Key Features
- A: On a technical standpoint, aluminum would be a little more subject the heat because it is metal, but, it is thin walled tubing, and would also dissipate the heat much faster as air is moving.
- We have been testing and running these for quite some time, and have out performed every other intake we have put it up against.
- The issue with a plastic intake, while it takes just as much time to heat up, it takes a considerable amount more time to dissipate that heat build up, also known as heat soak.
