Stick with OEM then or is there a reccomended alternative?They do absolutely nothing for these engines.
Pipercross will most definately shorten the life of the maf's.
When are you likely to be launching your intake system?Stick with the OEM.
When we first purchased our M5 and dyno tested it the first thing we did was to put some BMC filters in. It's rude not to test given we have all the time in the world for these things.
Not even 1 HP. No difference anywhere over clean stock filters.
Buy a proper intake system like Dinan or what we will be releasing in the near future.
