Not moving off the cold mark doesn't sound right to me...even for a cold air intake. IIRC, that gauge gets its reading from the coolant. And it takes longer for the coolant in the block to warm up vs a piston or egt probe. That gauge is not a substitue for a pyro. That gauge should get in the normal operating range, at least that is when my truck starts to shift better and run smoother. I don't consider the 6637 intake as a CAI. It is still completely exposed to the heat of the engine bay. Some people have fabricated an aluminum box to go around it and seal agiainst the hood. But it is still better than stock and cheaper than other CAI
