Parts for your 2013 Nissan Pathfinder-Spark plugs

2013 Nissan Pathfinder Spark Plugs

Yes, the 2013 Nissan Pathfinder uses spark plugs. The Australian- and NZ-market R52 Pathfinder runs a 3.5‑litre VQ35 petrol V6, which relies on six long‑life iridium spark plugs for ignition. This is confirmed by Nissan’s Owner’s Manual (maintenance schedule noting spark plug service), the Nissan Factory Service Manual (engine mechanical and maintenance sections), and major plug catalogues used locally for parts selection. A diesel wouldn’t use spark plugs, but this model is petrol-only for 2013, so they’re absolutely relevant.

What do they do? Each spark plug fires a precisely timed spark to ignite the air–fuel mix, keeping starts crisp, acceleration smooth, fuel economy tidy, and emissions in check. The factory iridium design is built to go the distance, but like any wear item, performance fades over time.

Service-wise, Nissan specifies long replacement intervals for the iridium plugs (around 160,000–170,000 km under normal conditions). In tougher use—short hops, dusty roads, frequent towing, or lots of idling—it’s smart to inspect earlier. Tell-tales that plugs are past their best include rough idle, sluggish take-off, a jump in fuel use, hard starting when cold, or a check engine light with misfire codes.

When replacing, stick with OEM-spec heat range and iridium/platinum type. The plug gap is typically set from the factory at about 1.1 mm—don’t lever on the precious-metal tip. Install on a cool engine, threads clean and dry. Nissan specifies not to use anti-seize on plated modern plugs, it alters torque and can lead to over-tightening. Torque to about 18 N·m (13 ft‑lb) into the alloy heads. While you’re there, inspect the coil boots for cracking and add a light smear of dielectric grease at the boot lip to help seal out moisture.

• Recommended interval: plan inspection by 120,000–140,000 km if vehicle sees hard use, otherwise replace around 160,000–170,000 km.
• Symptoms of worn plugs: misfires under load, rough idle, poor economy, sluggish response, hard starts.
• Good practice: use quality OEM-equivalent plugs, correct torque, no anti-seize, and avoid re-gapping iridium tips.

With fresh plugs, the VQ35 runs smoothly, pulls cleanly up hills, and uses less fuel—exactly what owners want under the bonnet in Aussie and Kiwi conditions.

Popular questions about 2013 Nissan Pathfinder spark plugs

How often should spark plugs be replaced on a 2013 Pathfinder?
For normal driving, the long-life iridium plugs are typically due around 160,000–170,000 km. If the vehicle tows, does lots of short trips, or lives in dusty areas, have them checked earlier and be prepared to replace closer to 120,000–140,000 km to keep performance sharp.

What type and gap should be used?
Use OEM-spec iridium (or equivalent premium) plugs in the correct heat range for the VQ35 engine. The gap is factory-set at about 1.1 mm, avoid bending the fine-wire tip. A gentle check is fine, but if it’s off, replace rather than forcing an adjustment.

What torque and should anti-seize be used?
Tighten to roughly 18 N·m on a cool engine. Modern plugs have plated threads, and Nissan advises a dry install—no anti-seize. Using anti-seize can change friction and lead to over-torque. If coils or boots look tired, replace them to prevent future misfires.
