LCWRGS Ignition Coils for Infiniti G35 FX35 M35 & Nissan 350Z — Set of 6, Direct-Fit UF401 Replacement, High-Energy Copper Winding

LCWRGS ignition coil pack set (6) is a direct-fit replacement for the 3.5L V6 engines in Infiniti G35, FX35, M35 and Nissan 350Z, designed to restore spark performance and engine smoothness.

If your vehicle shows misfire symptoms, rough idle, or a check-engine light tied to ignition faults, replacing the coils with OE-compatible units can resolve many driveability issues. These LCWRGS coils match or exceed original equipment specifications, using high-conductivity copper windings and high-dielectric epoxy to maintain stable spark delivery under load. Supplied as a complete set of six, they swap in easily where UF401 and related OEM numbers are specified.

How do these coils fit my Infiniti or Nissan?

The LCWRGS set is engineered as a direct OEM-style replacement for specific 3.5L V6 model years and bolts into the factory mounting points with the stock harness. Fitment covers Infiniti FX35 (2003–2007), G35 (2003–2007), M35 (2006–2008) and Nissan 350Z (2003–2006). Each coil aligns with the original electrical connectors and spark plug locations for a bolt-on installation.

• Replaces OEM numbers: UF401, IGC0007, 22448AL61C and equivalents
• Direct-fit design for 3.5L V6 engine bay layout
• Includes full set of six coils for complete cylinder coverage
• No additional adapters or mod required

What performance or reliability benefits should I expect?

These coils are built to offer improved energy transfer compared with aged or failing originals, helping to reduce misfires and hesitation under acceleration. LCWRGS states their coils provide about 15% more energy than worn OE units, which can help restore throttle response and smoother idling. Enhanced insulation and copper winding reduce electrical losses and heat-related degradation over time.

• Higher energy output for more consistent spark
• Durable epoxy potting for moisture and heat resistance
• Improved conductivity through quality copper windings
• May help reduce fuel-wasting misfires when installed

How straightforward is installation and what’s included?

Installation is typically simple for anyone comfortable with basic engine work: remove engine cover (if present), unplug the coil harnesses, unbolt old coils, and fit the new units. The replacement set comes as six coil packs so you can change all cylinders at once, which is recommended for balanced performance. LCWRGS also includes a 24-month warranty and customer support for fitment or product questions.

• Comes as a six-piece kit for all cylinders
• Standard connectors match OEM harnesses
• 24-month warranty and seller support included
• Installation typically uses basic hand tools

Who this set is for: Drivers and independent mechanics who own compatible Infiniti or Nissan 3.5L V6 vehicles and want an OE-style replacement to address ignition-related faults, restore driveability, or preempt coil failure. This kit suits owners replacing all coils at once for consistent performance, those troubleshooting misfires, and anyone seeking a reliable aftermarket alternative that follows original fit and function standards.
