This manifold is off a 93 Civic CX/VX, notice it has a "L" on the #4 runner.

The HF, Std, & Civic CX/VX from top to bottom. As you can see there really is hardly any difference in the manifolds. The STD has the largest runners, and the HF/CX manifolds are nearly identical.

No markings on the HF manifold.
