Double Iridium Auto Spark Plug for Nissan

STSP1016 is a Nissan-focused spark plug range covering two OE and OEM combinations currently listed on this page. Both entries are grouped within the Double Iridium / Iridium material category, providing distributors and importers with a focused range for the corresponding Nissan ignition references.

Although the two products share the same IGNX product number and precious-metal category, each corresponds to its own OE and OEM reference. Buyers should therefore confirm the required item according to the matching reference shown in the product list rather than treating the two entries as interchangeable.

For aftermarket sourcing, this reference-based structure makes it easier to manage related Nissan spark plug requirements while keeping each purchasing specification clearly identified.

Precious-Metal Electrode Design and Ignition Stability

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

In appropriate spark plug designs, iridium also allows a relatively fine center firing electrode. A finer firing tip concentrates the electric field around the electrode and can reduce the voltage required to initiate spark discharge.

Electrode material is only one part of the complete spark plug specification. As the firing surfaces wear, electrode geometry and the effective gap can change, so correct replacement should still follow the required OE/OEM reference and overall product configuration rather than material description alone.

Purchasing Details for Bulk Orders

IGNX supplies STSP1016 for distributors, importers and automotive aftermarket brands. For wholesale and repeat purchasing, buyers should confirm each required spark plug according to the OE No. and corresponding OEM No. already provided in the product list.

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 orders, confirming the complete purchasing information before production helps keep product specifications and order records consistent.
