larger FL400S.

That's exactly what I did. But ever since I installed the Mountune radiator the clearance doesn't allow it to slip past with the engine side of the filter facing up. I had to face engine side up as usual and then pull really hard to slip it past the rubber hoses. When installing the new filter it got scratched from the metal hose clamp.
It’s a tight fit for sure with the Mountune rad and FL400s but I always manage to slip it out with no trouble. I remember I used to run an even bigger Wix (56569?) filter with the stock rad and I determined I couldn’t do that with the thicker Mountune rad
