A-Premium Iridium Platinum Spark Plugs Pack of 6 — Fine-Wire V6 Replacement, Long Life

A-Premium Iridium Platinum spark plugs (pack of 6) are fine-wire, V6-compatible plugs engineered with an iridium tip and platinum core for reliable ignition and extended service life.

These replacement spark plugs are built to factory-alignment specifications for many V6 engines, including specific Honda and Acura models and certain Jeep/Grand Cherokee applications. They combine an iridium center electrode with a platinum core and a recommended replacement interval up to 80,000–100,000 miles, offering a balance of consistent ignitability and long wear life. Below you’ll find clear answers about fit, performance, and installation considerations so you can decide if these are the right plugs for your vehicle.

What engines and part numbers do these A-Premium spark plugs fit?

These plugs are compatible with a range of V6 engines and match multiple reference numbers used by OEM and aftermarket catalogs. Consult your vehicle’s service manual or the parts list below to confirm fitment before ordering.

• Reference numbers: 6994, IZFR6K-11, XP5224, XS5224, IZFR6K11, 9807B5617W, 9807B5617WA0
• Compatible vehicles: Acura MDX (2007–2009) 3.7L V6, Acura RL (2005–2008) 3.5L V6, Acura TL (2004–2008) 3.2L & (2007–2008) 3.5L V6
• Honda Accord fitment: 2003–2007 V6 3.0L (non-SULEV models only)

How are these plugs built and what performance should I expect?

The plugs use an iridium tip for the center electrode and a platinum core, materials selected for high durability and steady spark delivery. You can expect consistent ignition characteristics across normal driving conditions and a long service life when installed and gapped correctly.

• Center electrode tip: iridium for strong spark resilience
• Core material: platinum to resist erosion and wear
• Resistance: 5000 ohms for EMI suppression and ignition stability
• Gap: factory-set to 0.044 in for correct spark distance

What are the exact specifications and installation dimensions?

Knowing the physical dimensions helps ensure compatibility with your engine’s cylinder head and ignition components. These measurements match many OEM replacement specifications used on the listed V6 engines.

• Thread diameter: 14 mm
• Reach: 19.05 mm (3/4 in approx.) to seat correctly in the cylinder head
• Hex size: 5/8 in for socket and wrench selection
• Insulator height: 50.50 mm for proper clearance with coil boots

When should these spark plugs be replaced and what maintenance matters?

Iridium and platinum electrodes extend service intervals compared with standard plugs, but replacement timing depends on driving habits and engine condition. Follow recommended mileage intervals and inspect plugs for fouling or damage during routine tune-ups.

• Suggested replacement interval: 80,000–100,000 miles under normal use
• Check for oil, carbon buildup, or physical damage during service
• Use the specified 0.044 in gap and torque to factory specs at installation
• Avoid SULEV-equipped engines unless explicitly listed as compatible

Who is this for: These A-Premium Iridium Platinum spark plugs are aimed at owners and technicians who need OEM-aligned replacement plugs for V6 vehicles such as Acura MDX, RL, TL and select Honda Accord models (non-SULEV). They suit drivers who prioritize long-life electrodes and consistent ignition performance without frequent replacements, as well as DIY mechanics seeking clear specifications for confident installation.
