Mishimoto MMCLAMP-425T Stainless Steel Constant Tension T-Bolt Clamp, 4.09"–4.41" (104 mm–112 mm)

Clamp works good at the moment but it's not what's on the picture.On picture we have a constant tension type clamp due to string which is what you want at high pressure intake systems. But what came is normal type clamp. One pays higher price expecting a better product. There's plenty of other good clamps without constant tension spring for lower price.
