STSP1064 is a Hyundai-focused ignition spark plug built around the single OE and OEM reference combination currently listed on this page. The product is identified with Iridium material, providing a clearly defined precious-metal spark plug reference for aftermarket distributors, importers and automotive parts buyers.
The current product information matches OE No. 18840-11051 with OEM No. ILFR5B-11. Because this page represents one specific reference rather than a multi-model product group, buyers can use this OE/OEM relationship directly when preparing quotations, purchasing lists and repeat orders.
Product selection should remain reference-based. Other iridium spark plugs may have similar external appearance but different firing-end or application specifications, so electrode material alone should not be used to determine interchangeability.
Laser Iridium Firing Design and Electrode Wear Control
ILFR5B-11 is classified within the Laser Iridium spark plug range. Iridium is suited to spark plug firing electrodes because it provides strong resistance to wear under repeated high-voltage discharge, combustion heat and rapid temperature changes.
Fine iridium firing-electrode designs can concentrate the electric field around the firing area, helping spark discharge occur efficiently. At the same time, resistance to electrode erosion helps limit gradual changes to the firing surface as ignition cycles accumulate.
Electrode condition is only one part of correct spark plug matching. STSP1064 should continue to be selected according to the 18840-11051 and ILFR5B-11 reference relationship shown on this page rather than by the term “Iridium” alone.
Purchasing Details for Bulk Orders
