The stock inlet is narrow and restrictive.  Plus, I like the look of the Forge/Samco one.  It isn't cheap but I think it's worth it.   In conjunction with my CAI the turbo has no trouble spooling up in record time now that it can breathe properly.

Now, one thing is this reduced that WHOOSH sound I was getting when I shifted after installing my CAI.  That's because of a lot of reasons, mostly the angle of the new Samco pipe though.  You still get the sound but it isn't as loud.  However your turbo sounds like a damned monster under your hood because of the big tube that is feeding it air now.  Woot woot!

• Forge Inlet - This is sooo much better than the stock piece of junk, and unlike the Neuspeed one it replaces the whole line and not just the metal inlet pipe on the end where it connects to the turbo.
• Lots of hose clamps ranging from 0.5 inches to 3.5 inches.

• Metric Torx bits
• Screwdrivers
• Pliars
• Beer

Put the car on ramps or jackstands.  You need to get under it for some parts of this install.

Take all the hoses off the top of the stock tube that goes from the MAF to the metal turbo inlet.  Most are those annoying VW clips.  I like to get them off by sticking a screwdriver in the clamped area and turning it to pry them apart.  Then I open them up with pliars.

Now get under the car and look for the metal inlet.  There is a bolt holding it to the turbo.  It is a SIZE 5 METRIC ALLEN KEY.  Bad picture but you get the idea.  Also note the tube on the inlet, you gotta remove this too.  I pried it off without really doing anything to the clamp since getting one of those clamps off under the car would be hell.  Then I pulled the tube up after everything was off and removed the clamp.

Now patiently wiggle the tube around until you can pull it out.  I didn't have to remove anything else to do this.  This is where the beer comes into play, it may take a few minutes to get it free.  This is a comparison pic of the stock unit out of the car next to the Samco.

Now the suck part:  getting the Samco back on the turbo.  Put that hose you took off the metal inlet on now and tighten a hose clamp around it.  This is eaiser than doing it from under the car.

Push that inlet down there now!  All I can say is that I'm glad I have long arms, you really gotta squeeze it down in there and then reach under the CAI to push it into the turbo.  Again, patience will pay off.  You have to make sure the inlet is all the way on the turbo.  ***Don't forget to put a hose clamp on the end first and line it up so that the screw points down to the ground so you can tighten it!****  Go back under the car and verify that it's on correctly.  Once you get it in place tighten the hose clamp until you can't anymore, VERY TIGHT is key here.

Now attach the MAF block to the other end of the inlet and tighten that hose clamp.  You get to reconnect all 5 tubes and parts now, yah!  The strange circle piece broke me like a twig getting hit by a tractor trailer.  The Samco hose was to damn small and it took me way longer than it should have to get it in.  But, after a tiny bit of Mobile 1 synth lube it went in and I tightened the hose clamp on.  Put everything else on too.  Wheee....

And....

It's a good idea to make sure you put everything back on right, or your engine will probably do something bad like die.  ;)

When I first test drove this after installing it the car was pushing less boost by about 1 PSI, but that went away after my next ride around the block at turbo screaming way to high speeds. 

This is a great mod, enjoy!
