Ignition Coil Pack UF486 with Iridium Spark Plugs SP433 - Fit

In this review the focus is on a combined ignition coil and spark plug kit intended for mid-2000s Ford-family V6 vehicles. The kit pairs an ignition coil labeled UF486 with iridium spark plugs SP433 and is aimed at owners of 2006-2009 Fusion, 2006 Lincoln Zephyr, 2006-2009 Mercury Milan, and 2006-2009 Mazda Tribute equipped with the 3.0L V6. The single biggest reason to consider this kit is replacement value: it bundles coil packs and iridium plugs with a 12 month warranty and lifetime after sales service, making it a practical repair option for those wanting a complete ignition refresh without sourcing parts separately.

Key Features

• Complete replacement set: Includes ignition coil UF486 and SP433 iridium spark plugs so customers can replace coils and plugs together for consistent ignition performance.
• Vehicle compatibility: Designed to fit specified 2006-2009 Fusion, Lincoln Zephyr, Mercury Milan, and Mazda Tribute 3.0L V6 models when OE numbers match, simplifying part selection.
• Durable coil construction: Coils use silicon steel, Japan-imported rubber, and varnished wire to improve longevity and resist heat degradation.
• Iridium spark technology: Iridium electrodes and engineered ceramic aim to deliver quicker starts and steadier acceleration compared with worn plugs.
• Warranty and support: A 12 month warranty plus lifetime after sales service gives added confidence for first-time installers and DIY mechanics.

Who It's For

This kit is best for owners of the listed 2006-2009 models who need a full ignition tune-up and prefer to replace coil packs and plugs at the same time. It also suits DIY mechanics and independent shops that appreciate a matched set and the convenience of a bundled warranty.

Drivers who are unsure about part numbers or who expect OE-level fitment without verification should check the OE references carefully before buying. Those with late-model engines, non-3.0L V6 variants, or who require dealer-origin parts may want to look elsewhere.

Pros & Cons

Pros

• Good value by bundling coils and iridium plugs for a single job.
• Durable coil materials aimed at longer service life than basic replacements.
• Iridium plugs promise improved starting and throttle response after installation.

Cons

• Fit and functionality reviews are mixed; some users report a misfire on one cylinder or plugs that fit loosely, so OE checking is essential before purchase.

Specifications

Our Verdict

This coil pack and iridium plug kit is a practical, cost-conscious choice for owners of the specified 3.0L V6 models who need a full ignition refresh. It offers durable coil construction and upgraded plugs at a sensible price, but buyers must verify OE numbers because some users report fit or performance variability. For those who check compatibility first, it represents good value compared with buying parts separately.
