Ok, I'm looking on e-bay at some injectors and have noticed before that they say hp ratings on them. Is that what they'll support, or is that how much they'll add to the truck? I found some Bosch 300 hp inj. not many specs on it though for $320. What would a good set of inj. for me be? Not looking to race with it, but I do haul heavy loads a lot. It's a work truck. Thanks!

 

that is what they give...as for what ones for you to get....im not sure on that....i havent had much experience yet...i know my 100hp made a huge difference, i havent pulled yet to see how it does, but i have a fealin it might get pretty hot..

 

Jordan, those are also known as RV 275 injectors. They are the injectors that come stock in RV's with the 5.9 cummins powerplant. They will add 40 to 60 horse over your current setup. Do you have an HO? If I towed alot, I would get them, If I played alot, I would go with some Jammer 3's. If you are set on those injectors though, buy them from someone else, PM me if you want to know where to get them for 244 shipped to your door. Or search cummins injectors on Ebay and you will find a seller called pensicola diesel, if you read a little you will notice that they are selling 300 HP injectors for 244 bucks.
