    Cummins wants about $600 for a new doser, part # 2888173.

    Bosch? Roadwarrior? Dinex? There is an ocean of these on the aftermarket in the $200 range. Does anyone have first hand experience with one that ended up worth the money?

    Can’t say about emissions stuff but if it pays the bills and can stop me from paying the bills it gets oem parts no mater the cost… not even a question. But only from a dealer parts countertop. (I’ve been burned buying oem off line)…

    tail lights, bumpers, window regulators, headlights, No problems taking a chance aftermarket.

    Injectors, fan clutches, engine sensors? New oem if I can get them!!
