Default stupid n00b intake question

the k&n typhoon intake makes a whooshing sound.
so i was wondering what is it that causes the sound, the fact it has a cone filter, or its bigger intake tube, or the combo of the two?

The wooshing you're hearing is just becuase of the cone filter. Stock air boxs are designed to dampen those sounds for a nice quiet ride.

i would not just rip out the box and slap a cone filter on there. The MAF depends on have the correct airflow across it, and you don't know what you would be doing to that airflow without testing.

Maybe i'm wrong, but that dosen't seem to make any sense The MAF is a sensor that measures how much air the engine is drawing in. It dosen't need a certain amount of airflow, it just tells your ecu how much air is flowing. If you add a cone filter and increase the amount of air being drawn in, the ecu will just compensate by adding more fuel=more power.

It's rumoured that some intakes will cause turbulence going past the MAF sensor and sometimes (it's inconsistent from what I've read, some cars will do it, others won't) it will trip a CEL.

I know that the Cobb and the K&N short ram intakes both claim that they will not throw CELs due to their design and placement blah blah blah of the MAF sensor.

Thus far I haven't had any problems with the K&N Typhoon. Makes some nifty sounds and powerwise, it's hardly noticeable. Kind of a "maybe?" feeling. But it didn't get worse, so whatever.

It's not rumored it's been show many times that by introducing turbulence you will change the way the MAF reads air flow. This causes your MAF, and consequently ECU, to incorrectly measure the air flow. That's while the number of WRX "safe" intakes is very short, you can run others, but they require proper tuning to account for iregularities.


And the MAF doesn't directly measure airflow, it requires a number of things to remain constant for it to work properly.
