Fixed written price before any work — no obligation.
The set-price myth
There is no honest set price for a spark plug replacement — and anyone quoting one sight-unseen is guessing with your money. On this job the figure genuinely moves with plug type and count — iridium sixes cost more than copper fours; access: some engines hide the rear bank; and coils worth doing in the same labour on aged engines. So we don’t guess: we put the car on the hoist, confirm exactly what the job needs, then you get a fixed written price for your car before any work starts. The written figure is the only number that binds anyone — hold every workshop to that standard, including us.
What drives the cost
Spark-plug cost depends on the number of cylinders, plug type (standard vs iridium/platinum long-life), and access — some engines need intake parts removed to reach the plugs.
Using the correct manufacturer-specified plug matters; the wrong plug causes running problems.
