• The Iridium TT is designed to last beyond 100,000 km.
• Less stock, same coverage: TT Plugs cover many applications with fewer part references.

This results in more complete combustion which is good for all types of driving - the engine starts easily, there are fewer misfiers, acceleration improves along with fuel economy.
