How often do my Porsche 996’s spark plugs need to be replaced?

Changing your Porsche 996’s spark plugs is an important maintenance job, as allowing their condition to deteriorate can result in sluggish acceleration, misfires and problems starting the engine.

We recommend replacing your Porsche 996’s spark plugs before any performance issues arise.

Typically, this means changing them every 24,000 miles or 2 years for pre-MY2002 cars and every 48,000 miles or 4 years for later 996s. The work is usually carried out alongside a major service.
