The 2007 Honda Odyssey has six spark plugs in total. The vehicle’s 3.5-liter V6 uses coil-on-plug ignition, so each of the six cylinders has its own spark plug and ignition coil.
Engine and ignition layout
The 2007 Odyssey comes with a 3.5-liter V6 engine (commonly referred to as a J35A variant) with dual overhead cams and 24 valves. In this setup, each cylinder is equipped with a dedicated spark plug and a corresponding ignition coil, delivering reliable ignition across all six cylinders. Three spark plugs reside on each bank of the V, reflecting the engine’s symmetrical cylinder arrangement.
The following list highlights the core facts about the spark plug arrangement for this model:
- There are six spark plugs total in the 3.5L V6 engine — three on each bank of the engine.
- Each spark plug has its own ignition coil (coil-on-plug), meaning there are six ignition coils.
In practical terms, maintenance involving spark plugs for this vehicle involves replacing all six plugs and, typically, ensuring the corresponding six coils are in good condition as well.
Maintenance considerations
Plug type and replacement intervals
For the 2007 Odyssey, use OEM-equivalent long-life spark plugs (often platinum or iridium). Copper plugs are not generally recommended for long-life ignition systems. Always rely on the owner's manual or a Honda dealer for the exact replacement interval and torque specifications. Many owners follow a roughly 105,000-mile interval for long-life plugs, but driving conditions and plug type can affect this schedule.
Summary
In summary, the 2007 Honda Odyssey has six spark plugs—one per cylinder—paired with six ignition coils in a coil-on-plug system. When replacing them, plan for a six-plug, six-coil maintenance job and consult the owner's manual for the precise service interval and installation specifications.
