A-Premium Iridium Platinum Spark Plugs Pack of 6

A-Premium Iridium Platinum spark plugs pack of 6 is a direct-fit ignition component engineered for V6 engines that combines an iridium center tip with a platinum core to improve ignitability and long-term durability.

These spark plugs are built to meet OEM-style specifications for several V6 applications, including select Acura, Honda, and Jeep models. Each plug uses a fine-wire iridium tip and a platinum core to promote consistent sparks while offering extended service life under normal operating conditions. The pack includes six plugs with a 0.044 in gap, 14 mm thread diameter, 19.05 mm reach, and 5/8 in hex size—dimensions chosen for direct replacement in compatible engines.

How do these plugs improve starting and throttle response?

The iridium fine wire tip lowers the voltage required to fire the plug and produces a more focused spark, which helps the air/fuel mixture ignite more reliably. That can translate to crisper throttle response and steadier idle in compatible engines.

• Iridium center electrode for strong, concentrated sparks
• Platinum core for stable conduction and wear resistance
• 5000 ohm resistor to reduce radio-frequency interference
• 0.044 in gap pre-set for common V6 applications

What vehicles and engine types will these fit?

These A-Premium plugs are designed to replace factory parts on a range of V6 engines. The listing includes specific fits for Acura and Honda V6s, and they’re compatible with Grand Cherokee models that use the listed reference numbers. Always verify fitment against your vehicle’s year, engine code, and emissions configuration (SULEV vs non-SULEV) before purchasing.

• Acura MDX 2007–2009 V6 3.7L
• Acura RL 2005–2008 V6 3.5L
• Acura TL 2004–2008 V6 3.2L and 2007–2008 V6 3.5L
• Honda Accord 2003–2007 V6 3.0L (non-SULEV only)

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

Iridium and platinum combination plugs are made for extended service life compared with standard copper plugs. Under normal driving and maintenance, replacement is typically recommended in the 80,000–100,000 mile range, but driving conditions and engine health affect actual intervals.

• Iridium tip and platinum core for reduced electrode wear
• Recommended replacement: 80,000–100,000 miles under normal conditions
• Inspect earlier if misfires, rough idle, or ignition issues occur

What are the key specifications and installation details?

These plugs ship as a set of six and match common OEM dimensions to simplify installation. Torque and gap verification during installation ensure reliable operation; use a torque wrench and check gap only if necessary to maintain the specified 0.044 in spacing.

• Pack quantity: 6 spark plugs, fine-wire iridium tip
• Gap: 0.044 in; hex size: 5/8 in; reach: 19.05 mm; insulator height: 50.50 mm
• Thread diameter: 14 mm; resistance: 5000 ohms for EMI suppression
• Reference numbers include IZFR6K-11, XP5224, XS5224 and others for cross-checking

Who is this for: These A-Premium Iridium Platinum spark plugs are ideal for owners and mechanics who need a cost-effective, OEM-style replacement for V6 engines listed in the fitment notes. They suit drivers seeking longer service intervals and improved ignition consistency without modifying the ignition system, as well as DIYers who want clear, direct-fit specifications for routine maintenance or tune-ups.
