Ignition Coil Pack Set of 6 for 3.5L V6 (FX35/G35/M35/350Z)
This AA Ignition coil set is designed to replace multiple OE numbers, providing a straightforward install for 3.5L V6 engines in FX35, G35, M35, and 350Z models. The kit’s coils are engineered to maintain stable high-voltage output, supporting consistent spark across all cylinders and improved combustion. The included packs cover a range of replacements, simplifying vehicle maintenance when replacing multiple coils at once. The design prioritizes reliability and compatibility with common market variants of the VQ35DE family.
Key features include: compatibility with UF401 and related part numbers, robust housing for heat exposure in engine bays, and a focus on restoring drivability by eliminating misfires and CEL-triggering faults. For owners experiencing uneven idling, hesitation, or reduced fuel efficiency, this 6-pack offers a balanced approach to comprehensive ignition system refresh.
maXpeedingrods UF401 Coil Pack Set With Iridium Plugs
The maXpeedingrods UF401 set pairs ignition coils with compatible iridium spark plugs, presenting a combined upgrade for Infiniti FX35, G35, M35, and Nissan 350Z 3.5L V6 vehicles from 2003 to 2008. This kit aligns with OE numbers UF401, UF-401, and GN10246, among others, ensuring a direct replacement path for the ignition hardware. The product emphasizes high-temperature tolerance and stable high-voltage output to promote reliable ignition and smoother acceleration, particularly under load or hot-weather conditions. Installation is designed to be straightforward for typical curbside service or home garage projects.
Notable details include optimized copper wiring and enhanced insulation to resist voltage leakage, contributing to consistent spark delivery. Potential buyers should verify exact vehicle year and trim to confirm compatibility, as the VQ35DE platform spans several model lines with nuanced electrical needs.
BDFHYK UF349 Coil Pack Kit for 3.5L V6 and More
The BDFHYK UF349 kit extends compatibility beyond the FX/Nissan lineup by covering Altima, Maxima, Xterra, Pathfinder, Murano, and related models with 3.5L or similar V6 engines, including I35 QX4 combinations. This set provides replacement numbers UF349, UF349T, and C1406, offering a broad cross-reference for customers who own multiple vehicles in the family. The coils employ PBT and PPO materials to resist heat, wear, and corrosion while maintaining strong spark performance. Direct replacement ease is stressed, enabling users to swap out coils without special tools or modifications in most cases.
Engineers emphasize durability during high-load operation and boosting ignition efficiency. Prospective buyers should confirm the OE part numbers for their specific vehicle, as some VQ35DE variants and year ranges may require exact cross-refs to UF401 family components or the UF349 family to achieve optimal ignition stability.
LCWRGS UF341/UF401 Replacement Coil Pack Set
The LCWRGS coil packs focus on direct OEM design alignment for the FX35, G35, M35, and 350Z’s 3.5L V6 family, with replacements that cover UF401 and IGC0007 as well as 22448AL61C and related numbers. These coils are built to exceed OE specifications with copper conductors and high-dielectric epoxy to promote reliable spark delivery and longevity. The kit emphasizes straightforward fitment and broad vehicle compatibility, which helps simplify maintenance when multiple ignition coils need replacement across a model year range.
Users should verify the exact engine code and year to ensure the chosen cross-reference aligns with IGC0007 or 22448-AL61C style packs. The approach centers on enhancing ignition stability for sustained performance, reduced misfires, and smoother engine operation under varied driving conditions.
MAYASAF UF349 Replacement Coil Pack
The MAYASAF UF349 kit offers a one-pack option suitable for a range of 2002-2008 Nissan and Infiniti models with 3.5L V6, including Altima, 350Z, I35, and QX4 variants.

Buying Guide: Key Purchase Considerations For VQ35DE Coil Packs
When choosing ignition coil packs for a VQ35DE, consider the following factors to ensure optimal performance and reliability:
- Vehicle compatibility: Confirm the exact OE numbers your vehicle uses (UF401, UF349, IGC0007, 22448-AL61C, etc.) and the model year range. The VQ35DE family spans FX35, G35, M35, and 350Z with nuanced coil requirements.
- Quality and materials: Look for coils with heat-resistant housings, copper windings, and robust insulation to reduce misfires under hot engine conditions.
- OEM cross-reference: Choose products that clearly list cross-reference numbers to OE parts so you can verify fitment before purchase.
- Installation considerations: Some kits include plugs or require separate parts. Check whether the coils are a direct plug-and-play replacement and whether additional hardware is needed.
- Longevity and warranty: A longer warranty can indicate confidence in durability. Consider the climate and driving style when evaluating longevity expectations.
- Vehicle usage: For high-mileage vehicles or engines with intermittent misfires, a full coil-pack set can restore even performance across all cylinders more effectively than replacing single coils.
- Electrical system factors: If a current misfire is due to spark plug wear, ignition coil failure, or wiring issues, address root causes to maximize the impact of new coils.
Comparative considerations include cost per coil, installation simplicity, and whether a set or individual coils better match your maintenance plan. For fleet vehicles or multi-car households with VQ35DE-powered cars, selecting a proven, cross-referenced 6-pack or 8-pack often provides better value and maintenance consistency than buying singular units over time. Always verify vehicle year, engine code, and OE part numbers to avoid misfit coils and ensure optimal ignition performance.
