2G MAS with 1G Air Filter
Call me cheap, bored, whatever. I had 2 things to start with. One: A second generation MAS (Bigger air intake, see VFAQS) and Two: A Non-Turbo MAS which I will never use. I realized one of my many 1G K&N filters fit the non-turbo air box so I decided to use it and save by not buying a 2G Filtercharger. I had some time anyway. Also, I do not own a welder, yet.

I took a piece of cardboard and traced the 2G sensor
to make a template.

Placed it on the Non-Turbo Air box plate and scribed
a line.

I bought some heavy duty cutting discs for the dremel
and cut around the lines. Oh Yeah, I used eye protection after
a piece of metal shot into my eye. Also, my gun range ear protection
made the grinding noise bearable (Dental Flashbacks).

After the cuts, the only thing connected and in the
way is the raised hole where the turbo intake pipe connects (dotted
lines). I cut a couple of inches and its off. BTW, look at the
hole there and the 2G mas scribed line to see the intake size difference.
Wow!

Here I smooth the rough edges (after bleeding a bit)
with a grinder.

I placed the gasket back from whence it came.

I cut a piece from the left over metal and placed
it on the gasket, overlapping where the old plug was. I also added RTV
sealant before placing it on to make sure it seals. The dotted line
shows the cut piece of metal for clarity.

Place the bracket over the piece of metal and tighten
it down.On the back side, I piled on RTV just to be safe (see
next pic). Now it is sealed nicely.

I removed from the old mas where the screws held it
together to the plate. I put 4 screws from the old one back
through the holes and tightened them to prevent leaks there. I also
added RTV to the screws and the round threaded nut like thingies to
seal. They will not get in the way of the new MAS.

I put the 2G MAS on to mark where to drill the four
holes for the bolts to hold it together. Then Drilled them out.

Here is the inside shot (I need to get the four
bolts to hold it together). I will add RTV where the MAS meets the
plate when I bolt it on.

Other side. Finished. Now I simply snap in the 1G
filter. Later, I will rewire the 2G harness to work with the 1G plug
(See The VFAQS). I am going
to wait until the engine is rebuilt for the AWD. I will use this when
I get the 550 or greater injectors in. With a SAFC of course.
