Honestly, performance air filter...

[richypanic]

Is there really any gainable difference in fitting a K&N etc air filter on the 2.0 SX ABF? Tempted to replace/modify the factory box on occasion as its a bulky beast. Other than affecting the sound of the engine?

 

[andycupra]

most likely no.

 

[Icecavern]

No.

hows about just uprating the air filter in the airbox? would that make any difference? instead of replacing with a cone?

Still wont increase performance, unless the filter already in there is virtually blocked anyway.
