Bmw S55 high flow turbo inlets

High-Flow Turbo Inlets for the S55 engine, as found in the F87 M2 Competition/CS, F80 M3 and F82/F83 M4.
The original plastic turbo inlets are restrictive, especially when running hybrid turbochargers with enlarged inlets. This restriction not only causes reduced airflow, but can cause increased intake air temperatures. Turbo inlets feature a hugely increased internal diameter for a smoother, larger intake flow to maximise inlet performance
S55 original  pipe is too small
If you increase the boost value or upgrade the turbocharger
it improves the last restriction of air flow into the turbo. 
This turbo intake pipe will improve turbo response, increase air flow and less turbo lag.
