Hey guys,
My k&n airfilter arrived today but I am hesitating to install it after reading some more...
My concerns are:
How will it deal with rain? I live in Belgium so we do see alot of rain here...
Will it run to lean if I leave the O2 sensor inside the airbox?
Will it run worse then before because the ecu won't be remapped?
I hope some guys that have done the mod can enlighten me...
