That's correct, they're dry filters!

 

Hey Guys,
Phil here from Fabspeed. Our Competition air intake are dry filters we have moved over to the Y intake over the J style. No need to worry about oil. All you have to do is air blow them out in order to clean them. You do not need to wait for them to dry.

Hey Guys,

We have changed from the J-style to the Y to increase the airflow into the intake as much as possible.

The J style was a great to capture the air from the intake fan, however the y setup with the two filter increases the air flow by capturing both sides of the trunk inlets and the intake fan.

The more air the better.

 

CAI have already been debunked that they don't add any power. Even the IPD and GT3 TB. Open filters also add more heat soak.

 

My ears don’t care if there isn’t any more power.

the fabspeed intake has an addictive tone and literally screams.

This is a very interesting video. My qualm with it is that your car is not sitting still with no air flow while driving. When running on the dyno you need to have some air flow going over the vehicle. The intake is made to allow more air to flow into it. If the car is sitting still with no air flow it would be impossible to get more air in.

I am not denying their result, they makes sense. Their testing is the issue. Asking a car to "pretend to travel at high rate of speeds" while not supplying extra air you will choke the car out. If we increase the ability to pull more in but don't supply the air you will get the same results.

The ambient air is going to be hot.

 

do you have any leftover J styles for sale?

 

Unfortunately, we do not. We have not had them for at least three years.

 

That is indeed true as air flow is essential for 911's. This video proves more of the heat soak which is a common con with open airboxes, esp short ram intakes. There are CAI reviews with dyno + air flow and even field test applications with NA vehicles (front engine) that should benefit from direct air flow yet didn't gain significant power.

 

The Y intake looks more balanced, but my experience with both is that the J works better for me. I think the longer single pipe with more gradual curve straightens the air better and with less turbulence prior to the throttle body. My car actually runs stronger with the J-pipe than with the Y-pipe and why that's the setup I use. Maybe it has something to do with the supercharger setup since my car isn't stock.
