UF350 Ignition Coil & 4505 Double Iridium Spark Plug Kit for Nissan

In this review of the UF350 ignition coil and 4505 double iridium spark plug kit, the bottom line is simple: this is a practical, cost-conscious replacement for owners of Nissan 2.5L L4 models who want smoother idle and restored engine power. The kit is specifically compatible with many 2002-2006 Altima, 2002-2008 Sentra and 2002-2013 X-Trail 2.5L engines, and includes four ignition coil packs and four double iridium spark plugs for a full-bank service. It is aimed at DIY installers and independent shops that value parts matching OE fit and improved cold-start performance.

Key Features

• Compatibility: The kit fits a wide range of Nissan 2.5L L4 models, making it convenient for owners of Altima, Sentra and X-Trail vehicles to replace all four coils and plugs at once.
• Double iridium spark plugs: The plugs use double iridium for a longer working life and consistent, stable spark that helps preserve fuel economy and combustion efficiency.
• UF350 ignition coils: Coils are built with premium materials and an internal ferrite noise suppressor to reduce radio frequency interference and transfer high voltage reliably.
• OE-replacement fit: Each component either matches or improves on OE design, so installation is straightforward and fast for someone comfortable with basic engine work.
• Complete kit: Includes four ignition coil packs and four double iridium spark plugs so you can replace the full set without sourcing parts separately.
• After-sales support: The brand offers 24-hour customer service and a one-year product service policy for installation or quality issues.

Who It's For

This kit is best for Nissan owners with 2.5L L4 engines who want a full ignition service in one purchase: DIY mechanics who prefer a single kit to replace all four coils and plugs, and independent shops that do routine tune-ups on 2002-2013 Altima, Sentra and X-Trail models. The clear vehicle compatibility list reduces guesswork when ordering parts.

It is less appropriate for owners seeking OEM-branded components or those who need an exact factory part number from a dealer; also, if you require an included installation manual, note this kit does not include one and assumes basic installation knowledge or shop assistance.
