6 Pieces Fuel Injector 3921421 for Cummins Engine ISC 8.3L
Condition: New Aftermarket Part
Note: We recommend replacing the entire set of fuel injectors to ensure the engine's optimal performance. Due to differences in oil output and atomization concentration between genuine and aftermarket parts, they should not be mixed. Replacing the entire set of injectors helps avoid potential issues. Always use clean oil.
