Parts for your 2006 Honda Elysion-Ignition coils

2006 Honda Elysion Ignition Coils

Ignition coils are absolutely relevant to the 2006 Honda Elysion. Honda’s technical literature for the K24A 2.4-litre and J30A 3.0-litre V6 engines specifies a coil-on-plug (COP) system, with one coil per cylinder. This is backed by Honda service manuals and parts catalogues for the Elysion platform, as well as application data from major ignition suppliers used across Australia and New Zealand.

On the 2006 Elysion, the ignition coil’s job is to step up the battery’s 12 volts to the tens of thousands needed to jump the spark plug gap, lighting the air–fuel mix cleanly. With a COP layout, the coils sit directly on top of the spark plugs, improving spark accuracy and reducing losses from old-school leads. The K24A runs four coils, while the J30A V6 runs six.

Coils aren’t a scheduled service item, but they do wear. Heat, vibration and oil contamination in the plug wells can shorten their life. If the Elysion starts hesitating under load, idles roughly, or triggers the check engine light with codes like P0301–P0306 (cylinder misfires) or P0351–P0356 (coil circuit faults), it’s time to test. A quick swap test—moving a suspect coil to another cylinder and seeing if the misfire follows—often pinpoints the culprit.

Best practice during servicing is to replace spark plugs at the correct interval (often around 100,000 km for iridium) and inspect the coils at the same time. If there’s oil in the plug tubes, address the rocker cover/tube seals first—oil can damage new coils. When fitting, seat the coil boots cleanly, use a small dab of dielectric grease on the inside of the boot, and torque the hold-down bolts to spec (around 10 N·m, check the exact figure for the engine). Spark plugs should be torqued correctly too, typically near 18 N·m for NGK iridium on these Hondas.

Quality matters. OEM or reputable brands that meet Honda specs are the go-to. It’s fine to replace a single failed coil, though on higher-kilometre vehicles some owners opt to refresh the full set to minimise repeat visits. Keeping the intake tract sealed and the engine earths clean also helps coil reliability. With the right parts and a careful fit-up, the Elysion’s ignition stays crisp, efficient and drama-free.

• Watch for misfires under load and rough idle
• Inspect plug tubes for oil, fix leaks before coil replacement
• Use proper torque and quality parts for long-term reliability

How many ignition coils does a 2006 Honda Elysion have?

The 2.4-litre K24A version uses four ignition coils—one per cylinder. The 3.0-litre J30A V6 carries six coils. Because it’s a coil-on-plug design, each coil sits directly over its spark plug under the engine cover, making access straightforward for inspection and replacement.

What are common symptoms of a failing coil on a 2006 Elysion?

Typical tell-tales include a check engine light, a shaky idle, hesitation on hills, and higher fuel use. Scan tools often show P0301–P0306 misfire codes or P0351–P0356 coil circuit faults. If the engine smooths out when a suspected coil is swapped to a different cylinder and the fault code follows, that coil is likely the issue.

Should ignition coils be replaced as a full set?

They don’t have to be. It’s acceptable to replace only the failed unit, especially on lower-kilometre vehicles. That said, on high-mileage Elysions, many workshops recommend replacing all coils together to reduce the chance of another coming good shortly after. Always pair coil work with fresh, correctly gapped iridium plugs if they’re due.
