Fuel injectors do exactly what their name suggests, as they deliver fuel into an engine's combustion chambers to be burned. Fuel injectors can cause a whole host of problems that can lead to major engine damage if not diagnosed and replaced or repaired as soon as possible.
A dirty fuel injector can cause fuel line problems such as misfiring, hard starting, stalling and hesitation. If you are hearing other noises, such as clanging or high idling, you might want to check other areas of your fuel system.
Each injector comes with new seals. This injector can be used as an upgrade on the EA113 2.0T motor, if you're running BIG power! These ones don't blow black smoke like the older version of the "RS4" injector, which has the same connector as the EA113 2.0T. These injectors have a different plug/connector, so we include a new connector and a short length of wire with each one - you will need to wire these in to your existing harness if you wan to use them on your EA113 2.0T. This is a "stage 3" injector
