I Would Remove The Grill Block. I'm No Genius When It Comes To Diesels But A Couple Of My Buddys Have Diesels And I Know That Hotter Air Going In Can Raise The Exuast Gas Temperature And If That Gets To Hot It Can Cause Damage To The Motor. The Trucks Are Engineered To Stay Within A Specific Operating Temperature And Unless You Install A Pyrometer To Keep An Eye On The EGT You Really Have No Idea How Hot Its Getting.
