DescriptionIt should go without saying that correct operation of fuel injectors in any performance engine is crucial, yet often over looked. A partially blocked injector in a road engine usually means poor running. In a race engine it can can mean a blown head gasket or melted piston!
Note: This service is for PORT injectors, which do not include later style direct-injection (DI/TFSI/TSI/etc.) injectors, sorry!
At EFI we’re able to accurately test both the flow and spray pattern of your petrol fuel injectors to check for balance and performance.
Stuck or blocked injectors can more often than not be restored to full working order with a deep ultrasonic clean whilst connected to our industry standard ASNU injector service machine.
This service is ‘per injector’ and includes the following:
- Before test of injector flow and pattern.
- Ultrasonic clean *for as long as necessary* to restore operation.
- ASNU machine constantly triggers the injectors with a “cleaning cycle” while injectors are subject to ultrasonic cleaning. This helps to make sure that every trace of contaminant is removed.
- Injectors are re-tested for flow and pattern. If all is well we will then fit new serviceable parts where appropriate (pintle caps, O-rings, filter baskets, etc.)
- Injectors are tested for a final time for flow and pattern. Data recorded.
Just about all types of petrol fuel injector can be cleaned and serviced by us including early Bosch, Rochester, Denso, Siemens, Injector Dynamics and side-fed injectors. If in any doubt please drop us an email first.
