MPG with new air filter

Ok so I just recently fitted my Pipercross Viper kit to my 1.4 MPi.

Was wandering how much of a difference it will make to the MPG??

I have noticed it uses a bit more fuel by just watching the fuel needle (I think not sure though...)
I think I'm gonna work it out sometime, but just means I have to put the original back on.


Cheers,

to be honest, i doubt it will change much,

main reason for it changing is you've probably changed your driving style, so you can listen to the filter more! much more harder accelerating i bet
