Noticeably difference in performance.
Stock, 2019 F250 (6.7 Diesel of course) with 53,800 miles. Since I purchased the truck the turbo gauge / boost at best only went to half way, even under heavy load. Recently found the factory intercooler hose cracked. Ford wanted $180 for stock replacement. H&S offer performance and warranty for only $100. Now the boost / turbo gauge goes up to 3/4th and you feel more power performance. Should’ve replaced the intercooler day after I purchased the truck!
