Oil, fuel filter, water separator, DEX-COOL, the Allison 10 speed and DEF on the 2020 and newer L5P Duramax: what to service, when, and the parts that make each job easier.

Oil, fuel filters, coolant, boost leaks, CCV, transmission and DEF on the 2020 and newer 6.7 Powerstroke: what to service, when, and the parts that make each job easier.

Oil, both fuel filters, the CCV filter, coolant, transmission and DEF on the 2019 and newer Ram 6.7 Cummins: what to service, when, and the parts that make each job easier.

The factory plastic intake piping is one of the weakest parts on a 6.7 Powerstroke. We compare the four full piping kits we recommend, SPE, MPP, No Limit and Pusher, plus Pusher charge tubes if you only need one side fixed.

The factory oil filter setup on a 6.7 Powerstroke makes oil changes messy, and the housing is a common leak point. Here is how the SPE billet housing changes that, which version fits your truck from 2011 to current, and which filters it takes.

An intake is the most common first mod on a 6.7 Powerstroke, and the most misunderstood. Here is what an open element intake actually does, when a full Pusher system makes sense, and which one fits your truck.

High oil and transmission temps while towing are a common complaint on the 6.7 Powerstroke. Here is what actually lowers them, which hoses fail, and when a coolant reroute makes sense.

The biggest airflow restriction on a 6.7 Powerstroke is not the filter. It is the intake manifold. Here is how the Pusher Powerflow and SPE OE+ manifolds fix it while keeping the factory emissions equipment and the stock tune.

FASS, AirDog and Irate Diesel compared, how to size a lift pump, and the exact kit for every 7.3, 6.0, 6.4 and 6.7 Powerstroke, 12 valve, 24 valve and common rail Cummins, and LB7 through L5P Duramax. Plus the fuel bowl deletes, regulated returns and sumps that finish the job.
