Best Spark Plugs For 2017 Honda Civic: Comprehensive FAQ

Q1: Does the 2017 Honda Civic 1.5L Turbo use the same spark plugs as the 2.0L engine?

No, generally they do not. The 1.5L turbocharged engine operates at higher cylinder pressures and temperatures, requiring a specific spark plug heat range and material (often iridium or platinum) designed to dissipate heat more quickly. While some aftermarket plugs like the A-Premium offer cross-compatibility, it’s always best to use plugs explicitly rated for the turbo (1.5L) or non-turbo (2.0L) engine to ensure optimal performance and prevent potential engine damage.

Q2: How often should I replace the spark plugs in my 2017 Civic?

The service interval for modern iridium or platinum spark plugs in the 2017 Honda Civic is usually between 80,000 to 100,000 miles. However, if you have a modified 1.5L turbo or drive aggressively, it’s wise to inspect them and potentially replace them sooner, perhaps every 50,000 to 60,000 miles, to ensure peak engine efficiency and horsepower.

Q3: What happens if I use the wrong spark plug gap?

Using the incorrect spark plug gap can lead to several problems. If the gap is too small, the spark may be weak, causing misfires and incomplete combustion, which lowers fuel economy. If the gap is too wide, the ignition coil may struggle to bridge the distance, especially under heavy load (like in the 1.5T), potentially causing misfires, hesitation, or even premature coil failure. Always confirm the required gap size (often around 0.032 inches for the 1.5L turbo) and check it before installation.

Q4: Are NGK Laser Iridium plugs worth the extra cost over Iridium IX for my 2017 Civic?

NGK Laser Iridium plugs are considered the longest-lasting option, engineered for OEM longevity (100,000+ miles) thanks to the platinum pad on the ground electrode. The Iridium IX plugs are optimized slightly more for performance and throttle response, offering excellent spark but with a typically shorter lifespan than the Laser series. If your main priority is maintenance simplicity and maximizing mileage between changes, the Laser Iridium is worth the investment.

Q5: Can a faulty spark plug cause poor fuel economy in my car?

Yes. Worn-out or fouled spark plugs lead to inefficient combustion. When the spark is weak or mistimed, not all the fuel in the cylinder is burned, which wastes gas and lowers your mileage significantly. Replacing old 2017 Honda Civic spark plugs is one of the quickest ways to restore lost fuel efficiency.

Q6: Should I replace my ignition coils along with my spark plugs?

While not always necessary, it is highly recommended, especially if your Civic has over 100,000 miles or if you are already experiencing misfires. Old spark plugs demand higher voltage from the coils, stressing them out. If you are changing the plugs because of ignition issues, replacing the coils at the same time (as offered by the JDMON or UF781 combo kits) guarantees the entire ignition system is working harmoniously, reducing the risk of future engine misfires.
