STSP1088 is a Hyundai-focused automotive spark plug supplied against two OE references currently listed on this page. Both OE numbers correspond to the same SILZKR7B-11 OEM reference and are identified with an Iridium & Platinum material configuration.
This reference structure gives distributors and importers a clear basis for aftermarket purchasing. Buyers can identify the required product according to either OE No. shown in the product list and confirm it against the corresponding SILZKR7B-11 reference before quotation or order placement.
Even when two OE references share the same OEM number and electrode material category, purchasing should remain reference-based. Product identification through the listed OE/OEM relationship helps reduce confusion when several similar spark plug SKUs are managed together.
2 Listed OE References Two Hyundai OE references are currently included within the STSP1088 product range.
Common OEM Reference Both listed OE numbers correspond to SILZKR7B-11 in the current product information.
Iridium & Platinum Both entries are identified within the same precious-metal material category.
Iridium Center Electrode with Platinum Ground Surface
The SILZKR7B-11 specification uses a precious-metal firing design with an iridium center electrode and a platinum firing surface on the ground electrode. These materials are used at the spark gap to withstand repeated electrical discharge and combustion heat during normal engine operation.
The fine iridium center firing tip helps concentrate the electric field around the electrode, supporting efficient spark discharge. Platinum on the ground-electrode firing surface helps resist repeated spark erosion and limits progressive wear at the firing gap.
These electrode characteristics are part of the specific SILZKR7B-11 design and should not be used to assume that other iridium-platinum spark plugs are interchangeable. Correct replacement should continue to follow the OE and OEM references listed for STSP1088.
