This shows both intakes installed with the engine covers. From here you can see the manufacturing differences. Vectors cut and weld method and IATSRT8s mandrel bent system. Below you can see the differences in the 90 elbow

NOTE: There is a New Version of the Vector intake that supersedes the one shown here. Click here for more details.

These photos show the 90 degree elbow that connects the intake to the 90mm throttlebody. The top is IEATSRT8's silicone coupler and the lower one is Vector's hi-temp rubber coupler.
