One of the reasons our airbox is not compatible with other hoses is because we increased the outlet size on both the airbox and the turbo inlet pipes together. We did this because that is where the largest restriction is in the system. If we made either part compatible with the stock components, we’d have to reduce the size, which wouldn’t address the restriction we were trying to minimize.

I personally enjoy making each part separately just so users can mod over time, or upgrade only the parts most critical to the build, but sometimes, like is the case here, there isn’t a choice without sacrificing performance.
