Well I've been reading up as much as I can find on the Colorado Outlaw Airbox Mod and it's interesting me a lot. I just haven't seen anyone do this on a V6 and document it.
I did this to the V6, and the process was identical to the 1.8T, that is why it was never documented. As for having a bigger airbox, that is not really what we need, as the airbox is huge now and already fills the coffers of 8 cylinder engines as is.
One reason for such a large box is the amount of filter surface area you get by using a pleated element inside this box. If you unfolded the stock filter, there is a ton of paper exposed to work with.
The drawback is that the stock air intake (more so on a modified engine) is on the verge of not being able to get enough air into the box, that is why we have the Colorado and Minnesota airbox mods.
Well, the Colorado mod is designed to get more into the box, and the Minnesota mod gets the air out of the box and into the MAF.
However, the V6 airbox already has the factory equivelent of the Minnesota mod on it, as such, the only mod we can do is the Colorado.
The size of the box is not a real concern, the size of the opening into it is, that is what we were working on fixing.
Another solution was to remove the box altogether, but then the amount of hot air getting sucked into the MAF usually negated the benefits of removing the snorkel, etc.
