Cold Air Intakes

don't forget about the Evoms V-flow talked about here

it's not really CAI, since it doesn't dip low into the wheel well...it's just a high flow intake bro.

Technically you're right but with the air intake for the 2.0T there will probably never be a true CAI... All of the available "CAIs" just increase air flow therefore increase performance.

CAI's don't just increase airflow, they increase airflow and decrease air temp. The EVOMS intake will just help in the airflow dept. and yes the options for CAI with this engine will be limited due to it's placement and design, but eventually one will be produced.

All cold air intakes operate on the principal of increasing the amount of oxygen available for combustion with fuel. Because cooler air has more density for a given volume, cold air intakes generally work by providing cooler air from outside the hot engine bay. However, the term "cold air intake" is often used to describe other methods of increasing oxygen to an engine, which may even increase the temperature of the air coming into an engine.

Some strategies used in designing cold-air intakes are:

* increasing the diameter of the air intake, allowing increased airflow.
* smoothing the interior of the intake to reduce air resistance.
* providing a more direct route to the air intake.
* tuning the length of the intake to provide the most airflow at certain RPMs.
* using a more efficient air filter

I think we are both saying the same thing in a different way :thumbup:

CAI work in two ways... Primarily they decrease air flow resistance and secondly they slightly lower incoming air temp...

The "CAI" options out there right now achieve the one of the two goals...

I am confident there is power to be had on a stock car, but we have never tested it, nor do we actually plan to anytime soon. It makes no sense. Out of the thousands of intakes we have sold for the 1.8T, nobody runs a CAI with a completely stock car... the ECU upgrade makes the most power (bang for the buck) than any other upgrade, it doens't make sense to just do one.

I Realize that everyone running CAI are not fully modified, but "IN GENERAL" they are. One of the first questions I ask nearly every one of my customers is "what do you have done to your car already" so that I can judge where they need to go next. I also reccomend chip tuning as a first mod to guys that come to me with a completely stock vehicle. So GENERALY speaking people who purchase an intake have already or are going to be chipped.
