Anyway, I took some exact measurements with a micrometer.
Spectre MAF tube
(little larger than I thought)
Here's a pic of the 3" Spectre MAF tube and two 3" tubes on each side.
i like your intake setup, what is that red tube at the end of intake is that your filter are you using a low profile filter to fit in the fender?
