Are the caps interchangeable? Or is it more than just the cap?GM really dropped the ball on this one. The oil filter housing should have been designed so that it won’t accept the other filter design. I’m mad that GM did this and I don’t even own one of these engines!
To avoid this headache in the future I would swap out the UFI oil filter housing and install the Hengst. But that’s just me. It sounds like there are more Hengst designs in operation and the likelihood of getting the correct filter installed is higher.
