THE MANUFACTURER WAS CONTACTED VIA EMAIL AND INFORMED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 12,000. *DT*JB VIN NOT AVAILABLE. CONSUMER STATED THE LATEST IS PART OF THE OVERHEATING MAY BE DUE TO THE SOCK ON THE AIR INTAKE. IT WAS ONLY SUPPOSED TO BE USED ON THE INTAKE WHEN THE COMPLETED FRAME WAS SITTING OUTSIDE, WAITING FOR THE BUILD. IT WAS ON THERE TO KEEP THE BUGS, BIRDS AND CRITTERS OUT. NOT SURE OF THE TRUTH ON THIS, BUT I REMOVED THE YELLOW INTAKE SOCK OFF OF MY MOTORHOME INTAKE TODAY.*JB *DT*JB
