Parts for your 2007 Nissan Maxima-Ignition coils

2007 Nissan Maxima ignition coils: what they do and when to replace them

Ignition coils are absolutely fitted to the 2007 Nissan Maxima (VQ35DE 3.5‑litre V6). The Nissan Factory/Service Manual for the 2007 Maxima (EC/Engine Control section) specifies a coil‑on‑plug ignition system, with one coil per cylinder. Nissan’s parts catalogue lists individual “Ignition Coil Assy” units for this model/year, and major ignition component catalogues from OEM suppliers also specify direct‑fit coil packs for the 2007 Maxima. So yes—ignition coils are relevant, present, and essential on this vehicle.

On this Maxima, each coil sits directly over a spark plug to transform the 12‑volt supply into the high voltage needed for a clean spark. Coil‑on‑plug design improves reliability, eliminates long high‑tension leads, and lets the engine computer precisely control dwell and spark timing for better economy and smoother running. Healthy coils help with easy starts, crisp throttle response, and consistent power across the rev range.

They’re not a scheduled “replace by X km” item, but age, heat and vibration eventually take a toll—especially on the rear bank near the firewall. Practical servicing on a 2007 Maxima usually ties coil checks to spark plug changes. When the plugs are due, inspect each coil and boot for cracking, carbon tracking or oil contamination, and replace any suspect units with quality OEM‑equivalent parts.

• Typical coil fault symptoms: rough idle, misfire under load, hard starting, reduced fuel economy, and an illuminated MIL with P030X codes.
• Front bank coils are straightforward under the bonnet, the rear bank generally requires removing the upper intake plenum—plan extra time and new gaskets.
• If multiple coils are aged and the vehicle has high kilometres, replacing the full set can save repeat labour, particularly when the plenum must come off.

When fitting coils, keep connectors clean and seated, and tighten mounting bolts to service‑manual torque. Pair new coils with the correct long‑life spark plugs at the factory gap to reduce coil stress. After repairs, clear fault codes and road‑test to confirm the misfire counter stays at zero. Using reputable coils and fresh boots helps the Maxima’s VQ35DE stay smooth and reliable for the long haul throughout Aussie and Kiwi driving conditions.

Popular questions

How many ignition coils does a 2007 Maxima have and where are they?
It has six coil‑on‑plug units—one per cylinder. Three are on the front bank (easy access), and three are on the rear bank near the firewall, typically requiring removal of the upper intake plenum to reach.

Do all coils need replacing at once?
Not always. It’s acceptable to replace only the failed coil. However, on higher‑kilometre cars—especially when accessing the rear bank—many owners choose to replace coils as a set to avoid repeat labour and intermittent misfires.

Can bad spark plugs damage ignition coils?
Yes. Worn or incorrect plugs increase coil workload and heat, which can accelerate coil failure. Sticking with the factory‑specified long‑life plugs and correct gap helps protect the coils and maintain strong, clean spark.
