That Combo here
Yes, the Precision SLIC shroud / scoop is narrower and taller that the KB Air Dam Scoop.
I didn't modify the Precision shroud / scoop, I modified (bent) the KB Air dam Scoop to fit under the SLIC Scoop. The KB piece meets the IC with a tongue, I slit this tongue vertically along the sides to make it more plyable and fitted it under the Precision shroud / scoop.
I still have to "seal" the setup - completely close up the KB piece along the length and sides, but I like the arrangement. The KB air dam scoop protects (runs under) the Precision shroud / scoop.
Pretty trick SLIC huh....it is quite a bit larger (more rows - 3" in and out) than my old CAS V-4.
