Quick Ship SKU #: GM-97188463 Factory Replacement Injector Cup 01-04 6.6L LB7 GM Duramax

The factory injector cups are very prone to pitting and becoming seized onto the injector itself. Save yourself the headache of trying to repair damaged cups, especially when replacing or servicing your injectors by also replacing the injectors cups. Injectors cups are sold individually and we recommend also adding two new o-rings for each cup to avoid any leakage.
