Comparison Short Insights

When evaluating the Best Spark Plugs For Mitsubishi Lancer, the primary choice often comes down to material and whether you need a complete ignition kit.

If longevity and performance are your top priority, Iridium plugs like the NGK Iridium IX are the clear winner, offering superior lifespan and resistance to high heat. They require less maintenance and provide excellent, consistent spark.

For those on a tighter budget or prioritizing fuel economy, the DENSO Platinum TT plugs offer genuine OEM quality with an advanced twin-tip design that drastically improves spark efficiency without the cost of premium Iridium. This is a highly recommended choice for standard maintenance.

A key consideration for older Lancers is the condition of the ignition coils. Kits from brands like ECCPP and MOAUTO that include both coils and Iridium plugs are an incredibly high-value proposition. They ensure that potential misfires caused by weak coils are eliminated at the same time as you install your new, long-lasting plugs.

Finally, always confirm your engine type. Plugs designed for the Naturally Aspirated (NA) Lancer may have different heat ranges and gap requirements than those for the Lancer Evolution (Turbo) models—though most reviewed here are optimized for the standard Lancer L4 engines.

FAQ on Choosing the Best Spark Plugs for Mitsubishi Lancer

Q1: How often should I replace the spark plugs in my Mitsubishi Lancer?

The replacement interval depends heavily on the spark plug material. Standard nickel or copper plugs usually need replacing every 20,000 to 30,000 miles. However, if you upgrade to Iridium or Platinum spark plugs, which are recommended for the Lancer, the lifespan is significantly longer—often 60,000 to 100,000 miles. Always check your Lancer’s owner manual or the specific plug manufacturer’s guidelines.

Q2: What are the main differences between Iridium and Platinum spark plugs for the Lancer?

Iridium is generally considered the premium, longest-lasting material. It has a higher melting point than Platinum, allowing for a finer center electrode tip that provides a more consistent, powerful spark over a longer period. Platinum plugs, like the DENSO TT, offer excellent durability and performance, often better than standard plugs, but typically won’t match the extreme longevity of Iridium.

Q3: Do I need to gap my new spark plugs before installing them in my Lancer?

Most high-quality Iridium and Platinum spark plugs are pre-gapped from the factory for common applications, especially if they are direct OEM replacements. However, it’s always a good practice to double-check the gap against your specific Lancer engine’s required specification, as the gap can sometimes change during shipping. Never try to adjust the gap on fine-wire Iridium plugs drastically, as you might damage the tip.

Q4: How do I know if my Mitsubishi Lancer needs new spark plugs or ignition coils?

The symptoms of failing spark plugs and ignition coils are very similar and often overlap. Common signs include engine misfires (feeling a hesitation or jerk), rough idling, decreased power during acceleration, and a sudden drop in fuel efficiency. If your Check Engine Light (CEL) is flashing, it often indicates a severe misfire requiring immediate attention to the ignition system.

Q5: Is it better to buy a kit that includes both ignition coils and spark plugs?

Yes, for Lancer models approaching or exceeding 80,000 miles, replacing both components is highly recommended. Ignition coils degrade over time, losing voltage output, which can cause new spark plugs to wear out faster or perform poorly. Buying a combined kit ensures optimal ignition performance and streamlines your maintenance process.

Q6: Can I use performance spark plugs (like NGK Iridium) in a completely stock Lancer engine?

Absolutely. Performance spark plugs, particularly high-quality Iridium options, are excellent upgrades for any stock Lancer. They offer improved ignition reliability, better resistance to fouling, and extended service life compared to standard copper plugs, directly contributing to smoother running and better engine performance.
