Profab 3" Boost Pipe (Cold Side) 04.5-10 GM 6.6L Duramax

This 3″ boost tube is for use ONLY with our LLY – LBZ – LMM shorty bridge.

It runs over the alternator and in front of the motor making it ideal for use with twins and big singles.

It gives a significant flow increase and comes powder coated black & includes the upper hose and clamps. The LLY install requires some tweaking on the coolant and trans lines in front of the motor. The LLY tube comes with the longer 90 degree lower boot and clamps.

NEW Product!! We now have these for the LBZ – LMM that go behind and beside the alternator in a more stock location. ( Will Not work with the LLY) Make that selection above.
