If you've ever seen the inlet pipe to the throttle body to the Toyota 2.4L T24A-FTS, you'd see it is a literal joke for airflow into the engine. Without knowing the OEMs intent for sure, we see it being a manufacturing process/material decision coupled with installation. Being made from injection molded nylon, the molding process determined much of the exiting shape. We could be wrong but that is our best guess here.
Seeing this pipe as a problem when much of the intake tract is over 2.5in in diameter, the OEM pipe crimping down to 1.5in ID at its worst point seems like it would cause a problem.
After 3D scanning the OEM pipe, we got to work on making it as large as possible while still making it as easy to install as possible. We managed to create what you see here, which absolutely swallows the OEM pipe up.


Here is a prototype next to the OEM pipe in real life!


The pipe itself will be cast aluminum, welded to the throttle body flange CNC machined from aluminum as well. This is a rendering of what the final part will look like.

Dyno testing and more info coming ASAP as soon as we get this tested!
