PK20R11 Platinum Ignition Spark Plug

STSP1005 is organized as a two-reference spark plug range covering the OE and OEM combinations currently listed on this page. The group includes precious-metal spark plug specifications for different replacement requirements, allowing distributors and importers to source the required reference under one IGNX product number.

The material information is not identical across the two listed items. The PK20R11 entry is identified as a platinum spark plug, while the other listed reference uses an iridium specification. Each item should therefore be selected according to the corresponding OE No., OEM No. and material information already shown in the product list.

For wholesale purchasing, this reference-based approach is more reliable than selecting a spark plug only by product title, precious-metal category or external appearance.

PK20R11 Platinum Electrode Construction

The PK20R11 specification uses platinum at both the center and ground electrode firing surfaces. Platinum is well suited to spark plug electrodes because it resists the electrical erosion and high-temperature wear produced by repeated ignition cycles.

During normal engine operation, every spark gradually affects the firing surfaces. As electrode wear progresses, the shape of the electrodes and the effective spark gap can change. Using platinum at the working surfaces helps reduce this wear and maintain a more consistent electrode condition over time.

Precious-metal material is only one part of spark plug selection. Correct replacement should still follow the specified OE/OEM reference and corresponding product information rather than assuming that different platinum or iridium spark plugs are interchangeable.

Purchasing Details for Bulk Orders

IGNX supplies STSP1005 for distributors, importers and automotive aftermarket brands. Because this page contains two references with different material specifications, buyers should confirm the required item against the OE No., OEM No. and material information already listed above before quotation or production.

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 repeat or mixed-reference orders, confirming the complete purchasing list before production helps keep specifications and order records consistent.
