Fuel Injector servicing & Flow Matching
We offer professional fuel injector testing, cleaning and flow analysis using our industry-leading ASNU injector test bench.
We are specialists in fuel injection systems and have over 10 years of experience providing this service.
Whether you're running a modern performance engine, classic road car, race car or modified application, correctly functioning injectors are essential for achieving maximum power, smooth running, reliable starting and consistent air-fuel ratios.
Our Service Includes:
Injector Flow Testing
Each injector is tested across a range of operating conditions to measure fuel delivery and identify any weak or underperforming units.
Spray Pattern Analysis
We visually inspect the spray pattern of every injector to ensure proper atomisation and fuel distribution.
Leak Testing
Injectors are checked for leakage both static and under pressure, helping prevent flooding, poor starting and excessive fuel consumption.
Injector Matching
We compare the flow rates of all injectors and provide matching data, ensuring balanced fuel delivery across all cylinders.
Ultrasonic Cleaning
Injectors are professionally cleaned to remove deposits and restore performance.
Detailed Test Report
Customers receive a printout/report showing flow figures and test results before and after cleaning.
If you're rebuilding an engine, tuning a performance vehicle, or investigating a running issue, injector testing is a cost-effective way of ensuring your fuel system is performing exactly as it should.
