AGSF24N Iridium Platinum Engine Spark Plug

STSP1054 is a multi-reference engine spark plug range covering two OE references and three corresponding OEM references currently listed on this page. The range includes BMW and Land Rover applications, allowing aftermarket distributors and importers to manage several related spark plug requirements within one sourcing group.

The BMW OE reference is currently matched with two different OEM spark plug references, while the Land Rover OE reference corresponds to AGSF24N. Because these products do not necessarily share the same electrode construction, each required item should be confirmed according to the OE No., OEM No. and material information shown in the product list.

This grouped structure can simplify quotation and inventory management, but the individual references should remain separately identified rather than being treated as interchangeable products based only on the page title or external appearance.

Reference-Specific Precious-Metal Electrode Designs

Precious-metal spark plug designs use materials such as iridium and platinum at the firing surfaces to improve resistance to electrode wear under repeated electrical discharge and combustion heat.

However, the exact electrode configuration can differ between the OEM references grouped under STSP1054. Some specifications use iridium-based precious-metal designs, while others use platinum-based firing surfaces. These differences form part of the individual spark plug specification and should be retained when selecting a replacement.

For this reason, electrode material should be checked together with the corresponding OE/OEM reference. A similar precious-metal description does not mean that different spark plugs have the same firing-end construction or can be used interchangeably.

Purchasing Details for Bulk Orders

IGNX supplies STSP1054 for distributors, importers and automotive aftermarket brands. For bulk, mixed-reference or repeat purchasing, buyers should confirm each required spark plug according to the OE No. and corresponding OEM No. already listed on this page.

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.
