A-Premium Iridium Platinum Spark Plugs Pack of 4

A-Premium Iridium Platinum Spark Plugs (pack of 4) are high-durability fine-wire ignition plugs designed to replace factory units in many L4 Nissan and compatible vehicles, offering precise 0.044" gaps and long service intervals.

These spark plugs combine an iridium center tip with a platinum core to deliver consistent ignition performance, extended life, and resistance to wear. Engineered with a 12 mm thread diameter, 26.5 mm reach and a compact 51 mm insulator height, they match OEM dimensions for many 4-cylinder applications, including numerous Nissan Altima, Sentra, Versa, Rogue, Cube and other models. Each pack contains four plugs built to a 5000-ohm resistor specification to reduce radio interference while maintaining reliable spark delivery.

Which vehicles will these A-Premium spark plugs fit?

These plugs are specified for many Nissan 4-cylinder engines across model years and also fit a selection of other makes that share the same thread, reach and gap. Check the detailed fitment list and cross-reference part numbers before ordering to ensure compatibility with your engine code and body style.

• Common fits: Nissan Altima, Sentra, Versa, Rogue, Cube, Frontier, NV200, Micra
• Other compatible models: Chevrolet City Express, Suzuki Equator where applicable
• Factory gap set to 0.044 inch; thread diameter 12.00 mm and reach 26.50 mm

How do these spark plugs affect performance and longevity?

Iridium on the center tip and a platinum core reduce electrode erosion, which helps preserve spark quality over long mileage. That durability supports more consistent combustion, easier starts and steadier idle compared with older worn plugs.

• Designed for long service life — suggested replacement interval 80,000–100,000 miles
• Fine-wire center electrode improves ignition precision and fuel burn
• 5000-ohm resistor reduces electronic interference without sacrificing spark

What are the technical specifications I should confirm before buying?

Confirm thread size, reach, insulator height and gap to match your engine's OEM requirements. Mismatched dimensions can cause installation issues or engine running problems, so verify the numbers below against your vehicle's repair manual or existing plug.

• Center electrode: iridium; core material: platinum
• Gap: 0.044 in; thread diameter: 12.00 mm; reach: 26.50 mm
• Insulator height: 51.00 mm; hex size: 0.55 in; resistor: 5000 ohms

How should I install and maintain these spark plugs?

Install using the correct torque and anti-seize guidance for your vehicle; over-tightening or incorrect reach can damage the cylinder head. Replace all cylinders’ plugs at the same time and inspect ignition components for wear to maintain consistent performance.

• Use a torque wrench following manufacturer torque values for 12 mm plugs
• Hand-start threads to avoid cross-threading, then torque to spec
• Replace as a set every 80k–100k miles or sooner if misfiring occurs

Who is this for: A-Premium Iridium Platinum plugs are intended for DIYers, independent mechanics and fleet managers who need a cost-effective, long-life replacement for OEM spark plugs in many 4-cylinder Nissan engines and compatible vehicles. Choose these if you want OEM-style dimensions, a fine-wire iridium tip for improved ignition consistency, and a platinum core for extended service life. Always confirm fitment with your vehicle year, engine code and part cross-reference before purchase.
