Petrol fuel injectors (port injection, set): how much does it cost?
Typically NZ$430–NZ$1,420 in New Zealand and A$400–A$1,360 in Australia, including GST. Most cars.
| Parts (trade) | Labour | Sublet | Total incl GST | |
|---|---|---|---|---|
| New Zealand | NZ$200–NZ$700 | 1–3 h | — | NZ$430–NZ$1,420 |
| Australia | A$180–A$650 | 1–3 h | — | A$400–A$1,360 |
What affects the price
Port injectors are cheap ($50-150 each aftermarket); clean-and-flow service is an option. Intake plenum off on V6 adds time. Direct-injection petrol injectors are dearer, see high-pressure pump notes.
