IRIDIUM POWER Spark Plugs

At Design911, we offer a dedicated range of IRIDIUM POWER spark plugs for Porsche models, giving you a high-quality ignition option that’s engineered for consistent performance and long service life.

Why do IRIDIUM POWER Spark Plugs matter?

Iridium plugs play a key role in how cleanly and reliably your Porsche engine ignites the air–fuel mixture. Compared with many conventional plugs, iridium designs use a very hard, fine centre electrode material that is intended to stay stable over a long period. This helps maintain a consistent spark, reduces the need for frequent plug changes and can support smooth running when everything is correctly matched to the engine specification.

Choosing the right IRIDIUM POWER spark plugs for your Porsche and keeping them in good condition helps the engine start reliably, run more cleanly and feel well maintained throughout the service interval.

• Support clean, reliable ignition when correctly specified and installed
• Help maintain smooth running and stable idle over a long service life
• Reduce the frequency of plug changes compared with many standard types
• Allow you to choose reputable brands matched to Porsche engine requirements

When should you review or replace your Porsche iridium power spark plugs?

Checking the condition and service history of your IRIDIUM POWER spark plugs is an important part of looking after any Porsche engine. Even durable iridium designs can eventually wear, foul or become less effective if they are past the recommended interval or not correctly matched to the engine.

• You experience misfires under load, hesitation, rough idle or harder starting
• Fuel consumption has increased compared with typical usage for your Porsche
• The current plugs have exceeded the service interval suggested in the owner’s manual

If any of these apply, it is a good time to review your IRIDIUM POWER spark plugs and replace anything that is past its best so your Porsche remains dependable and enjoyable to drive.
