Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket fuel injector built to cross-reference OEM number 420874846, not an original Sea-Doo component. It is offered as a replacement for the Sea-Doo GTX 215 1503.

Q: Should I replace all injectors at once? A: On a multi-cylinder engine, matching flow across all injectors supports even combustion and smoother running. Many owners replace the full set when one injector fails.
