How do ENA’s iridium-platinum electrodes benefit engine performance?

The iridium center tip and platinum ground electrode provide a harder, wear-resistant spark surface than conventional nickel plugs, which helps maintain consistent ignition over extended intervals. That stability supports smoother starts and steadier combustion as electrode wear is reduced.

• Iridium tip offers fine-point spark focus for reliable ignition
• Platinum ground reduces gap erosion for longer service life
• Pre-gapped to 0.039 in to match factory specifications
• Durable construction helps resist fouling and misfires under normal driving

The ENA 5018 spark plug is built to match the OEM thread and hex measurements so it can be installed with common tools. It ships as a set of 16, pre-gapped, and sized to suit V8 cylinder banks used in the listed vehicles—no custom modification required for a correct fit.

• Center electrode: iridium; ground electrode: platinum
• Gap: 0.039 in (pre-gapped at the factory)

Will these spark plugs replace my OEM part numbers?

ENA provides a comprehensive cross-reference to many OEM and aftermarket part numbers so you can match against the part already specified for your vehicle. The listing includes common references and alternative numbers to simplify verification before purchase.

• Cross-references include 5018, LFR5AGP and multiple OEM codes
