2004 Honda Civic LX Engine: What’s Under the Hood
The 2004 Honda Civic LX (U.S./Canada models) is equipped with a 1.7-liter SOHC 16-valve inline-four engine, Honda engine code D17A1, a non-VTEC unit rated at about 115 horsepower and 110 lb-ft of torque. This trim uses a naturally aspirated, multi-point fuel-injected four-cylinder known for reliability and efficiency; VTEC was reserved for higher trims like the EX or specialized versions such as the HX.
Engine Overview
For the 2001–2005 “seventh-generation” Civic, Honda differentiated engines by trim. The LX sat between the base DX/VP and the sportier EX. In North America, the LX’s D17A1 engine prioritized everyday drivability, fuel economy, and low emissions rather than high-rev performance. While other regions had different trim names and engine mixes, the LX badge in the U.S. and Canada consistently denoted the non-VTEC 1.7-liter four-cylinder.

How It Differs From Other 2004 Civic Trims
Understanding nearby trims helps confirm you’re looking at the right engine for the LX, especially when shopping used or checking parts compatibility.
- EX: Uses the D17A2 with VTEC and higher output (about 127 hp)
- HX: Features a lean-burn VTEC-E variant (model-specific) aimed at maximizing fuel economy
- GX: Runs on compressed natural gas with a distinct engine setup
If a 2004 Civic is advertised with VTEC and labeled “LX,” double-check the VIN and engine tag; it may actually be an EX or have an engine swap.
Market Notes
Outside North America, engine offerings and trim names varied more widely (including 1.6-liter options and different VTEC configurations). The “LX” designation may not map one-to-one with U.S./Canada equivalents, so local documentation is the best guide for non-North American cars.
