PFR6G11 Iridium Platinum Replacement Spark Plug

STSP1029 is organized as a multi-reference replacement spark plug range covering four OE and OEM combinations currently listed for Toyota, Nissan and Mitsubishi applications. This allows aftermarket distributors and importers to manage several related ignition references within one sourcing group.

The current product list identifies Iridium & Platinum together with Iridium in the material fields. Because the four entries correspond to different OE and OEM references, they should be treated as reference-specific products rather than assumed to have completely identical electrode construction.

For bulk purchasing, the corresponding OE No., OEM No. and material information shown in each row provide the clearest basis for product identification and order confirmation.

Precious-Metal Firing Surfaces and Electrode Wear

Spark plug electrodes operate under repeated electrical discharge, combustion heat and rapid temperature changes. Precious metals such as iridium and platinum are commonly used at spark plug firing surfaces because they offer good resistance to electrode wear under these operating conditions.

As firing surfaces gradually wear, electrode geometry and the effective spark gap can change. Controlling this wear helps maintain a more consistent firing condition during normal engine operation.

Electrode material is only one part of the complete spark plug specification. Different references grouped on this page may use different firing-end constructions, so compatibility should be confirmed according to the listed OE/OEM relationship rather than material description or external appearance alone.

Purchasing Details for Bulk Orders

IGNX supplies STSP1029 for distributors, importers and automotive aftermarket brands. For wholesale or repeat purchasing, buyers should confirm each required product according to the OE No., OEM No. and corresponding material information already listed on this page.

For quotation, buyers can submit the required 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.
