I just found out something very shocking!
i went to get my grandfathers 7th gen civic tuned from my local honda dealership and there i saw atleast 3 9th gen civics parked with their engines ruined. The mechanics told me that the "air box" which is located at the level of the headlights of the 7th gen is located at the level of the fog lights in the 9th gen.
The mechanics very strictly asked me NOT to drive in flooded areas
apparently the water enters the "air box" and then goes into the main engine block ruining the con rods and pistons. the mechanics have to replace it all
for details and pics to see what i am referring to to , check out post 543 here: My father's 2013 Honda Civic VTI oriel prosmatec with navigation
