Spark plugs, iridium (V6, incl. rear bank access): how much does it cost?

Typically NZ$320–NZ$870 in New Zealand and A$310–A$870 in Australia, including GST. Most cars.

Parts (trade)LabourSubletTotal incl GST
New ZealandNZ$130–NZ$2701–3.5 h—NZ$320–NZ$870
AustraliaA$115–A$2401–3.5 h—A$310–A$870

Totals use a standard workshop rate of NZ$120 or A$140 an hour and a 25% parts markup, plus GST. Your workshop's rate and parts prices will differ.

What affects the price

Six iridium plugs. On transverse V6s the rear bank sits against the firewall and the intake plenum often has to come off (plus a plenum gasket), which takes 2-3.5 h. Longitudinal V6s are about an hour.
