  • Saddle Jet Plugs (6 pack) for 5.9L & 6.7L Cummins Diesel Engines '03 to '13

It’s the little things that will bite you -- Please don’t break down just because you don’t have these!  

APP’s Saddle Jet Plug replacements will last because they are made from 7075 Aluminum.  Your ’03 to ’13 Common Rail Cummins engine came from the factory with PLASTIC saddle jet plugs.  The saddle of the 6 main bearings was drilled for an oiler, but those engines didn’t use oilers there, so the factory plugged the holes with plastic… You can fix that! 

With the heat generated from performance engines, the plastic plugs can deform or melt leaving an open hole from the main bearing which releases oil pressure….the bearings can fail and leave you on the side of the road.  You don’t want engine oil pressure issues!  Correct the weakness of the plastic plugs now when you’re working on your engine,

Engine must be disassembled to install.
