March 26, 2017 - Part 9120
Fits perfect, as expected. A must when swapping to a Boss 302 manifold for proper fiitment with an Airaid intake.

This coupler works perfect for the Boss 302 manifold. I highly recommend it, fits perfect with no modification like the install video recommends for the normal coupler.
