Once on 1-2 year on regular spark plugs. Once every there years on High end spark plugs.
According to the owners manual, they have platinum plugs that should be changed at 100,000 miles.
About every 50,000 miles.
about every 75000 miles
A standard spark plug should last about 50K. A platinum tip plug should last 100K.
every 100,000 km
With the new fuel injected engine and improved ignition systems you should be able to go 100,000 before tune-up
The manufacturer recommends that the spark plugs are changed every 30,000 miles. Many individuals have experienced a much longer life for the spark plugs.
I just spoke with a Parts person at a local Toyota dealer. He told me that the 2004 Toyota Matrix requires Iridium spark plugs, which retails for about $12 at the dealership, and it should not need to be changed until 120,000 miles.
100K if they are platinum plugs, 50K if they are regular plugs.
The spark plugs on a 1999 Mercury Cougar are located under the cover of the engine. The spark plugs should be changed approximately every 60,000 miles.
