Injector Servicing
& Cleaning
Every injector that comes through the shop goes across our ASNU machine — ultrasonically cleaned, flow-tested, and matched as a set. You get real numbers back, not a guess. As a Fuel Injector Clinic authorized dealer, we service what we sell and everything you send in.
Sets of 4, 6, or 8 · drop off or mail in
Full Injector Service, Done Right
Set-of-8, set-of-6, or set-of-4 — foreign or domestic, high-impedance or low. $150 flat for port injectors: we tear them down, clean them on the ASNU, replace wear parts as needed, and prove the result on the bench.
Ultrasonic Cleaning
Injectors are back-flushed and run through an ultrasonic bath to strip out varnish, ethanol residue, and deposits that no bottle of cleaner will touch. Clogged pintles and screens come back to life.
Flow-Bench Testing & Matching
Static and dynamic flow measured on a calibrated bench, then matched across the set so every cylinder sees the same fuel. Spray pattern and leak-down checked at pressure.
Wear Parts As Needed
Seals and wear parts that dry out, crack, or leak get replaced as needed, so your set seals clean and holds pressure when it goes back in.
Before/After Flow Data
You get a printed report with each injector's flow before and after service, and the matched set variance. No mystery — you see exactly what you're bolting back on the engine.

Local to Rialto? Drop them off. Anywhere else? Box them up and ship them in — we service them and send them back with the data. Same shop behind socalinjectorcleaning.com.
Your Tune Is Only As Good As Your Injectors
An engine can't correct for fuel it never got. Dirty or mismatched injectors sabotage a tune before the first pull — the tuner ends up chasing a problem the hardware created.
Dirty / Mismatched
- Rough, hunting idle and cold-start stumble
- Cylinder-to-cylinder AFRs all over the place
- Lean spots that pull timing or hurt parts
- Wasted dyno time chasing a hardware problem
- A tune built on numbers that aren't real
Clean / Matched
- Even, steady idle and clean cold starts
- Consistent AFRs across every cylinder
- Known flow rate the tuner can trust
- Full power without lean-cylinder guesswork
- A tune dialed on data, not assumptions
