The firing order is 1-3-4-2-5-6. This sequence applies to the typical 1998 Civic engines found in US-market models, including the common D-series 1.6L engines and the sportier Si variant with a B16A2 VTEC engine.
In 1998, Civics were offered with several engine options. The majority used the 1.6-liter D-series family, while the performance-oriented Si model used a B-series 1.6-liter engine. Regardless of these variants, the standard firing order remains the same for the engines most owners encounter in this year. Always check your specific engine code in the service manual if you’re wiring spark plugs or diagnosing ignition issues.
Engine options in the 1998 Civic
Two primary engine families powered the 1998 Civic in many markets. The firing order tends to be the same across these common configurations.
- D-series 1.6L engines (e.g., D16Y7, D16Y8 and related codes): firing order 1-3-4-2-5-6.
- B-series 1.6L engine used in the Si (B16A2): firing order 1-3-4-2-5-6.
Note: Always refer to the exact engine code in your vehicle’s service manual, as there can be minor variances across production revisions or aftermarket components.
How to wire the ignition system safely
If you’re replacing spark plugs or wires, follow these steps to ensure you connect to the correct order and avoid misfires.
- Identify cylinder 1 position on your engine based on the front-facing orientation of the engine bay and the factory labeling in the service manual.
- Route or connect spark plug wires (or coil packs, if applicable) in the order 1-3-4-2-5-6 around the engine.
- Double-check each connection against the firing order diagram in your manual before starting the engine.
Properly wiring the ignition system according to the correct firing order reduces misfires, timing issues, and potential engine damage.
Summary
For a 1998 Honda Civic, the firing order is 1-3-4-2-5-6 across the common engine options. If you’re working on your vehicle, confirm the exact engine code in the service manual to be sure, especially if your car has aftermarket parts or an unusual trim level.
