Used injectors should never be installed blindly. Even when they look clean on the outside, they may suffer from restricted flow, poor spray pattern, leaks, contamination, or uneven performance from one injector to another.

Our injector cleaning and review service is designed to inspect supported injectors, identify common problems, and restore performance where possible before those issues turn into drivability problems, poor fuel delivery, unstable idle, misfires, excessive fuel trims, or uneven cylinder performance. This is especially important for used injectors, long-stored injectors, or sets with unknown history.

Whether you are reinstalling used injectors, buying a secondhand set, or trying to recover a questionable set, proper testing and cleaning helps you make a better decision before they go back into service.
