Owners of high-boost Calibras will already know that the airbox-->turbo pipe is a weak point and under serious load it can collapse and result in power cut-offs.
Therefore any LET worth its salt has already got an aftermarket pipe, re-enforced and even silicon-based perhaps.
...which brings us to the following question: what to do with the old, stock, crappy pipe? There's nothing wrong with it, it just can't stay in shape feeding the turbo with all that extra airflow
High-boost turbos need an extraordinary amount of airflow to pass through the airbox, especially at full load at high revs (and high speeds).
The stock airbox might be OK for 1.6 8v, but can hardly satisfy the stock V6, let alone a turbo doing 1bar+
Enter the Cold Air Intake
Take the bottom part of the airbox (without the snorkel)
Add the snorkel from a V6 (dunno if the 16V is the same, it probably is - this one was kindly donated by Kingsley)
This setup results in the round part of the snorkel pointing downwards
...Guess what this is
It's the old airpipe fitted through the bodywork.
Nothing was cut, everything fits like a GLOVE! lmao
The snorkel fits exactly, like it's been designed for this purpose
The pipe's shape is almost ideal, as it snakes through the frame and rears its little head right under the tow-hook :
Now it's a matter of fitting an attachment to help it face 100% forwards.
1. It's FREE
2. It flows well, as all parts were designed to flow air
3. Nothing's cut or bent, easy to revert to stock
4. Using the stock airbox, the water holes will take care of water in case of driving in the rain (although driving in deep flood waters is not recommended!)
5. the pipe has two different diameters - it starts with the smaller one and progressively ends up in the larger one.
This is difficult to DIY, and it's very important in Ram-Air systems, as it reduces the pressure progressively
