if you are worried about your warranty then dont even open the bonnet, soon as you modify your car you need to accept that your warranty is gone, cause if you get a hard ***** dealer its as good as gone.
Not true! I am fully covered with AAMI, all my mods are disclosed and covered, so long as the parts do not make the car unroadworthy. Normally a pod filter is not acceptable, but being essentially enclosed behind the foglights they are. I also have lowered suspension and front and rear sway bars. I believe Danthuyer has many more mods that are all covered too.
all of my mods are covered also, just costs bit more
