Yes, we have a 2 injector minimum.
Absolutely! Rest assured that we will take care of removing the injectors for you for a bench fee of $12 per order to do the work as problems can and often arise. However, it’s important to note that we cannot be held responsible for any potential damage that may occur during the removal process. To ensure a smooth experience, we recommend that you personally remove the injectors from the rail.
To avoid any issues with shipping service secure them in plastic and tape them to prevent leaks.
For your convenience, side feed injectors will be re-installed in the fuel rails, top feed and GDI injectors will be packaged separately. GDI Injector clips are very easy, you’ll have no issues, but they are tricky to get off which we will do if you wish.
Service prices and options are posted in store per item type. Please check the Injector id injectors page on the menu if your unsure what you have.
Turn around times are listed on the Shop page.
We always replace filters whenever they are available for the injector, this includes side feed injectors as opposed to cleaning them while still on the injector as most places do. They become fragile over time, why take a risk.
In fact we replace everything that is replicable.

When preparing the injectors for shipping, it is strongly advised to place them inside a regular zip lock bag first. This will help to keep the fuel smell contained. It is important to avoid any damage during transit, so make sure not to simply toss the bag into a box without any additional packing material. This is particularly crucial for the pintle end.
It is not recommended to ship the injectors in a bubble envelope. Optimal protection can be achieved by using a box with some padding or a bubble envelope in a box. The small flat rate box from the Post Office may be good budget-friendly option for smaller injectors.
We charge flat rate shipping per item type. Shipping charges are listed in the store per item type.
We recommend insuring the package for the exact value of the items you are shipping, so that you can easily replace them if needed in the event you need to file a claim.
