Please be sure to include the completed order form inside your package. If you do not have a printer, please write out your name, address, phone number, and email on a piece of paper and include it in the package.
✅ Leave O-rings and spacers attached.
This ensures accurate matching during reassembly.
✅ Dry and bag each injector.
Place each injector in a separate plastic bag to prevent gasoline odors and cross-contamination. For easier reinstallation, you may label each bag with the cylinder number.
