Both comprehensive and cost effective, Miller Performance offers
the 4" MAF conversion for M cars including their WAR Chip.
This package, developed by Miller Performance, is a very creative
and economical way to get more power and flexibility to these great
classic BMW engines. Engines that are both durable, and capable,
but have always been hindered by obsolete electronic hardware.
From Miller Performance:
Our new GenIII MAF is the best conversion ever for your classic
M. With our custom massive 4" MAF sensor, performance potential is
Unlike our Non M Car MAF conversions, the Gen III/ M-car only comes
in one size specifically tuned for the S14 or S38 engine. This low
restriction MAF will accommodate for any amount of flow your engine
will make with your future mods, like stroker engines or Turbos.
Being 4"- the Air box requires minor modification. This is

-The M3 MAF is a nice upgrade for the hungry 4 cylinder. It offers
a PEAK gain of 16 true HP at the wheels and a PEAK gain of 12 ft
lbs at the wheels! Even more exciting is the large torque gain
under the peak number, an impressive 17 ft lbs at 3400 RPM! Just
what the S14 needs.

-The M5 and M6 MAF’s had a few bugs during the Gen II life span.
While most people didn’t have any issues, there were a select few
that had drivability problems. We are always learning and Miller
Performance and striving to better our products and service. With
GEN III we have taken our knowledge and improved the drivability of
our MAF conversions for all cars. The Gen III/ M-Car MAF is by far
the best conversion out there for your M5 or M6. With our improved
design, the GEN III/M offers unprecedented drivability as well as
better performance than any of our previous MAF conversions.

>>>E30 M3 Silicone Intake Elbow, OPTIONAL
If your are increasing the diameter of your air metering device,
why not increase the entire intake track? For the E30 M3, the GEN
III/M MAF kit can come with an optional 4” intake elbow. This
increases the entire intake track to 4” opposed to the factory 3”
tube allowing you to move more volume of air for additional top end
power. Another benefit is less turbulence; the 4” silicone elbow is
smooth compared to the factory 3” corrugated elbow. Highly
recommended to make install onto your S14 as quick and clean as

can swap tunes, even while driving. This basically unlocks the
factory ECU and allows you to edit the parameters, something like
an aftermarket programmable unit
The process is simple; download instructions and a base map from
the Miller Performance "WAR Room" web site or included from VAC:
load to your USB WAR chip and your ready to drive!
If needed, fine tune your BMW for all the goodies you have
installed to or inside your engine. Along with the MAF conversion,
power and engine response is immediately improved considerably as
