Mercedes 300SD W126 - OM617 Injector Nozzle Replacement/Upgrade

#impalamansgarage1 In this video I replace the diesel fuel injector nozzles. We replaced the original SD240 nozzles with SD314. The effect is a noticeable increase in off-idle pull away torque. This is especially evident in the hilly area around here. Being able to pull up a hill in 3rd gear without shifting down to 2nd is pretty nice.
