Comparison Short Insights

When looking at the Best Spark Plugs For 2013 Ford Focus, you’re generally choosing between standalone premium plugs and comprehensive plug/coil kits.

For pure spark plug performance, NGK Iridium IX stands out for responsiveness and brand trust, though its replacement interval is shorter than the Iridium Platinum options. If you want maximum time between changes, look at the Double Iridium kits (like those from KacuYelin or the LTR6BHX kit), which boast lifespans approaching 100,000 miles.

If your Focus is experiencing misfires or has over 80,000 miles, purchasing a combo kit is highly recommended. The ECCPP and TAUTOY UF670 kits offer fantastic value by bundling new ignition coils along with iridium plugs, ensuring that the entire ignition system is refreshed.

Remember to always verify the required gap for your specific 2013 Focus engine (especially if you have the ST model or a non-standard tune), as we noted small variations, such as the A-Premium 0.032 inch versus the A-Premium 0.036 inch options. For most standard 2.0L naturally aspirated engines, the OEM specification should be followed closely.

Final Verdict

Choosing the right components for your 2013 Ford Focus boils down to your vehicle’s current condition and your budget.

If you need the absolute longest service life and the best spark technology available, the UF670 Ignition Coil Pack and Double Iridium Spark Plugs Set of 4 (KacuYelin) is your top-tier choice. The 100,000+ mile potential is hard to beat.

For premium, standalone spark plug replacement, without changing the coils, we highly recommend the 4 pc NGK Iridium IX Spark Plugs. They offer proven performance gains and superior throttle response, making your Focus feel sharp again.

Best Spark Plugs For 2013 Ford Focus: Frequently Asked Questions

Q: What is the recommended spark plug change interval for a 2013 Ford Focus?

A: For the 2013 Ford Focus 2.0L engine, the factory-recommended interval is typically around 60,000 to 100,000 miles, depending on whether you are using traditional Platinum or high-end Iridium spark plugs. However, if you notice poor engine performance, hesitation, or decreased fuel efficiency, you should inspect and replace them sooner.

Q: Should I choose Iridium or Platinum plugs for my 2013 Focus?

A: Iridium spark plugs are generally superior and are recommended for modern Ford engines. Iridium is harder and has a higher melting point than platinum, allowing for a finer center electrode tip. This results in a more concentrated, reliable spark, leading to better cold starts, smoother idle, and optimal engine performance.

Q: Do I need to gap my new spark plugs before installing them in my Focus?

A: Even if a spark plug is labeled “pre-gapped,” it’s always best practice to check the gap size against the manufacturer’s OEM specification using a quality wire gauge tool. Shipping can sometimes slightly alter the gap. For the standard 2013 Focus 2.0L, the factory gap is usually 0.032 inches, though always confirm with your owner’s manual.

Q: What are the symptoms of bad spark plugs in a 2013 Ford Focus?

A: Common symptoms indicating worn or faulty spark plugs include a rough engine idle, noticeable engine misfires (especially under acceleration), difficulty starting the car, poor acceleration, and a significant drop in gas mileage. If the plugs are severely fouled, you might also trigger the Check Engine Light (CEL).

Q: If I’m replacing the spark plugs, should I also replace the ignition coils?

A: It is highly recommended to replace the ignition coils (coil packs) at the same time as the spark plugs, especially if your Focus has high mileage (over 80,000 miles). Coils degrade over time and frequently replacing both components ensures that your entire ignition system is fresh, preventing future misfires and maximizing the lifespan of your new spark plugs.

Q: Are coil/plug kits as reliable as buying parts separately?

A: Many modern coil/plug kits, such as the ECCPP and TAUTOY options reviewed here, meet high standards and are manufactured to match or exceed OE performance. They provide excellent cost-saving compared to purchasing high-end brand name coils and plugs individually, making them a very reliable choice for standard maintenance.
