I came across this picture of a questionably modified V36 coupe on a forum recently.
When the issue of the hood gap surfaced, the explanation by a member certainly grabbed my attention. The improper justification for the poor-fitting Top Secret replica hood was qualified with, "I read it somewhere."
"The gap is for increased air flow in the engine compartment. The air goes in that gap and the grille and comes out the top vents. Nothing caused it. It was designed that way. You can look at the picture and see that."
Explanation for the mis-information being spewed by this ill-advised member: Because forums.
Explanation for the hood fitment issues: Because SEIBON.
In short, just be cautious, wary, and skeptical of what you read on internet forums.
