LCWRGS Ignition Coil and Spark Plug Kit for 3.5L V6 Nissan/Infiniti — Set of 6, Direct-Fit UF550 Replacement

LCWRGS complete 6-pack ignition coil and spark plug kit replaces UF550 and related OE parts to restore reliable ignition for 3.5L V6 Nissan and Infiniti engines.

This all-in-one set includes six ignition coil packs and six spark plugs engineered to meet or surpass original equipment specifications for many Nissan and Infiniti 3.5L V6 vehicles from model years roughly 2007–2019. Designed as direct-fit replacements, the components aim to simplify servicing by providing matched coils and plugs in one package. The kit targets common failure points—aged coils or fouled plugs—that can cause rough idle, misfires, and reduced fuel efficiency.

Which vehicles and engines will this set fit?

The LCWRGS kit is designed for a broad range of Nissan and Infiniti models equipped with the 3.5L V6 (and a few 2.5L V6 G25 listings) across late-2000s to late-2010s model years. It is built as a direct replacement for OEM part numbers like UF550 and related references, so fitment is straightforward on compatible engines.

• Nissan: Maxima, Altima, Murano, Pathfinder, 350Z, Quest (various 2007–2019 model years)
• Infiniti: EX35, FX35, G35, G25, JX35, M35 (2007–2013 ranges listed)
• Direct OE-style connectors, bolt locations, and spark plug reach for compatible engines

How do these coils and plugs improve everyday driving?

New ignition coils and fresh spark plugs restore consistent spark energy and combustion timing, which helps smooth engine operation and can reduce misfires and hesitation. While exact gains vary by vehicle condition, improved ignition reliability typically leads to steadier idle and better throttle response.

• Designed to deliver up to approximately 15% more energy than aged OE coils
• High-dielectric epoxy and conductive materials for stable signal transfer
• Matched coil-and-plug set reduces installation guesswork and ensures compatible performance

What are the technical and installation highlights I should know?

The kit follows OEM dimensions and electrical characteristics so installation follows factory procedures without modification. Each coil has factory-style connectors and mounting points, and the plugs come with proper reach and heat range intended for the applicable 3.5L engines.

• Replaces OE codes UF550, C1670, 22448JA10C and related numbers
• Six coils and six spark plugs included — sold as a complete engine set
• Plug gap set to manufacturer spec and coil boots designed for secure seating

How can I verify fitment before purchasing?

Confirm your vehicle’s engine code, model year, and OEM part number against the replacement list. If you still have the original coils or packaging, compare part numbers; otherwise, consult a parts diagram or your vehicle’s service manual for the ignition coil part reference.

• Check existing coil part numbers or dealer parts lookup for UF550 and aliases
• Match engine displacement (3.5L V6) and model year ranges listed in the product details
• Reach out to the seller with VIN and engine code for definitive confirmation

Who is this for: This LCWRGS set is aimed at DIY mechanics, independent repair shops, and owners of Nissan/Infiniti vehicles with 3.5L V6 engines who need a cost-effective, direct-fit replacement for worn coils and spark plugs. It’s suited for drivers experiencing misfires, rough idle, or decreased responsiveness who want a matched six-cylinder ignition refresh without sourcing parts separately.
