Well, spent my day today on a few things including cleaning the air filter, ptp turbo blanket and a whole lot of DEI Reflect-a-Gold wrapping.
After reading about this on IWSTI (Here:
http://www.iwsti.com/forums/2-5-liter-litre-factory-motor/245621-diy-heat-managment-cobb-sf-intake-airbox.html) I decided to tackle this myself. Before I did all of the work I took a 30 min drive on Saturday, and got the following air intake temps using the accessport:
Ambient Temperature: 57 F
Cruising Temp (50 km/h): 95-100 F
Stop Light Temp, 1-2 minute stop: 125-135 F
Standing 5 Minute Idle: 165 F
After all of the gold wrap and turbo blanket I went for a similar drive and got the following numbers:
Ambient Temperature: 60 F
Cruising Temp (50 km/h): 80-88 F
Stop Light Temp, 1-2 minute stop: 95-105 F
Standing 5 Minute Idle: 144 F
Was it worth my time and money? That is certainly questionable and subjective. The numbers speak for themselves, there is a reduction across the board for intake temperature. A real comparison would probably need a dyno, but I did not want to spend any additional funds to justifying my previous spending.
Here are a few photos of the process. Did not remember to take pictures at all stages, but feel like this is a good summary.
Cleaned the intake box first:

Next up is the turbo blanket install, intercooler out:
Turbo blanket in after much swearing and a call to Assunta. It seems I had it in my mind that I needed to wrap in around the turbo completely. That was a frustrating waste of 60 minutes, possibly more:
Decided to gold wrap the inside of the heat shield while it was out. I was able to re-install it over the turbo blanket, even though everyone said it was not possible. (it was previously modified to install aftermarket downpipe)
Saw a video on removing and installing the TMIC and it showed that removing the driver side TMIC support bracket gives a more room making it easier to re-install the TMIC.
Wrapped the bottom of the intake scoop for the airbox with the remaining gold foil tape.
Everything put back together. I do like mods that you cannot "see" as I prefer to keep as stock of an appearance as possible:

It would have been a very short day if I did not continuously struggle with the turbo blanket, which seems a bit ridiculous. I was hoping to get on my S204 side markers on today, but that is reserved for next weekend when I do the winter tires and coilover covers.
Next small project is 3M-Dinoc CF wrap the shifter trim similar to the photo below. Going to save this project for the first weekend of crappy weather this fall/winter. After I have done that I plan to try and wrap other parts of the interior but not go too crazy.
