here is some pictures of the kit compared to oem ford parts, only noticeable differences are that the metal on the aftermarket gaskets is slightly softer (which may be a good thing) and the gasket material is bonded very well, and the orings have the same density as oem and have a slight tackier feel to them which will not matter if properly lubed.
in my opinion overall this kit is very well constructed and should suit every need for oil cooler repair.
if anyone has any more questions or would like additional pics feel free to ask!
