This BDFHYK UF417 ignition coil and SP1018 iridium spark plug set is designed for listed Acura RSX 2.0L L4 and Acura TSX 2.4L L4 applications. It is intended for ignition service when the original coils or spark plugs have been diagnosed as worn, weak, damaged, or related to misfire symptoms. Before ordering, confirm exact year, engine, UF417-style coil reference, SP1018 plug reference, connector shape, and 4-coil / 4-plug service quantity.
| Make | Model | Listed Years | Engine | Fitment Check |
|---|---|---|---|---|
| Acura | RSX | 2002-2006 | 2.0L L4 | Confirm UF417-style coil, SP1018 plug reference, connector, and ignition layout. |
| Acura | TSX | 2004-2008 | 2.4L L4 | Compare the removed coil, spark plug reference, and service information. |
Fitment note: Do not order by Acura model name alone. Year, engine, coil connector, OE reference, and spark plug specification must match.
Ignition coils and spark plugs may need inspection when the engine has rough idle, hard start, hesitation, misfire symptoms, poor acceleration, poor fuel economy, or a check engine light. These symptoms can also come from wiring, fuel delivery, intake leaks, sensor faults, or compression problems. For service planning, review Acura RSX TSX coil and plug service steps.
Install on a cool engine, inspect old plugs for fouling, check plug wells and connector locks, and follow Acura service information for torque and gap. If symptoms remain after installation, continue diagnosis by checking wiring, fuel pressure, injector operation, intake leaks, and compression. This BDFHYK set is an OE-style aftermarket replacement, not a factory-branded Acura part.
