Description:
This repair kit is used to overhaul the plugs for the injectors. As a rule, the clips break off at the plugs after the years and the rubber grommet is cracked by its kinked position on the valve. As a result, moisture penetrates to the plug contacts and cause them to corrode. If you do not want to procure a completely new engine wiring harness right away, you can use this repair kit to replace the plug-in contacts in the original way.
