A-Premium Set of 6 ignition coils paired with iridium spark plugs — a complete replacement kit engineered to restore V6 ignition performance for select Nissan, Infiniti and Suzuki models.

This kit bundles six direct-fit ignition coil packs with six high-grade iridium spark plugs to address misfires, rough idle, and diminished throttle response caused by worn ignition components. Each coil is manufactured to match OE dimensions and electrical characteristics, while the iridium center electrode resists wear longer than standard plugs. The set includes part cross-references and covers a broad range of 3.0L–4.0L V6 Nissan/Infiniti and compatible Suzuki applications, making it a convenient one-stop replacement for routine maintenance or troubleshooting ignition-related drivability issues.

Which vehicles will accept this A-Premium ignition coil and spark plug kit?

The kit is designed for many Nissan and Infiniti V6 models and some Suzuki applications. It lists precise model years and engine sizes so you can confirm fitment against your VIN or service manual.

  • Nissan: Altima 2002–2006 (3.5L), Frontier 2005–2019 (4.0L), Maxima 2001, 2002–2008 (3.0L/3.5L), Murano 2003–2008 (3.5L), NV series 2012–2019/2020 (4.0L), Pathfinder 2001–2012 (3.5L/4.0L), Quest 2004–2009 (3.5L), Xterra 2005–2015 (4.0L).
  • Infiniti: I35 2002–2004 (3.5L), QX4 2001–2003 (3.5L).
  • Suzuki: Equator 2009–2012 (4.0L).

How do iridium spark plugs improve performance and longevity?

Iridium spark plugs use a refined alloy on the center electrode that resists erosion far better than copper or platinum. That fine-tipped electrode stabilizes spark delivery, which supports consistent idle, reliable starts and improved combustion efficiency without needing frequent replacements.

  • Iridium center electrode for extended service life — approximately three times longer than conventional plugs.
  • Sustained, stable spark improves idle smoothness and throttle response.
  • Better combustion consistency can help fuel efficiency under normal driving conditions.
  • Cross-reference numbers included to verify correct plug selection.

What should I expect when installing these ignition coils and plugs?

Installation restores the ignition system to factory-style operation when the original coils or plugs have degraded. Replacing coils and spark plugs together is recommended to ensure matched wear and consistent firing across all cylinders; typical DIY users or professional technicians can perform the swap with common hand tools.

  • Direct-fit coils match OEM mounting points and electrical connectors for straightforward replacement.
  • Pre-gapped or specified gap iridium plugs reduce setup time—verify gap before install where applicable.
  • Replacing both components at once reduces the chance of repeat labor from failing mismatched parts.
  • Includes multiple reference numbers for cross-checking OEM equivalence.

What warranty and support does A-Premium provide?

A-Premium backs this ignition coil and spark plug set with a one-year unlimited-mileage guarantee, offering coverage for manufacturing defects. Customer support resources and clear part references help confirm fitment before purchase and simplify returns or warranty claims if needed.

  • One-year unlimited-mileage warranty for manufacturing defects.
  • Comprehensive part reference list included for compatibility verification.
  • Access to customer service for fitment or replacement inquiries.

Who is this for? Mechanics, DIY enthusiasts and vehicle owners who run Nissan/Infiniti V6 engines (and compatible Suzuki models) seeking a complete ignition refresh will benefit most from this kit. It’s suited for cars showing ignition-related symptoms, for scheduled maintenance, or when upgrading to longer-lasting iridium plugs to reduce service frequency. Verify vehicle fitment against the listed model years and reference numbers before ordering to ensure proper compatibility.

FAQ

Q: Does this kit fit my 2007 Nissan Altima 3.5L?

A: Yes — the set lists compatibility with Nissan Altima 2002–2006 3.5L and many 3.5L models; verify your VIN and engine code against fitment notes before buying.

Q: How long do the iridium spark plugs typically last?

A: Iridium plugs are rated to last significantly longer than standard plugs—often about three times the life—depending on driving conditions.
