| The table below lists some common NGK standard copper and platinum spark plug types and their closest Iridium IX equivalent parts. Please be aware that equivalents are not always identical in design, for example all Iridium IX plugs have only a single ground electrode whereas your original may have multiple grounds. You should ensure that an Iridium equivalent will be a suitable fit and heat range for your application before making a purchase or attempting to fit. You should also be aware that all Iridium plugs have an internal 5 K Ohm resistor, your original parts may be non resistorised (non supressed), in which case only trial and error will decide whether you can use an Iridium (i.e. resistorised) part. |
| This list is provided, without warranty, for your information. Use the information at your own discretion and always exercise extreme caution when using an alternative to the manufacturer's standard plug recommendation. |
| This by no means an exhaustive list, if your standard part number does not appear in this list it does not necessarily follow that there is no Iridium IX equivalent. Please use the partsearch on our homepage to check for equivalent plugs to your standard part. Contact us if you need further assistance. |
