Iridium Tough Spark Plugs

Iridium Tough is Denso's premium OE and aftermarket spark plug product for performance and service life combined. Suitable for modern engines where ultimate performance is required and service intervals may be long. These plugs can last for up to 100,000 miles without a significant decrease in performance. If your engine bay is difficult to access or partial engine dismantling is required to change the plugs then Iridium Tough plugs are a great option.

Tough Plugs are designed using Denso's patented ultra fine Iridium alloy centre electrode which is matched to a ground electrode containing a platinum 'chip' to extend service life. Some extremely high specification designs even feature multiple ground electrodes. Materials used are of generally higher specification than standard plugs. Suitable for high performance engines, for ultimate service life without compromising on performance, and for liquified petroleum gas (LPG) converted engines.
