The 1998 Honda Accord EX primarily used a 2.3-liter inline-4 engine, with an optional 3.0-liter V6 available on EX-V6 models. This answer reflects the typical US-market configurations for that year.
Engine options for the 1998 Accord EX
The Accord EX from this year offered two engine choices in the United States: a 2.3-liter four-cylinder and, on higher-end configurations, a 3.0-liter V6.
- 2.3-liter inline-4 engine (engine code F23A). This powerplant provided roughly 135–150 horsepower and about 150–160 lb-ft of torque.
- 3.0-liter V6 engine (engine code C30A). This more powerful option produced around 200 horsepower and about 200–210 lb-ft of torque.
In short, the EX could be equipped with either a 4-cylinder engine or the V6, depending on the option package and model configuration.
2.3-liter inline-4 details
The 2.3-liter inline-4 (F23A) was the standard powerplant for many 1998 Accord EX models. It offered a balance of efficiency and performance typical of mid- to late-1990s Japanese sedans, delivering gains in city driving and highway cruising while keeping fuel economy reasonable for its class.
3.0-liter V6 details
The 3.0-liter V6 (C30A) was the available V6 option on EX-V6 versions. It provided noticeably more acceleration and smoother power delivery, with a broader torque curve that helped with merging and passing, at the cost of higher fuel consumption compared to the four-cylinder model.
How to confirm which engine your specific car has
If you’re trying to verify the exact engine in your 1998 Accord EX, use these steps to confirm.
- Check the engine code stamped on the engine block or valve cover (look for F23A for the four-cylinder or C30A for the V6).
- Inspect the under-hood label or emission sticker, which often notes the engine size and code.
- Review your Vehicle Identification Number (VIN) and build sheet or original window sticker to identify the engine family.
- Consult the owner’s manual or contact a Honda dealership with your VIN for precise confirmation.
These checks will help you determine which engine is installed in your specific 1998 Accord EX.
