The 2013 Nissan Maxima has six spark plugs—one for each cylinder in its 3.5L V6 engine.
Engine configuration and spark plug layout
The 2013 Maxima uses a 3.5-liter V6 (Nissan’s VQ-series) with coil-on-plug ignition. Each of the six cylinders has its own spark plug and ignition coil, totaling six plugs. This arrangement is common for Nissan’s VQ engines and supports reliable ignition across all six cylinders.
Why six spark plugs?
Because the engine is a six-cylinder configuration, it requires a dedicated spark plug (and coil) for each cylinder to activate the air-fuel mixture in all chambers.
Key facts about the spark plug setup:
- Six spark plugs total—one for each cylinder on the 3.5L V6.
- Coil-on-plug ignition: each plug has its own ignition coil.
- Typical replacement interval is around 105,000 miles for iridium/platinum plugs, but always confirm with Nissan’s maintenance schedule for your vehicle’s VIN.
- Plug type can vary by market/trim; check the Owner’s Manual or dealer specification for the exact part number and gap.
- Accessing the plugs may require removing coil packs and, in some cases, other components to reach the cylinder heads.
Concluding: The Maxima’s six-cylinder V6 configuration inherently uses six spark plugs, with maintenance guided by the recommended plug type and interval for your specific vehicle.
Maintenance considerations
Before inspecting or replacing spark plugs, it helps to understand practical steps and what to expect during service.
- Verify the exact plug specification (type and gap) for your trim level and region.
- When replacing, disconnect the battery and relieve any fuel-pressure concerns if required, then remove the corresponding coil packs to access each plug.
- Use the correct torque specification when installing new plugs to avoid over-tightening or false seating.
- Consider inspecting or replacing ignition coils if misfires are observed or if coils show signs of wear during maintenance.
Concluding: Following the manufacturer’s guidance for plug type and replacement intervals helps maintain smooth operation, efficiency, and emissions performance for the 2013 Maxima’s V6 engine.
Summary
In summary, a 2013 Nissan Maxima has six spark plugs—one per cylinder in the 3.5L V6, with a coil-on-plug ignition system. Replacement intervals commonly run around 105,000 miles, though you should verify exact specifications and schedules in your owner’s manual or with a Nissan dealer for your vehicle’s VIN.

What kills spark plugs quickly?
Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail. In addition, if the cooling system isn't functioning correctly, it can cause the engine and spark plugs to overheat. This overheating can lead to the spark plug's electrode wearing out faster.
