The 2017 Infiniti QX60 uses a 3.5-liter V6 engine and has six spark plugs—one for every cylinder.
Engine and ignition configuration
The QX60's 3.5L V6 uses a coil‑on‑plug ignition system. Each of the six cylinders has its own spark plug and ignition coil, arranged with three cylinders on each bank in a classic V‑6 layout. This setup means a total of six spark plugs and six coil packs work together to ignite the air‑fuel mixture in every cylinder.
Maintenance considerations for spark plugs
Replacement intervals and plug type vary by trim and production specifics. Manufacturer guidelines for modern Infiniti/Nissan 3.5L V6 engines typically place spark plug replacement around 90,000 to 105,000 miles when using iridium or platinum plugs. Always consult the owner's manual or a dealer for the exact specification, torque values, and recommended replacement interval for your vehicle.
Summary
In short, the 2017 Infiniti QX60 has six spark plugs. Each cylinder is paired with its own plug, reflecting a six‑cylinder, coil‑on‑plug ignition design. For maintenance, follow the official guidance to ensure proper plug type and replacement timing.
