The product will appear as depicted in the images provided, which have been cleaned and tested, and it comes with a 30-day guarantee. It will closely resemble the image above. As part of our quality control process, we conduct leak tests on the fuel injectors. This step ensures that their functionality remains unaffected by any leaks or potential issues. Additionally, we assess the injectors for current draw, shorts, and inductance to confirm they meet our stringent standards. We also perform tests on injector flow rate and spray pattern, preserving the results for future reference.This comprehensive testing protocol guarantees that our injectors are of the highest quality and will perform optimally in your vehicle. We execute a dynamic flow test on the injectors, operating them at various duty cycles and pulse widths for 30 seconds, allowing us to assess their performance across different conditions
