I'm curious as to what figures were obtained by the "Independent Dyno tests show an increase of both HP and torque." It would be nice to have the information. Still its going to be hard to beat the Brand X up Pipe for ROI as far as spending your $$$ go.

While I am a huge fan of PT Tuning and I have seen this new piece live, here's my understanding of cold air intakes after doing a ton of online research.

1. The best source for cold/fresh air, without adding hood scoops, cowl induction, etc. is the factory setup via the front wheel well.
2. PTDiy has a great article on rising temps under the hood in stop/go traffic. In a nutshell - it gets HOT under the hood if you aren't blowing air through it.
3. Air flow, velocity, etc are greatly affected by the configuration of the intake hose. The factory accordian is not as desirable as a smooth pipe.
4. K&N (or equivalent) filters allow more air through with less restriction than the factory filter. More air = good.
5. Basically you want cooler air and a smooth flow to the intake.

Aftermarket options appear to be:
1. BTG (and similar) CAI with the smooth pipe and the K&N style filter. The downside I see to this is that the filter isn't really drawing a lot of truly cool air; it's just sitting in the engine bay which gets mighty hot in stop/go. About $260.00
2. Airaid CAI. I like the fact that it attempts to insulate itself from the engine compartment as much as possible and draw more air from the wheel well, but it uses the stock factory snorkel, which has the accordion and thus impedes air flow to a degree. About $140.00
3. Use the Airaid coupled with the BrandX pipe. Cooler air, low restriction filter, smooth pipe. About $240.00 for the combo.
4. Leave the factory air box, drop in a K&N (or equivalent) and use the BrandX pipe. Cool air in, low restriction filter, smooth path to the intake. About $130.00 for filter and pipe combo.

I think I've finally made up my mind.

Just trying to keep you out of trouble. We seniors have to stick together.

Ya, I came to the same conclusion as Mike. I think aftermarket option #4 is best for most applications.

I think the Typhoon type intakes may be better for the upper end, since the warm air is not hanging around the engine bay and you have the most free flow.

Mighty hot is a good way to put this... I spent 3 weeks comparing the intake temp of a stock setup vs the BTG and found that the BTG averaged 20 degrees hotter over outside temp. The big difference was in stop-n-go where it was often over 160F around the BTG filter compared to the stock filter hanging in at around 120F. This is on a 85-90 degree day.

I'm not sold yet on CAI for turbos.. The intercooler takes care of this (I'm asusming those temp readings are at the air filter). Plus, it's not power off idle that my pt needs - it already spins tires like a beast no matter how much stop and go traffic I'm in. A short ram will support all the down low power you will ever be able to hook up I would think, the FMIC will reduce the temp like it's supposed to do, and the short ram will flow like a mofo at the higher rpms where the pt starts to peter out (and now your moving so the underhood temps have dropped anyways, particulary if you pulled the weather strip). I still believe in airflow over all else, let the FMIC do it's job
BTW: there's a SRT over in the srt forums that just recently dynoed at 450 hp..
