Frequently asked questions

How do I find the right injector?

The quickest way is the OE number stamped on the injector or printed on its label. You can also search by a cross-reference number – it opens the product page with that number. You enter the VIN in the order. If it does not match the part, we contact you and arrange a change of the order.

What does 4x or 6x in the name mean?

The number at the start of the name is the number of pieces in the set. The price is for the whole set, and the price for 1 piece is also shown on the product page. The number of pieces matches the number of engine cylinders; extra pieces can be added individually.

What is the difference between a new and a used injector?

A new injector is an unused part. A used injector is an original part that has already been in service. The condition is shown on every product, and the warranty differs: 24 months for new and 12 months for used parts.

What warranty do you give?

24 months on new injectors and 12 months on used injectors, from receipt. Make a complaint by email to info@iject.eu with the order number. This does not affect the consumer's statutory rights.

How do shipping and payment for American Samoa work?

Shipping 111,56 USD, FedEx. Delivery within 10 days. Payment is by bank transfer in advance. We send the shipment only after the payment has been received. The goods price is the export price. Czech VAT is not included. No verified customs-duty rate for American Samoa is on file, so no duty percent is shown. Any customs duty set at clearance is paid by the consignee. It is not in the IJECT price or in the shipping amount. No verified import-tax rate for American Samoa is on file, so no tax percent is shown. Any import tax the customs authority sets is paid by the consignee. It is not in the IJECT price or in the shipping amount. No verified carrier clearance fee is on file, so no clearance-fee amount is shown and none is added to the order. If the carrier charges one at delivery, the consignee pays it to the carrier. The goods ship from the warehouse in the EU. IJECT has no stock in the destination country.

Can I return the goods?

Yes. A consumer may withdraw from the contract within 14 days of receipt if the part was not used and is in its original condition. Write to info@iject.eu with the order number.

How do I check that the part fits my vehicle?

Compare the OE number on your original injector with the numbers shown on the product. The list of vehicles and engines is for guidance. You enter the VIN in the order. If it does not match the part, we contact you and arrange a change of the order.

Do the injectors need to be coded?

Coding requirements differ by engine management system; we will specify them once the part has been identified. Coding is carried out by the customer's workshop.
