need to replace all my spark plugs on my Mazda mpv 2003 please help me.
check your coils for spark.if there ok replace the plugs and wires
Depends on the type of spark plugs. Factory plugs around 70 - 100k depending on the condition of the plugs. I would replace the spark plugs out with some AC Delco iridium plugs they will last you 100k+.
The Mazda 5 does not have glow plugs. Maybe you meant spark plugs?
Your spark plug manufacturer would recommend your replacement schedule.
You should replace the spark plugs when your car won't start first time but does eventually.
If you do not have any problems with plugs, change them when you replace the timing belt (do not forget to replace the spark plug wires too).
A Mazda 6 s requires 6 plugs, A Mazda 6 i requires 4
Every 30,000 miles or 24 months, depending on how much you drive the car and on what conditions
To replace the spark plugs on a 2000 Mazda Millenia S, first, ensure the engine is cool and disconnect the negative battery terminal. Remove the engine cover if necessary, then locate the spark plugs and disconnect the ignition coils or wires. Use a spark plug socket and ratchet to carefully unscrew the old plugs, and replace them with new ones, ensuring they are properly gapped. Reassemble everything by reconnecting the ignition coils or wires and the battery terminal.
