6.7 Cummins owners beware of your intake-heater bolt failure! On the stock intake heater, the bolt on the bottom will melt and drop into your engine causing total engine failure! With the BD diesel intake-heater kit, it eliminates the bar that feeds power to the top of your heater and gets rid of the bolt that causes this engine failure. Get it replaced before it's too late!

6.7 Power stroke (2011-2024) owners, upgrade your failure prone CP4 injector pump. When the CP4 fails, it sends metal throughout the fuel system and damages it. This causes the whole system to need replacing. Get on top of this problem and upgrade to the S&S DCR pump, eliminating catastrophic failures!
