3.5" Pro-Tube

The 3.5" Pro-Tube is a universal mass air meter for "Blow Through" applications. It simply becomes a part of the duct work between the supercharger (or turbocharger) and the throttle body. The 3.5" Pro-Tube features welded construction (no cheesy rivets!). The ends are bead rolled for a positive seal that grips the hoses, preventing them from blowing off even at very high boost levels. . 

These meters will not become a corroded eye sore like the competition's products. They are clear anodized for good looks for many years to come. 

As with all Pro-M meters, the Pro-Tube is held to a tolerance of 2 percent. It is suitable for applications making as much as 2000 flywheel HP. 

Your new Pro-M Mass Air Meter is shipped to you with a Flow Data Sheet that was generated by your mass air meter on one of our flow benches. This flow sheet verifies that your new Pro-M Mass Air Meter was not only properly calibrated, but also functioning properly just minutes before it was boxed and shipped from our facility. This virtually eliminates the possibility of receiving a defective part. No one else does this!

Every Pro-M mass air meter plugs into your vehicle's harness connector without modification. 

Tuning is required when using a meter in a blow through application.
