Ok i ahve made up my mind to get K&N Cai for the euro. How much difference does it actually make? does it give the car a but more urge or will i notice a difference in acceleration? will it alter 0-100 time ? that is hoping for a but too much for a basic mod but i can only hope :P this will be my first ever mod. Ok simply i go to powerbarn ask them for K&N Cai for euro (they order it) and also fit it in for a price i assume for me.
Is there any other mods which gain some performance in the car (under 500 dollars)
which i should look into?

Thank you for advice
