Ignition Coil Pack UF351 and Iridium Spark Plugs 4505 Compatible

In this review of the UF351 ignition coil pack and 4505 iridium spark plugs set, the bottom line is simple: this kit is aimed at Nissan Sentra owners who need an affordable, factory-fit replacement to restore ignition performance. The reviewer found the set most valuable for cars with higher mileage showing symptoms like rough idle, slow acceleration, or increased fuel consumption, since the combination of silicon-steel coils and iridium electrodes promises longer life and quicker starting. This review focuses on fit, installation, and real-world tradeoffs based on product details and customer feedback.

Key Features

• Direct fit compatibility: Sold as a set specific to Nissan Sentra 2002-2006 1.8L L4, which simplifies parts selection for owners who match OE numbers.
• Durable coil construction: Coils use silicon steel, Japan-imported rubber, and varnished wire for improved long-term reliability compared with basic replacements.
• Iridium spark plugs: The 4505 plugs use an iridium electrode and high-grade ceramic to promote faster starts and more consistent combustion.
• OE cross-reference: The listing includes multiple OE numbers for both coils and plugs so buyers can verify fit against factory references before purchase.
• After-sales service: The manufacturer offers lifetime after-sales support, which can help if there are fitment or early-failure concerns.
• Value proposition: Sold as sets of four, the kit targets owners who prefer to replace all coils and plugs at once to avoid staggered failures and uneven performance.

Who It's For

This kit is best for Nissan Sentra drivers running a 1.8L L4 from model years 2002 through 2006 who want a full ignition refresh in one purchase. It suits DIY mechanics who can verify OE numbers and swap coils and spark plugs themselves, and for those seeking an economical path to restore starting and acceleration behavior.

Owners who need guaranteed OEM parts from a dealership or who have repeated early failures with aftermarket ignition parts may want to consider manufacturer-authorized replacements or higher-tier branded coils; some customer reports mention mixed durability results, so long-term reliability should be monitored.

Pros & Cons

Pros

• Good fit: many customers report the coils and plugs install easily and match factory dimensions.
