1. MAYASAF UF349 [Pack of 1] Ignition Coil for Nissan Altima/350Z/Frontier/Maxima/Murano/Pathfinder/Quest/Xterra/Armada, Infiniti I35 QX4 UF349 C1406 5C1403

The MAYASAF UF349 is often the go-to budget replacement coil, especially when you only have one or two failing coils and want a quick fix without breaking the bank. These coils are built to meet or exceed OEM specifications, focusing on delivering reliable performance and resistance to the high heat cycles common in the tight VQ engine bay. Its wide compatibility range makes it a popular choice for various Nissan and Infiniti V6 models, including certain years of the 350Z (specifically 2004-2005 350Z fitments are noted).

Key features that stand out:
– Exact Fitment: Designed for direct, simple installation as a replacement unit.
– Premium Quality: Provides High Electrical Resistance and a strong spark even under demanding conditions.
– Reliable Performance: Resistant to Corrosion and Abrasion, ensuring a longer service life.

Pros:
– Very cost-effective budget option.
– Easy, direct installation.
– Backed by a 3-year quality service warranty.

Cons:
– While compatible with some 350Z models, it doesn’t cover all years (check specific fitment carefully).

Best for:
Budget-conscious owners needing to replace a single failing coil in earlier 350Z models.

Expert Opinion: For reliability on a budget, MAYASAF provides a solid performance foundation. However, when replacing coils in sets of six, many enthusiasts opt for UF401 variants, as the UF349 specification is generally tailored for slightly older or non-performance VQ setups.

2. Set of 6 Ignition Coil Pack Fits for 2003 2004 2005 2006 2007 2008 Nissan 350Z Infiniti FX35 G35 M35 V6 3.5 Coil Packs Replaces# UF401, 22448AL61C

This set provides six UF401-style coils, which are the standard required for the majority of the 350Z’s production run (2003–2008 V6 3.5L). This kit is specifically designed to eliminate common issues like misfires, hesitation, and poor fuel efficiency that arise from worn coil packs. LCWRGS claims these coils offer 15% more energy than standard OE coils, translating into a smoother idle and better throttle response.

Key features that stand out:
– Enhanced Ignition Coil: Claimed 15% more energy for improved performance.
– Direct OEM Replacement: Uses the UF401 standard, the correct coil pack for most 350Z V6 3.5L engines.

Practical Comparison and Buying Insights

Choosing the best ignition coil for nissan 350z depends entirely on your budget and goals. Here are a few key insights to guide your decision-making:

If budget is your primary concern and you only have one failing coil, both the MAYASAF and MAS single packs offer significant savings over dealer parts. Be aware, however, that the MAYASAF UF349 may not fit later 350Z models, whereas the MAS UF401 is a more universally correct replacement for the 2003–2008 3.5L V6 engine.

For those undertaking a major service, the UF401 Coil and Spark Plug Combo provides unparalleled value. If your car has over 70,000 miles and the plugs haven’t been replaced, this kit is highly recommended as the plugs are often the secondary cause of ignition breakdown.

When maximizing performance and demanding long-term reliability, nothing beats the Genuine NGK 6-piece set. While the cost is higher, the quality control is second to none, ensuring your Z runs smoothly under high load and for many years. Enthusiasts often prefer NGK to maintain original performance characteristics.

Remember to always confirm whether your specific Z model requires the UF349 or the UF401 standard—the UF401 is generally correct for the 3.5L V6 (VQ35DE), but checking cross-reference numbers is key.

Final Verdict on the Best Ignition Coil For Nissan 350Z

Making the right selection comes down to balancing cost, convenience, and performance expectations.

The Performance and Durability Pick: The 6 pc NGK Ignition Coils take the crown if reliability and OE quality are your main priorities. You pay a premium, but you get guaranteed performance.

The Best Value Comprehensive Solution: If you plan on a full tune-up, the UF401 Ignition Coil & Double Iridium Spark Plug 6PCS kit is the clear winner. You knock out two critical maintenance items with one affordable purchase, delivering a complete ignition refresh.

The Best Budget Replacement: For addressing an isolated misfire cheaply using the correct standard, the MAS 1Pc Ignition Coil Pack (UF401 replacement) is the most targeted and cost-effective solution.

Best Ignition Coil For Nissan 350Z FAQ

Q: How do I know if my Nissan 350Z coil packs are failing?

A: The most common symptoms of failing coil packs include engine misfire (often triggering the Check Engine Light/CEL), rough idling, poor acceleration and hesitation, and decreased fuel economy. If the misfire is constant, the ECU will usually show a specific code (P030X, where X is the cylinder number).

Q: Should I replace just the faulty coil or all six coils at once?

A: We strongly recommend replacing all six coils at once, especially if the car has high mileage (over 80,000 miles). Coil packs age similarly, and replacing just one often means another will fail shortly after, forcing you to repeat the installation process (which can be time-consuming on the VQ35DE engine). Replacing the set ensures consistent spark quality across all cylinders.

Q: What is the difference between the UF349 and UF401 coil pack specifications?

A: The UF401 is the standard coil type used in the 2003-2008 Nissan 350Z V6 3.5L engine, as well as many later Infiniti G35/FX35 models. The UF349 is typically found in some older VQ engines and early Nissan models. Always double-check your specific 350Z model year against the OE part number (like 22448-AL61C for UF401) before purchasing to ensure proper fitment.

Q: Is it necessary to replace the spark plugs when replacing the ignition coils?

A: While not strictly necessary if your spark plugs are new, it is highly recommended, especially if your plugs have more than 50,000 miles on them. A worn spark plug increases the strain on the ignition coil replacement, accelerating its failure. This is why combination kits often represent the best deal for a full ignition refresh.

Q: Are performance ignition coils worth the extra cost for a daily driven 350Z?

A: For a standard, daily driven 350Z, OE quality coils (like NGK) are more than sufficient. “Performance” coils generally offer a slightly higher voltage output, which is primarily beneficial for highly modified or forced-induction VQ engines that require a stronger spark to prevent blowout under high boost/compression.

Q: Can a novice DIY mechanic install these coil packs?

A: Yes, the coil pack replacement process on the VQ35DE is generally straightforward. The coils are plug-and-play and held in place by one or two bolts. The hardest part is often accessing the rear cylinders on the driver’s side due to limited space, but no specialized tools are required beyond basic metric wrenches and sockets.
