Just for some more info, here's what was in the release I recieved a few months ago...
"Dynomite Diesel Performance is proud to introduce their new 6.7 liter Cummins Injector Nozzles. These nozzles will produce an extra 50 horsepower and 80 foot pounds of torque on your Dodge truck. This power increase is accomplished by using a very precise technology called Extrude Hone. This advanced technology allows them to achieve a small radius inside of the fuel exit passage, which promotes better atomization for more power and better mileage. According to Dynomite, the high performance nozzle set burns so clean that it won’t harm or clog the Diesel Particulate Filter. Installation time is around 4 hours and a tool is included to help swap the nozzles onto your injectors."
I haven't gotten an updated price sheet lately, so I'm not quite sure on the price, but what was stated above sounds right.
