sould i restore the airbox to stoch before getting my fan module replaced.
if your getting any part replaced which is covered by the warranty, replace all the pieces related to that mod back to stock if you can. Dont give the dealer a reason to say "its because of this I cant cover it". Even if you know its not the reason whose gonna win that argument? Its costing the dealer time and money to replace so its their job to find a way out.
if the part isnt worth the time to convert it back, take the chance
