Let's see four screws and a clamp vs all the knuckle busting trying to get that thing around my Banks CAC tubes which ar about 3.5-4 inches in diameter, then very hard to discern as to the quality of the seal of the engine side of the housing after you wrestle that really compliant (NOT) housing back in place. IMHO a REALLY BIG PAIN IN THE ASS!
