A-Premium Iridium Platinum Spark Plugs Pack of 6 for V6 Engines — Fine Wire, OEM Fitment

A-Premium Iridium Platinum Spark Plugs pack of 6 are fine-wire replacement plugs engineered for V6 engines to deliver reliable ignition, long service life, and precise gap consistency.

These spark plugs combine an iridium-tipped center electrode with a platinum core to improve ignition stability and extend service intervals compared with conventional plugs. They are produced to match OEM fitment and specifications, making them suitable for several Acura, Honda and Jeep Grand Cherokee V6 models. The plugs come with a 5/8" hex, 14 mm thread diameter, 19.05 mm reach and a factory-set 0.044" gap for easy installation and dependable performance.

Will these plugs fit my vehicle's V6 engine?

Compatibility is intended for specific V6 engines from Acura, Honda and Jeep, following the referenced OE part numbers. Confirm your engine year and emission specification (e.g., non-SULEV for some Honda models) before ordering to ensure correct fit.

• Fits Acura MDX 2007–2009 V6 3.7L, RL 2005–2008 V6 3.5L, TL 2004–2008 V6 3.2L and TL 2007–2008 V6 3.5L.
• Fits Honda Accord 2003–2007 V6 3.0L (non-SULEV models only).
• Compatible with certain Grand Cherokee spark plug applications—verify OEM reference numbers: 6994, IZFR6K-11, XP5224, XS5224, IZFR6K11, 9807B5617W, 9807B5617WA0.

How do these spark plugs improve ignition and drivability?

The iridium tip promotes a concentrated, consistent spark while the platinum core supports thermal stability and wear resistance. That combination helps maintain reliable combustion over many miles, which can lead to smoother starts and steadier throttle response compared with worn or standard plugs.

• Iridium center electrode for focused spark and improved ignitability.
• Platinum core to resist electrode erosion and preserve gap size.
• 5000 ohm resistance for radio-frequency interference suppression.

What are the key specifications I need to know before installation?

These plugs are built to concrete dimensions so they thread, seat, and fire like the OEM parts. Confirm your engine’s required reach, thread diameter, hex size and insulator height to prevent installation issues and ensure safe operation.

• Gap: 0.044" (factory pre-set).
• Reach: 19.05 mm; Thread diameter: 14 mm; Hex size: 5/8".
• Insulator height: 50.50 mm; Resistance: 5000 ohms.

How long will these iridium platinum plugs last and when should I replace them?

Iridium/platinum plugs are designed for extended service life compared with conventional copper plugs and are typically replaced far less often. For optimal performance and to avoid misfires or loss of efficiency, follow recommended replacement intervals based on driving conditions and manufacturer guidance.

• Recommended replacement interval: approximately 80,000–100,000 miles under normal conditions.
• Check gap and inspect for fouling during regular maintenance intervals.
• Replace earlier if experiencing persistent misfires, rough idle, or poor fuel economy.

Who is this for? A-Premium Iridium Platinum Spark Plugs pack of 6 is aimed at vehicle owners and technicians who need an OEM-style fine-wire replacement for V6 engines used in select Acura, Honda and Jeep Grand Cherokee models. Choose this set if you want plugs that match OEM dimensions, offer long service life, and help maintain consistent ignition performance during routine maintenance or full tune-ups.
