Petrol Injector Cleaning & Flow Testing
Ultrasonic clean, flow-tested and re-sealed — like-new spray pattern.
Clogged petrol injectors cause rough idling, misfires, poor MPG and failed emissions. Chemical fuel additives barely touch baked-on lacquer and carbon. Our ultrasonic process strips deposits from inside the injector body and pintle, and every injector is flow-, leak- and spray-tested before and after so you get measured, documented results — not guesswork.
We clean and test port (multi-point) petrol injectors and motorcycle injectors for engines up to ~4,000cc, up to six at a time. Every service includes new seals and o-rings as standard.
What we clean
- Car & van port/multi-point petrol injectors
- Motorcycle & scooter injectors
- Classic & modern EFI systems
- Top-feed and side-feed injectors
- Performance & tuned injector sets
What's included
- Ultrasonic cleaning of injector internals
- Pre- and post-clean flow test (volume/min)
- Leak-down (seal) test
- Balance/uniformity test across the set
- Spray-pattern (atomisation) check
- New pintle caps, filter baskets, seals & o-rings
- Before/after flow report with your job
Our process
Inspection & baseline test
Each injector is bench-mounted, pulsed and its initial flow, leak and spray pattern recorded so we can prove the improvement.
Ultrasonic cleaning
Injectors are cleaned in a heated ultrasonic bath with the coils pulsed, driving cavitation through every internal passage to lift lacquer and carbon.
Back-flush & re-seal
Compatible injectors are reverse-flushed, then fitted with new filter baskets, pintle caps, seals and o-rings.
Final test & report
A full flow, leak, balance and spray-pattern test is repeated and the before/after figures are documented with your return.
Benefits
- Restored throttle response & smooth idle
- Better fuel economy and lower emissions
- Measured, documented flow figures
- Far cheaper than new OEM injectors
Frequently asked questions
Do I need to remove the injectors myself?
Yes — for mail-in and most drop-offs we clean and test the injectors only (removal/refit is a workshop job). We can recommend a local garage if needed.
Can you test GDI / direct-injection injectors?
We can ultrasonically clean them, but high-pressure GDI injectors cannot be flow-tested on our rig — we'll tell you honestly what we can and can't verify.
What if an injector is beyond saving?
The flow test reveals dead or badly leaking injectors. We report it — you only pay for cleaning attempted, and we never charge for a part we can't improve.
Diesel Injectors
Deep ultrasonic decarbonising of diesel injector bodies and nozzles.
Carburettors
Every jet, passage and emulsion tube cleared — carbs that run right again.
Motorcycle Carbs
Banks of 2, 4 or 6 stripped, ultrasonically cleaned and rebuilt.
