I just picked up a fujita intake, first thing i noticed is how small it looked. So i measured the inner diameter of the stock intake and of the fujita. I couldnt believe what i saw, take a look...
The fujita intake has an inner diameter of around 2.5 inches, while the stock intake has an inner diameter of around 2.875 inches.
When you do the math, the stock intake area is 6.5 sq inches while the fujita's is 4.9 sq inches. The fujita intake is 25% smaller then the stock intake.
How on earth can the maf accuratly measure the air now? The area that it sits in passes 25% less air then the stock intake.
I cant believe that a company that specializes in intakes f@#$ed up like this, its insane. If the gxp wouldnt have a wideband o2 sensor the car probably wouldnt be driveable since the airflow is miscalculated.
