Air intake - what the hell?

[CMF_Toma]

Hey, i was just examining my air intake, to discover a pipe, that goes nowhere. And it got me thinking, what if i cut it off? or opened the end of it? Any gains? Any drawbacks?

That's a resonator. Keeps noise from the air being sucked into the engine to a minimum.

You're better off leaving all that in there to keep it looking stock and adding asecondary (and larger) air pipe from behind the engine up into the airbox with a pickup scoop point along the floorline of the car.

cisco did this to his white super s and apart from some critical design flaws in regards to PVC vs concrete gutters I believe it worked quite well.

i took my resonator off befor i got my induction kit and even with the original filter on it gave a deep sound when accelaration sounded mint as

I've been told that taking of the resonator alone results in losing about 10Nm of torque (which is quite a lot for a standard engine producing about 118 Nm as standard).
This goes for standard engines when you replace the standard airbox with an induction kit placed on top of the throttlebody.

Correct.

The only way you will gain any every-day driving enhancements through the way of your air intake is if you can get colder air to the throttle body.

Otherwise, leave it factory.
