How often should NGK spark plugs be replaced?

Copper plugs typically last around 30,000 to 50,000 km, while NGK iridium and platinum plugs can last 100,000 km or more depending on your engine. Always follow your vehicle's maintenance schedule; our fitment results show the right plug for your application.

Do NGK spark plugs come pre-gapped?

Many NGK plugs ship pre-gapped to a common setting, but you should always verify the gap against your vehicle's specification before installing, especially on performance applications. Iridium plugs require careful gapping to protect the fine center electrode.
