thank you
A standard spark plug should last about 50K. A platinum tip plug should last 100K.
About every 50,000 miles.
about every 75000 miles
I would replace the spark plugs after 50K, the wires and plugs again at 100K.
According to the owners manual, they have platinum plugs that should be changed at 100,000 miles.
Once on 1-2 year on regular spark plugs. Once every there years on High end spark plugs.
With the new fuel injected engine and improved ignition systems you should be able to go 100,000 before tune-up
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.
every 100,000 km
Under the hood around the engine compartment there should be an emission information sticker that will tell you what the recommended spark plug gap should be.
