E46 Spark Plug change - How often??

[Over Clocker]

Hi guys,

Does anyone know the recommended mileage interval for spark plug change on an E46 320i (2.2 6pot)?

Cheers,

Mal

Every Inspection 2. This is condition space but generally around every 60,000 miles or, potentially in the case of low mileage drivers, 8 years.

Hmmm... Any benefit from changing them more often?

Also, is the "lifetime" gearbox oil really lifetime?

If they're rusted up or not sparking properly, it will have an impact on fuel economy. You won't know that without taking them out and checking their condition.

Isn't the gearbox sealed?

No, it's just a regular box.

That's quite normal when using platinum spark plugs....you do pay a bit extra though.

Mine were £35 iirc for the vrs. Every 10k on the 307 isn't excessive if you only use the copper ones (a lot cheaper but don't last as long).

Anyone ever used silver spark plugs?
