Hi guys, im new here, found the website last night and its a great read
I have a 2011 Zafira 1.7ecoflex and will soon be getting it remapped but before i do i wanted to change a few bits under the bonnet to maybe get a little more bhp from the remap, ive seen some people talking about changing the airbox to a 1.9cdti box, are they bigger than whats on my 1.7? also some says to change the intake pipe for a larger vxr one.
is it a simple swap and away you go or is there modifications involved?
Cheers guys.
