ECB 3D Printing has made Hood Scoops for the RC4WD K10 and Blazer. These can be glued or double sided tape on the hood and can be used as is or with a little body work it can be blended onto the hood as our example. 
 
We printed this in a detail setting to minimize layer height so if you plan to smooth the arch it will require less work than if it was printed with speed and thicker layer heights. 
 
The Cowl Induction Hood Scoop became popular on the 1969 Camaro Z-28 and the aftermarket has been making them for many cars and trucks since. Our Cowl Induction Scoop was designed to look like standard 1:1 hood scoops that you would find on street trucks. It has a nice front radius with the central hood bump just like the RC4WD hood does and it also has draft angles on the sides just like stamped steel truck hoods would have.
 
The L-88 Hood Scoop started out on the 1967 Corvette and has since been added to other vehicle hoods by aftermarket companies. 
 
Included is one Cowl Induction Scoop or one L-88 Scoop in black. Hood is not included. 
 
This may fit other hoods but we have not tested anything else at this point.
