Honda Double Iridium Engine Spark Plug 12290-6A0-A01

STSP1022 is a Honda-focused engine spark plug 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 a clearly defined precious-metal spark plug reference for distributors, importers and automotive aftermarket buyers.

The current product information matches OE No. 12290-6A0-A01 with OEM No. DILKAR8P8SY. Because this is a single-reference product rather than a multi-model group, buyers can use this OE/OEM relationship directly when preparing quotations, purchase lists and repeat orders.

Reference-based selection remains important even among precious-metal spark plugs. Products with similar names or external appearance can differ in firing-end construction and other application specifications, so the listed OE/OEM relationship should remain the primary basis for replacement purchasing.

Precious-Metal Firing Design and Electrode Wear Control

The firing end of a spark plug operates 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.

Fine precious-metal firing surfaces can concentrate the electric field around the firing area, helping spark discharge occur efficiently. Resistance to electrode erosion also helps limit gradual changes to firing-surface geometry as ignition cycles accumulate.

The material category alone does not determine compatibility. STSP1022 should continue to be selected according to the 12290-6A0-A01 and DILKAR8P8SY reference relationship shown on this page rather than by the term “Double Iridium” or external appearance alone.

Purchasing Details for Bulk Orders

IGNX supplies STSP1022 for distributors, importers and automotive aftermarket brands. For wholesale and repeat purchasing, buyers can confirm the required product directly according to OE No. 12290-6A0-A01 and OEM No. DILKAR8P8SY already listed on this page.

For quotation, buyers can provide 12290-6A0-A01 or DILKAR8P8SY together with the required quantity, packaging requirements and any private-label information. Confirming the product reference and purchasing requirements before production helps simplify order checking, repeat purchasing and inventory management.
