This inlet kit made a record 500whp on stock turbos!!
This is the ultimate high flow inlet kit for you N54 engine. It upgrades your stock inlet pipes which are around 1" ID at the smallest point and also flatten out like pancakes. The kit is made from steel wire reinforced high temp silicone and is full 2.5" ID (biggest on the market for intake pipes). With this kit you will be able to maximize the power from your stock or upgraded stock frame turbos.
These will not fit RHD (right hand drive)
You can see the proven bench flow testing done on these pipes vs the stock pipes in the chart attached. MMP high flow inlets are proven to flow almost 5x more than stock!!!
This kit is known to work in N54 LHD cars for 1 series and 3 series only
RHD cars not currently supported.

New N54 stock turbo world record dyno with MMP turbo intakes, 500whp, 540wtq!!!. Click on this link to go to thread for details
Dyno gains graph shown below for completely stock turbos. +45 max whp gain with only +3psi of boost and +56 whp gain at 6k rpm also maintains minimum 500 ft lbs from 3200rpm to 5250rpm! Gains throughout midrange and high rpm, a lot more area under the curve. This is bar none the best dyno horsepower produced with inlets on stock turbos! And it was done on an automatic with more drivetrain loss. Many have tried to break the record with "other" inlet system, and non have been able to.
Blue line is before MMP inlets, redline line is after inlets.
For upgraded stock frame turbos,these inlets have been shown to make 700 whp+
