View Full Version : What direction does the sample tube go in the C&L MAF?

Does the slanted sinde go into the flow, or does the flat side go into the flow.

The one I have had a 42lb sample tube on it, and I replaced the sample tube with the red one (for 50kbers) in the same orientation, but I am unsure if it was in the proper orientation when I got it???

I believe I have the flat side pointing towards the front, into the airstream...

I think the flat side with the color marking points to to tb downstream.

I just went through this at the Dayton Meet Dyno, so I now know that the angle side gos toward the filter.

Think about how the air would be less restricted, is how I was told.

And like already stated have the flat colored side towards the throttlebody.
