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

A-Premium Iridium Platinum Spark Plugs pack of 6 are high-performance fine-wire ignition plugs designed for V6 engines, offering durable iridium tips, platinum cores, and long service intervals for compatible Mercedes, Dodge Sprinter, Freightliner, Mitsubishi and select models.

If your vehicle requires reliable ignition with a long service life, these A-Premium spark plugs deliver a combination of iridium tip precision and platinum core stability. Sold as a set of six, they’re engineered to match V6 engine specifications and come with fine-wire electrodes and exact reach, hex, and gap dimensions to fit the listed applications. Below you’ll find concise answers to common buyer questions plus a clear list of specifications and practical fitment details.

Which vehicles and engines will these spark plugs fit?

These plugs are specified for a range of V6 gasoline engines from Mercedes-Benz, Dodge/Freightliner Sprinter models, and some Mitsubishi Outlander years. They match models and engine displacements documented in the compatibility list, but always cross-check OEM part numbers before purchase.

• Common fits: Mercedes C-, E-, CLK-, GLK-, ML-, R-, S- and SLK-series V6 models (2005–2013 ranges listed).
• Sprinter compatibility: Dodge/Freightliner Sprinter 2500 and 3500 V6 3.5L (2007–2008).
• Mitsubishi Outlander V6 3.0L fits for model years 2007–2013.
• Also referenced by OE numbers and crossfits: 93911, LKR7AIX, XP5702, 08040K9000, BY480LKR7A, SAB330NG1709.

What are the key specifications and why do they matter?

Critical dimensions and materials determine ignition performance and installation compatibility. These plugs use an iridium tip for a fine electrode that reduces required voltage and a platinum core for structural stability, with specific reach, thread, and gap to match factory requirements.

• Center electrode tip material: Iridium for precise spark and durability.
• Center electrode core: Platinum to stabilize electrode performance.
• Resistance: 5000 ohms to reduce radio interference while ensuring ignition control.
• Gap: 0.032 in; Reach: 26.5 mm; Thread diameter: 12.00 mm; Hex size: 5/8 in.

How long do these iridium-platinum plugs typically last?

Iridium and platinum alloys extend service intervals versus conventional copper plugs, reducing maintenance frequency. A practical replacement guideline is listed mileage ranges, though actual life depends on driving style, engine condition, and tune.

• Recommended replacement interval: commonly 80,000–100,000 miles under normal driving conditions.
• Monitor for symptoms such as misfires, rough idle, or poor fuel economy as indicators to inspect sooner.
• Use correct torque and anti-seize practices at installation to protect threads and achieve proper sealing.

What should I check before installing these spark plugs?

Confirm fitment by comparing OEM part numbers and verifying engine specifications, gap, and thread reach. Proper installation technique ensures optimal performance and avoids engine damage.

• Verify the plug reaches and thread diameter match your engine’s cylinder head specifications.
• Confirm the 0.032 in gap suits your vehicle’s ignition system; adjust only if the manufacturer permits.
• Use a torque wrench to the vehicle maker’s torque spec to prevent over- or under-tightening.

Who is this for: The A-Premium Iridium Platinum Pack of 6 is aimed at owners and technicians working on V6 Mercedes-Benz models (mid‑2000s to early‑2010s), Dodge/Freightliner Sprinter V6 3.5L trucks, and specified Mitsubishi Outlander engines who want a longer-lasting, fine-wire ignition plug that matches factory dimensions. It’s a good choice for routine maintenance, tune-ups, or when restoring ignition reliability while keeping to OE-style fitment and service intervals.
