Professional installation and injector or ECU calibration may be required.

This product is covered by a 6-month limited warranty from the date of delivery. The warranty covers confirmed manufacturing defects under normal use. Returns and warranty claims are subject to the XAVORNIK Returns & Refund Policy.

Frequently asked questions

How do I confirm fitment?

Match the original part number, the relevant engine or machine model, and any required serial information. Compare the product dimensions, mounting points and other fitment details shown on the product page. Contact XAVORNIK before ordering if you are unsure.

What should be checked before installation?

Inspect the product for damage and confirm that the supplied components and physical configuration match your application. Follow the product-specific instructions and the relevant installation specifications. Do not install a damaged or incompatible product.

What does the warranty cover?

6-Month Limited Warranty

The limited warranty covers confirmed manufacturing defects. Normal installation or use does not, by itself, cancel the right to submit a manufacturing-defect claim.

See our Return, Refund and Limited Warranty Policy for warranty periods, coverage, exclusions and claim procedures. The limited warranty is separate from the 30-day non-defective return request window.
