LBZ/LMM Max Flow Bridge & Cold-side tube combo

*Cold-side tubing routes behind the alternator similar to factory routing*

Increase performance and flow with our upgraded 3" Max Flow Bridge. Our bridges are CNC machined, for a perfect fit and great air flow. Our 2 piece design allows for an easier install, compared to other bridges on the market. For the ultimate flow and performance gains the max flow bridge is for you!

With the addition of the upgraded cold side tube in combination with the max flow bridge, this is a very high flowing, power increasing combination.

We have done dyno testing to prove horsepower gains with this combination.
