DIY - Defi 60mm Boost Gauge Install in AC Vent
 

After perusing all options on the threads here, I decided to take a stab at it myself. My goals were as follows:

1) Minimal modifications to the car.
2) Easily reversible.
3) Should not block any other gauges.
4) Should not look tacked on.
5) Easy and quick to read.
6) Should retain the AC air flow.

The left vent gauge come off very easily. Use a pry tool carefully and pull out with your fingers.

Vent:

There are four pieces that constitute the vent. They are held together by locking tabs which separate very easily.

Take the part with the vent flaps (third one from the left in the picture above). The actual flaps are simply slotted into holes in the side and act as a pivot. Pull them out. There are two parts.

For the next step I used automotive weather seal (thick rubber) and I cut up a grippy rubber mat that I had. The type that you put on the car fender when you work on the engine. Stick this on the sides as shown.

Insert the gauge. It will be quite snug so you may have to push hard. Mine was quite firmly held with no play.

You can vary the length of the weatherstrip to adjust for air flow.

Test fit by reassembling the parts. At the same time, drill a small hole where I have, to run the wires through. The location of the hole sits outside the vent tube in the car so the wires will not be pulled in. Seal the hole around the wires. I used some Dynamat.

You can also rotate the gauge in the vent like the stock one as long as you left some play in the wires.

Sexy. Just like other mod for oil coolant and water temp. What size guage did you use? Any special tools to mount it?

looks awesome! good idea!

This might be a stupid question but I assume that the vent is now useless? And since it is no longer used did you do anything to prevent the air from going through? Because by the looks of things it seems that dust may still go through the cracks and I'm a little paranoid about varying dust/fine dirt stuck in crevices of my car....

EDIT: Other than that awesome job!

Thanks. 60mm. Tools: Scissors. Double stick tape. Brain. :)

Thanks.

Thanks. Not sure what you are asking. Read the goals that I had. Vent is not useless. Works fine.

AH! Thank for pointing it out, skimmed through that :bonk:. Everything makes sense now.

Awesome!

That was my first option then I was thinking about Gauge pods - but that just isn't right if you live in fogy / wet country... :(

BUT - its the best option for people wanting to mount single pod cheap and with the really good visibility! Great DIY! And great idea about leaving some air channels!

Can the heater part effect the gauge, since the vent is still in use?

Thanks doggy. Coming from you especially....compared to some of the things that you have done. lol.

When you say effect, do you mean functionally? If so, not in my case. Of course time will tell.

Wow this is great good work!
