The spark plug placement for a 2003 Toyota Echo follows a straight-line pattern along the engine's cylinder head. The vehicle is equipped with a 1.5L 4-cylinder engine, and the spark plugs are located in a row, with each plug corresponding to one of the four cylinders. The correct firing order is 1-3-4-2, with cylinder 1 being positioned at the front of the engine (near the timing belt). Ensure to refer to the vehicle’s service manual for specific torque specifications and installation procedures.
