Iridium Replacement Spark Plug for Nissan

STSP1074 is a Nissan-focused iridium spark plug range covering three OE references and two corresponding OEM references currently listed on this page. All listed products are identified with Iridium material, providing a consistent precious-metal spark plug category for aftermarket sourcing.

Two of the listed OE references correspond to the same OEM reference, while the remaining OE reference is matched with a different OEM number. For distributors and importers, each required item should therefore be confirmed according to the OE and OEM relationship already shown in the product list.

Grouping these references under STSP1074 can simplify Nissan spark plug sourcing, while reference-based identification helps keep individual purchasing requirements clear for repeat and mixed-model orders.

Iridium Electrode Material and Wear Resistance

Spark plug electrodes operate under repeated high-voltage discharge, combustion heat and rapid temperature changes. Iridium is commonly used in spark plug electrode designs because of its resistance to wear under these operating conditions.

As ignition cycles accumulate, the firing surfaces gradually wear and the effective spark gap can change. A larger gap generally requires a higher discharge voltage, so controlling electrode wear helps maintain a more consistent firing condition during normal operation.

Iridium material alone does not determine compatibility. Correct replacement should still follow the specified OE/OEM reference and complete spark plug requirements rather than material description or external appearance alone.

Purchasing Details for Bulk Orders

IGNX supplies STSP1074 for distributors, importers and automotive aftermarket brands. For wholesale or repeat purchasing, buyers should confirm each required spark plug according to the OE No. and corresponding OEM No. already listed on this page.

For quotation, buyers can submit the required OE or OEM reference from the list above together with order quantity, packaging requirements and any private-label information. For repeat or mixed-reference orders, confirming the complete purchasing list before production helps keep product specifications and order records consistent.
