Best Spark Plugs For 2013 Honda Accord: Frequently Asked Questions

What type of spark plugs does the 2013 Honda Accord 2.4L L4 use?

The 2013 Honda Accord 2.4L L4 engine is highly tuned and requires a premium spark plug. Honda originally equipped this engine with Iridium plugs. It is highly recommended to replace them with high-quality Iridium (or Double Iridium) plugs to maintain proper ignition timing, optimal fuel efficiency, and engine longevity.

How often should I change the spark plugs in my 2013 Accord?

For Iridium spark plugs, the general replacement interval recommended by Honda is often around 100,000 to 105,000 miles. However, if you experience performance issues such as rough idling, engine misfire, or noticeable hesitation upon acceleration, they should be inspected and potentially replaced sooner, regardless of the mileage.

Do I need to gap iridium spark plugs for my Honda Accord?

While most iridium spark plugs come pre-gapped from the factory, it is always crucial to verify the gap setting before installation. The correct gap for the 2013 Honda Accord 2.4L engine is typically around 1.0mm to 1.1mm (0.044 inches). Never use excessive force or a cheap gapping tool, as the fine-wire iridium tip can be easily damaged.

What are the main benefits of choosing Iridium over Platinum or Copper plugs?

Iridium offers superior benefits for the 2013 Accord compared to older plug materials. Iridium has a higher melting point than platinum or copper, allowing for a much finer center electrode. This fine electrode requires less voltage to fire and lasts significantly longer, leading to a much more consistent, reliable, and longer-lasting spark—up to four times the life of standard plugs.

Should I replace my ignition coils when I replace my spark plugs?

If your vehicle has high mileage (over 100k miles) or if you are specifically trying to diagnose a persistent rough engine idle or misfire, replacing the ignition coils (like the UF712 reference) along with the spark plugs is often advised. Coils degrade over time, and replacing them prevents future issues and ensures the new plugs receive the strongest possible voltage.

Will installing performance spark plugs increase the horsepower of my 2013 Honda Accord?

While upgrading from old, worn-out spark plugs to new, high-quality NGK or DENSO Iridium plugs will restore lost horsepower and engine smoothness, installing a “performance” plug in a stock engine typically won’t yield significant measurable horsepower increases. Their primary benefit is improved ignition stability, better throttle response, and more reliable starts.
