Boost Re-Calibration Jets

Although initially, it was very intimidating, once I got going it was a lot easier than I thought.
Installing the boost jets just required a bit of patience.
Basically I have to insert each of the two little boost re-calibration jets
into a small hose under each of the main air inlet tubes.

This is the left side of the engine where I'll be inserting one of the boost
re-calibration jets. It's under this big main air inlet tube that I will the
find smaller hose into which I'll be inserting the jets. There are two large
tubes, it's under the one towards the middle of the engine.

Ok... on the right side, is where I'll approach first. Notice under the main
air inlet tube, there is a small hose. On this small hose is a small metal
clip that clamps the hose onto a tube.

============
Press on this metal clip and move it 'up' the hose ( ie. towards the dash).
Then grab hold of the hose at or just below the metal clip (just so that the
metal clip doesn't slide off the hose and down into the engine bay), and pull.
If it's not too old... it should just 'pop' right out. Mine was very tight
and uncooperative, so I twisted it clockwise and counterclockwise, and wiggled
it up and down. This took all my patience (but that was because mine was
sooooo stuck).

Ok... back to the left side. On the left side, in order to get to the small
hose, I had to remove the big main air inlet tube. See in this picture the
missing air inlet tube? In a previous picture, I'll see that there are two
hose clamps at either end of the air inlet tube. I just have to loosen these
hose clamps and then remove the air inlet tube.

============
Look down to where the bottom part of the big air inlet tube was connected to.
If I look just below this now-open metal tube, I'll see that attached to it,
is a small hose. This is the small hose that I want to get at. Notice the
same metal clip as was seen on the other side. Using the same technique...
move the metal clip 'up' the small hose. Unplug/disconnect the small hose.

Back to the right side. I've got the small hose out. Finally!!! This is
what it looks like. I'm holding it up with a screwdriver for you to see! ;-)

============
Insert a jet into each of the small hoses. Insert with the 'pointy'
end going in first. It's shaped kind of like a little bullet head... the
nose goes in first. Insert it just enough so that
the back of the jet is flush with the small hose (ie. That it's all the way
into the hose... but no deeper). Now... just with my pinky finger, push it
just a little bit further in. Now reconnect these small hoses ... and the
piece where I'll be reconnecting these small hoses, will push the jets further
down the hose. It won't push it so far down that if you ever have to
remove it, it'll be too much of a pain. Re-connect everything that I had
disconnected, and I'm done.
A small tip if you ever have to remove the jets. If you have the little
hose removed, then you simply have to squeeze the hose just below where
the jet is placed... and slowly but firmly squeeze the jet out, like you
would toothpaste. If you find that this does not move it out fast
enough for you, you can wrap a rag around the hose just below the jet, and
then squeeze the hose with a pair of pliers.... at the same time... holding
the open end of the hose in your hand... you can wobble it back and
forth to help the jet move back up out of the hose. Remember... you do
NOT want to drop these little jets back into your car somewhere. They aren't
the biggest/easiest thing to find!! ;-).
Ta-Dah!!!
