Best Ignition Coil For Acura RSX FAQ

Q1: What are the main symptoms of a failing ignition coil in my Acura RSX?

The most common symptom is an engine misfire, often felt as a jerk or stutter during acceleration, especially under load. Other signs include a rough engine idle, a drop in fuel economy, and the illumination of the Check Engine Light (CEL), often displaying a code like P030X (where X is the cylinder number misfiring).

Q2: Should I replace all four ignition coils at once, even if only one is bad?

While you can technically replace only the failed coil, it is highly recommended to replace all four simultaneously. Coils generally wear out at similar rates due to heat and age. If one coil fails, the others are likely close behind. Replacing them as a set ensures uniform performance and prevents sequential misfires that could damage your catalytic converter.

Q3: How long do ignition coils typically last on an Acura RSX (K20 engine)?

The lifespan of an original equipment (OE) coil pack often ranges from 80,000 to 100,000 miles. High-quality aftermarket and performance coils, such as those from NGK, should meet or exceed that range. Budget aftermarket options may last slightly less, which is why brands like SYKRSS offer their specific longevity metrics (e.g., 60,000 km).

Q4: Are generic aftermarket coils truly a suitable replacement for the K20 engine?

Many generic aftermarket coils provide sufficient performance for daily driving and are a great value, especially the combo kits that include spark plugs. However, the K20 engine, especially the higher-revving Type-S variant, requires reliable, high-voltage output. When searching for the best ignition coil for acura rsx, if you frequently drive aggressively or race, OE manufacturers like NGK often provide superior stability under extreme heat and high RPM conditions.

Q5: Does the Acura RSX Type-S (K20Z1) require a different coil pack than the base RSX (K20A3)?

No, both the Type-S and the base model Acura RSX utilize the same coil pack part numbers (such as UF311 or UF583). The fitment and electrical requirements for the ignition coils are identical across the 2.0L K-series engines used in the 2002–2006 RSX model years.

Q6: If I replace my coils, do I need to worry about the spark plug gap?

Yes, absolutely. Even if you purchase a combo kit, you should always verify the spark plug gap before installation. The correct gap is crucial for reliable ignition and optimal performance on the K20 motor. Check your owner’s manual or use the recommended specifications (typically around 0.044 inches or 1.1 mm for the RSX).
