STSP1017 is a focused Nissan automotive spark plug product built around the single OE and OEM reference combination currently listed on this page. The product is identified by IGNX within the Double Iridium material category, providing distributors and importers with a clearly defined reference for aftermarket purchasing.
Because this page is based on one specific reference rather than a broad multi-model group, buyers can confirm the required product directly against the OE No. and OEM No. already provided in the product information.
Product selection should remain reference-based. Precious-metal spark plugs with similar appearance can differ in electrode construction and other application requirements, so material description alone should not be used to determine interchangeability.
Precious-Metal Electrode Design and Wear Control
Spark plug firing surfaces operate under repeated high-voltage discharge, combustion heat and rapid temperature changes. Precious-metal electrode designs are used to improve resistance to wear under these demanding operating conditions.
Iridium is commonly used in fine firing-electrode designs because its material properties allow a relatively small firing tip where required by the spark plug specification. A finer electrode can concentrate the electric field and reduce the voltage required to initiate spark discharge.
As electrode surfaces gradually wear, the firing geometry and effective spark gap can change. Controlling this wear helps maintain a more consistent firing condition during normal operation. Correct replacement, however, still depends on matching the specified OE/OEM reference rather than electrode material alone.
Purchasing Details for Bulk Orders
IGNX supplies STSP1017 for distributors, importers and automotive aftermarket brands. For wholesale and repeat purchasing, buyers can confirm the required product according to the OE No. and corresponding OEM No. already listed on this page.
For quotation, buyers can provide the OE or OEM reference listed above together with the required quantity, packaging requirements and any private-label information. Confirming the product reference and order requirements before production helps simplify repeat purchasing and inventory management.
