With the x5m's it seems like besides a replacement filter NOBODY makes a completely replacement intake kit for this vehicle.. something with tubing, heat shield, bigger size filter etc..

While inspecting the x5ms engine bay and where the stock filters are and where the intake manifolds are.. it seems like an easy custom project of making some tubing to go from the engine intake manifolds to the front grilles.. something like this

My question is; is the hassle worth it? Will the turbo/engine improve a lot due to a bigger intake with cooler air.. ? Or is just a waste of time to mess with a car like this?
That intake system looks much like the MSR system for the F10 M5, which from every review, makes big gains and also allows you to hear the turbo and BOV better...and it's only like $2500

I wrote MSR and they don't produce anything for the X5M and their intake couldn't be adapted anyways since we've got more subframing in the way to prevent using it.

Something that could go straight from the grills to the turbos would be optimal for a complete straight shot, almost like the stock system is now, but we've got a much tighter space to fit a cone filter between the grill and radiator compared to the F10 M5. I found this on my Google searches, but looks like a rats nest mess that'd be completely prone to heat soak - VA-Motorsport Engineering - official KNAF rollcage manufacturer
