STSP1091 is an Iridium & Platinum automotive spark plug supplied against two OE references currently listed on this page. Both OE numbers correspond to the same SILZKAR8G7Y OEM reference, giving distributors and importers a clearly defined product for aftermarket replacement purchasing.
The two OE references are grouped under one IGNX product number because they share the same corresponding OEM spark plug reference and material category. Buyers can therefore use the OE/OEM relationship already shown in the product list as the primary basis for product identification and quotation.
Even within the Iridium & Platinum category, replacement should remain reference-based. Similar precious-metal spark plugs may differ in firing-end design or other specifications, so external appearance alone should not be used to determine interchangeability.
2 Listed OE References JDE38685 and LR091617 are both currently listed under the STSP1091 product range.
Common OEM Reference Both listed OE numbers correspond to SILZKAR8G7Y on the current product page.
Iridium & Platinum The current IGNX product information identifies both entries within the same precious-metal category.
Fine Iridium Center Electrode with Platinum Ground Surface
The SILZKAR8G7Y specification belongs to a Laser Iridium precious-metal spark plug design. A fine iridium center firing electrode helps concentrate the electric field around the firing tip, supporting efficient spark discharge during ignition.
Platinum is used at the ground-electrode firing surface to improve resistance to repeated spark erosion. The combination of fine-electrode geometry and wear-resistant precious metals helps limit progressive changes to the firing surfaces as ignition cycles accumulate.
These electrode characteristics are part of the specific spark plug design and should not be treated as a universal upgrade for other applications. Correct replacement should continue to follow the OE and OEM references specified for STSP1091.
