Petrol Injector Cleaning & Flow Testing in Sevilla
Ultrasonic clean, flow-tested and re-sealed — like-new spray pattern.
We provide petrol injector cleaning & flow testing in Sevilla through our convenient mail-in service. Pack it up, send it to our Costa Blanca workshop, and we'll return it cleaned, tested and protected with tracked delivery to Andalucía.
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'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.
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.
