For the air box mount what do you think about these:

Has a plug for a flow sensor... maybe a IAT before turbos would be cool

Any thoughts here??

Thanks guys
Your engine needs to know the IAT post turbo....not pre turbo.....

It will impact your A/F ratios

probably too short

PVC options

http://www.nostalgicairparts.com/air...flange-731.php
only 2.5" ID and the height is a little small. But 2.5" may work better for routing and still give good results.

http://www.aircraftspruce.com/catalo...uctflanges.php
VERY good option it seems

The other rout would be a custom flange from a machine shop, but that will be costly.

I would think with the right part, you could secure the hose adapter with the fit between flange, hose, and clamp... no sealant necessary. 2 3" o-rings could be used around the air box with the clamped hose holding the assembly. Any thoughts here??

Thanks guys
The easiest one is the Spectre 8148 mounting plate, sold at any pepboys or autozone for 6-7 bucks.

It would only be for reference... this would be more accurate then ambient temps.

It really is. You can read up all you want about how to please a woman, you can look at all the diagrams in the world, but just like the clitoris, you won't know what the hell an apex is before you actually find it.

i don't know if it's a good idea or not, but for people having a BOV and the mr5 intake (or not), in addition to all of that, is it possible to install small/mini airfilters instead of caps that plug the intake inlet holes (where excess air are normally sent with the OEM DV) ?
Should add a bit of airflow too ? (like a mini Mr5 concept)

Yes, my bad comparing this to the original mr5 intake.

It's more like an mini Helix intake style car, filters would be located in the engine bay.
