9029 Double Iridium Spark Plug for 2007-2019 Nissan Rogue

The X4XZ 9029 double iridium spark plug is a direct-fit replacement spark plug designed to restore reliable ignition, smoother idling, and improved throttle response for compatible Nissan and related models.

These 9029 double iridium spark plugs are built to match or exceed OE specifications for vehicles such as the Nissan Altima, Rogue, Sentra and several Infiniti models. With a durable iridium-tipped center electrode and precise construction, each plug aims to deliver consistent sparks, longer service life and easier installation. The set includes four plugs and X4XZ supports the product with one-year coverage and customer service if you need help.

How do these plugs affect starting and idle quality?

Iridium electrodes provide a smaller, more focused spark that helps ignite the air–fuel mixture more reliably. That improved ignitability typically produces quicker cold starts, steadier idling and fewer misfires compared with worn or lower-grade plugs.

• Double iridium center electrode for consistent sparks
• Designed to reduce miss and rough idle symptoms
• Improved cold-start responsiveness versus aged plugs

Will these replace the original 9029 plugs on my car?

Yes — the X4XZ 9029 is sized and specified to be a direct replacement for OE part number 9029 in the supported vehicle list. Always cross-check your vehicle year, engine size and the plug type shown in the second product image to confirm fit before purchase.

• Compatible with many Nissan models from 2007–2015 and select later years
• Also fits listed Infiniti and Chevrolet City Express applications
• Sold as a 4-pack to replace multiple cylinders at once

How long do these double iridium plugs last and what maintenance is needed?

Iridium electrodes are resistant to wear and can maintain good spark performance far longer than copper or nickel plugs. Expected service life varies by driving conditions, but these plugs are engineered for extended intervals — frequent inspection during regular tune-ups is still recommended.

• Durable iridium center for extended life (manufacturer life estimate provided)
• Inspect at routine service intervals for fouling or electrode wear
• Replace in sets to preserve ignition balance and performance

How easy is installation for a DIYer or technician?

The X4XZ 9029 plugs are manufactured to OE-style dimensions so they thread and seat like factory plugs. No instruction manual is included, but installation is straightforward for anyone familiar with basic engine maintenance; use proper torque and anti-seize practices where appropriate.

• Designed for direct-fit installation without modification
• Recommended to use a torque wrench and correct gap if required
• Professional installation available if you prefer not to DIY

Who is this for: The X4XZ 9029 double iridium 4-pack is aimed at vehicle owners and mechanics who need a long-lasting, OE-compatible replacement for worn or fouled plugs on supported Nissan, Infiniti and related models. It’s a good choice for owners seeking improved start-up behavior, steadier idle and a durable spark plug without changing ignition system components. If you’re unsure about fitment, confirm your engine size and compare with the compatibility list or contact X4XZ customer service for help.
