Parts for your 2013 Nissan Pulsar-Spark plugs

2013 Nissan Pulsar spark plugs — what they do, when to replace, and how to keep them happy

Based on technical sources including the Nissan Electronic Service Manual (ESM) for B17/C12 Pulsar/Sylphy (2013), the Nissan Owner’s Manual and Maintenance Guide for AU/NZ, and NGK/DENSO application catalogues, the 2013 Nissan Pulsar runs petrol engines and therefore uses spark plugs. Both the 1.8-litre MR18DE and the 1.6-litre turbo MR16DDT (SSS) are spark-ignition engines with coil-on-plug ignition and iridium long-life plugs. So yes—spark plugs are absolutely relevant to any 2013 Nissan Pulsar spark-plugs servicing or replacement.

Spark plugs ignite the air–fuel mix, giving the Pulsar its smooth idle, crisp throttle response, and decent fuel economy. The fine-wire iridium design on these engines delivers a strong, reliable spark while resisting wear, which is why factory intervals are long and performance stays consistent across many kilometres.

For most Aussie and Kiwi 2013 Nissan Pulsar models with the 1.8 MR18DE, owners can expect a replacement interval around 100,000 km under normal conditions. The 1.6 MR16DDT turbo typically prefers shorter intervals—around 60,000 km—because boosted engines are tougher on plugs and benefit from the correct heat range and tighter gap. Always check the vehicle’s service booklet or ESM for the engine-specific interval and spec.

When it’s time, stick with OEM-spec iridium plugs (heat range and part number as per the engine). The gaps are factory set and generally shouldn’t be adjusted, especially on fine-wire iridium designs. A few pointers for the job: let the engine cool, blow out any debris from the plug tubes, and torque to spec (don’t overdo it). Modern plugs often have nickel-plated threads and typically don’t need anti-seize—follow the plug manufacturer’s note.

Common hints that the 2013 Nissan Pulsar spark-plugs are due include a lumpy idle, hesitation under load, slower starts on cold mornings, higher fuel use, and a flashing MIL with misfire codes (often P0300–P0304). While replacing plugs, it’s smart to inspect coil boots and look for oil in the plug wells (rocker cover gasket seepage), because those issues can mimic plug faults.

Done on time with the right parts, spark plug servicing keeps the Pulsar perky, efficient, and easy to live with under Aussie and Kiwi conditions.

Popular questions about 2013 Nissan Pulsar spark-plugs

What spark plug type does a 2013 Nissan Pulsar use?

The 2013 Pulsar uses long-life iridium spark plugs. The 1.8 MR18DE typically specifies an iridium plug with a 1.1 mm preset gap, while the 1.6 MR16DDT turbo uses an iridium plug of a colder heat range and a tighter factory gap. The exact part number can vary by engine and market, so it’s best to match by VIN or use a trusted application catalogue.

How often should spark plugs be replaced on a 2013 Pulsar?

As a guide for AU/NZ conditions: around 100,000 km for the 1.8 MR18DE and about 60,000 km for the 1.6 MR16DDT turbo. If the vehicle sees lots of short trips, dusty roads, or spirited driving, consider shorter intervals. Always confirm with the service schedule for the specific engine.

What are signs the Pulsar’s spark plugs need attention?

Rough idle, hesitation under load, sluggish acceleration, increased fuel use, hard starts, and a check engine light with misfire codes are the usual suspects. If those pop up, inspect plugs and coil boots, and check for oil in the plug tubes before it turns into a bigger headache.
