Has anyone used the sinister oil cooler in their 6.0's are they good bad or what? I did one a while back for a guy and used one and the part looked of good quality but the box it came in kinda had that tell tale sign of a box from China you know the ones. I didn't have any trouble with it but made me nervouse when i was suspicious of the package. do any of you use them or do you all stay away from them?
