STSP1045 is a BMW-focused engine spark plug range covering two OE references and three corresponding OEM references currently listed on this page. One OE reference corresponds to LZFR6AP11GS, while the other is listed with both PLZFR6A-11S and FR7NPP332, giving distributors and importers several reference-specific options within one sourcing group.
The listed OEM references do not use an identical precious-metal electrode configuration. Their specifications include both single-precious-metal platinum and double-platinum designs, so each required product should be confirmed according to the corresponding OE No. and OEM No. rather than treated as one uniform electrode type.
For wholesale sourcing, grouping these BMW references under STSP1045 can simplify quotation and inventory management, while keeping the individual spark plug specification clearly identified for purchasing and repeat orders.
Reference-Specific Platinum Electrode Designs
The OEM references grouped under STSP1045 use different platinum electrode configurations. LZFR6AP11GS belongs to a single-precious-metal platinum type, while PLZFR6A-11S and FR7NPP332 use double-platinum firing designs.
Platinum is used at spark plug firing surfaces because it provides good resistance to electrode erosion under repeated electrical discharge and combustion heat. In double-platinum designs, precious-metal firing surfaces are used on both sides of the spark gap to help control wear as ignition cycles accumulate.
These differences form part of the individual spark plug specification. A single-platinum and a double-platinum spark plug should not be treated as interchangeable simply because they are grouped on the same page or share a similar external appearance.
Purchasing Details for Bulk Orders
IGNX supplies STSP1045 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 reference from the list above together with order quantity, packaging requirements and any private-label information. For mixed-reference orders, confirming the complete purchasing list before production helps reduce specification confusion and simplifies repeat purchasing.
