Z6S113320 Iridium Platinum Ignition Spark Plug

STSP1050 is organized as a multi-reference ignition spark plug range covering three OE and OEM combinations currently listed for BMW and Mercedes-Benz applications. All listed items are identified with an Iridium & Platinum material configuration, providing a consistent precious-metal spark plug category for aftermarket sourcing.

Although the three products share the same IGNX number and material category, each corresponds to its own OE and OEM reference. Buyers should therefore confirm the required spark plug according to the matching reference already shown in the product list rather than treating the listed items as interchangeable.

For distributors and importers managing several ignition SKUs, grouping these references under STSP1050 makes sourcing more convenient while keeping each purchasing requirement clearly identified for quotation, inventory management and repeat orders.

Precious-Metal Electrode Design and Wear Control

Spark plug firing surfaces operate under repeated electrical discharge, combustion heat and rapid temperature changes. Iridium and platinum are widely used in precious-metal spark plug designs because they provide good resistance to electrode wear under these operating conditions.

Fine precious-metal firing surfaces can help concentrate the electric field around the firing area, while resistance to erosion helps limit gradual changes in electrode geometry as ignition cycles accumulate.

The Iridium & Platinum material category does not mean that every reference has an identical electrode structure or application specification. Correct replacement should continue to follow the OE and OEM relationship listed for each product rather than material description or external appearance alone.

Purchasing Details for Bulk Orders

IGNX supplies STSP1050 for distributors, importers and automotive aftermarket brands. For wholesale, mixed-reference or repeat purchasing, buyers should confirm each required spark plug according to the OE No. and corresponding OEM No. already provided in the product list.

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 product specifications and purchasing records consistent.
