STSP1051 is a Mercedes-Benz-focused replacement spark plug range covering five OE references and four corresponding OEM references currently listed on this page. All listed items are identified with an Iridium & Platinum material configuration, providing a consistent precious-metal spark plug category for aftermarket sourcing.
Some OE references within the range share the same OEM reference, while others correspond to different spark plug specifications. For distributors and importers, the required product should therefore be confirmed according to the OE No. and corresponding OEM No. shown in the product list rather than by product appearance alone.
Grouping these related references under STSP1051 makes it easier to manage Mercedes-Benz spark plug sourcing while keeping the individual purchasing requirement clearly identified for quotation, inventory and repeat orders.
5 Listed OE References Five Mercedes-Benz OE references are currently included within the STSP1051 range.
Iridium & Platinum All current entries are identified with the same precious-metal material category.
Reference-Based Selection Buyers should confirm each product using the corresponding OE and OEM information already listed on the page.
Iridium Platinum Electrode Design
Iridium and platinum are used in precious-metal spark plug designs to address the electrical discharge, combustion heat and repeated thermal cycling experienced at the firing end during engine operation.
In relevant iridium-platinum designs, a fine iridium center firing tip helps concentrate the electric field around the electrode, while platinum at the opposing firing surface provides resistance to repeated spark erosion. Together, these materials help control progressive wear at the firing gap.
Precious-metal construction does not make different spark plugs automatically interchangeable. Electrode design and other specifications can vary between references, so correct replacement should continue to follow the OE and OEM relationship specified for each item on this page.

IGNX supplies STSP1051 for distributors, importers and automotive aftermarket brands. For wholesale 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.
