Iridium Automotive Spark Plug FR5EI

STSP1006 is organized as a multi-reference automotive spark plug range rather than a single-reference product. The current product list includes seven OE/OEM combinations for Mitsubishi and Volvo applications, allowing aftermarket buyers to source several related ignition references within one product group.

Iridium is shown across the listed references, while several Mitsubishi entries also include Nickel-copper information in the material fields. Because the page contains different OE/OEM combinations and material information, each required item should be confirmed against its corresponding row before ordering.

For distributors and importers managing multiple spark plug SKUs, this grouped structure can simplify sourcing, while the individual OE No., OEM No. and material information remain the basis for identifying the required product.

Iridium Electrode Material and Wear Resistance

Spark plug firing surfaces operate under repeated electrical discharge, high combustion temperatures and continuous heating and cooling cycles. Iridium is commonly used in spark plug electrodes because of its resistance to wear under these demanding operating conditions.

Electrode condition gradually changes as spark discharge accumulates. When the firing surfaces wear and the effective spark gap increases, a higher voltage may be required to produce the spark. Using a wear-resistant electrode material helps reduce this progression and maintain a more consistent firing condition during normal use.

Material alone does not determine whether a spark plug is suitable for a particular application. The required product should still be selected according to the OE/OEM reference and corresponding specification already provided in the product list.

Purchasing Details for Bulk Orders

IGNX supplies this spark plug range for distributors, importers and automotive aftermarket brands. For STSP1006, buyers should confirm each required item according to the OE No., OEM No. and material information already listed on this page before quotation or production.

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 repeat or mixed-reference orders, confirming the complete purchasing list before production helps keep product specifications and order records consistent.
