NACA duct

[brian257]

I am searching for a NACA duct for a non-RV for cabin air. Looking at Spruce the ones they sell have horrible reviews about being made with cheap flimsy clear plastic. Looking at race car web sites seems they sell big ducts that won't fit and small ducts for cooling brakes that are too small.

Checked the Vans web site and they sell a VENT SV-1 which may be jsut what I am looking for, but I don't see dimensions and the price seems unbeliveably low at $6.25 when the others I look at cost much more.

Can anyone confirm roughly the size of this vent and is this the only NACA duct that Vans sells?

Same part number as the two that I installed on my fuse.
Proseal and neodymium magnets.

installed two in my RV4 cheek cowls. They are solid, stable and glued to glass cheek cows with epoxy.

Howdy Brian. The SV-1 is 8.5" long and 4" wide. The duct connection point is 2" OD. I believe these are the only ones Vans sells.
