Mitsubishi 1822A011 Iridium Engine Spark Plug

STSP1068 is a Mitsubishi-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 Iridium material category, providing a clearly defined reference for aftermarket distributors, importers and ignition-parts buyers.

Because this is a single-reference product rather than a multi-model group, the required spark plug can be confirmed directly according to the OE No. and corresponding OEM No. already provided in the product information.

Reference matching remains important even when products share a similar precious-metal description. Spark plugs can differ in firing-end design and other application specifications, so material type or external appearance alone should not be used to determine interchangeability.

Precious-Metal Electrode Design and Wear Control

Spark plug firing surfaces operate directly in the combustion chamber and are repeatedly exposed to high-voltage discharge, combustion heat and rapid temperature changes. Precious-metal electrode designs are used to improve resistance to wear under these operating conditions.

Iridium is commonly used in fine firing-electrode designs because it can maintain a small working surface while resisting electrode erosion. A fine firing area also helps concentrate the electric field around the electrode, supporting efficient spark discharge.

As operating cycles accumulate, electrode wear can gradually change firing-surface geometry and the effective spark gap. Limiting this wear helps maintain a more consistent firing condition, but correct replacement still depends on matching the specified OE and OEM reference rather than electrode material alone.

Purchasing Details for Bulk Orders

IGNX supplies STSP1068 for distributors, importers and automotive aftermarket brands. For wholesale and repeat purchasing, buyers can confirm the required spark plug directly 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 reference and purchasing requirements before production helps simplify repeat ordering and inventory management.
