Double Iridium Ignition Spark Plug DILKAR7B8

STSP1019 is organized as a multi-reference Double Iridium spark plug range covering six OE/OEM combinations currently listed for Toyota, Nissan and Mazda applications. All entries on this page are classified under the same Double Iridium material category, providing a focused precious-metal spark plug range for aftermarket sourcing.

Although these references are grouped under one IGNX product number, they correspond to different OE and OEM requirements. Each item should therefore be selected according to the matching reference shown in the product list rather than assuming that all listed products are directly interchangeable.

For distributors and importers purchasing several ignition SKUs, this grouped structure provides a convenient way to manage related spark plug references while keeping the individual purchasing specification clearly identified.

Precious-Metal Electrode Design for Wear Control

Spark plug firing surfaces operate under repeated electrical discharge, combustion heat and rapid temperature changes. Iridium-based precious-metal electrode designs are used because iridium provides strong resistance to wear under these operating conditions.

Electrode wear gradually changes the condition of the firing surfaces and can affect the effective spark gap. Limiting this wear helps maintain a more stable electrode condition as ignition cycles accumulate.

Material type is only one part of the spark plug specification. Correct replacement still depends on the required OE/OEM reference and complete product configuration, so a similar-looking iridium spark plug should not automatically be treated as an equivalent substitute.

Purchasing Details for Bulk Orders

IGNX supplies STSP1019 for distributors, importers and automotive aftermarket brands. For wholesale and repeat orders, buyers should confirm each required product according to the OE No. and corresponding OEM No. already listed on this page.

For quotation, buyers can submit the required OE or OEM references from the list above together with order quantities, packaging requirements and any private-label information. For mixed-reference or repeat orders, confirming the complete purchasing list before production helps keep specifications and order records consistent.
