UF487 Ignition Coil & 6619 Spark Plugs Set for Toyota 3.5L V6

In this review of the UF487 ignition coil and 6619 spark plugs set, the bottom line is simple: this combo is for owners of Toyota and Lexus 3.5L V6 models who need a direct-fit, value-minded replacement that restores reliable ignition performance. The reviewer found the set to be a straightforward swap for compatible Camry, Avalon, Highlander, RAV4, Sienna, Venza and select Lexus models, and highlights that the primary reason to buy is the combination of OE-equivalent fit and durable materials intended to reduce misfires and clear check engine lights.

Key Features

• Multivehicle compatibility: Covers many 3.5L V6 Toyota and Lexus applications so buyers can expect a direct-fit replacement for the listed model years.
• Durable coil construction: Coil packs use silicon steel, high-pressure rubber sleeves and imported epoxy to resist cracking and short circuits under normal use.
• High-grade winding: Germany-imported venameled wire inside the coils is intended to maintain stable high-voltage output across engine speeds.
• Iridium spark plugs: The 6619 plugs feature fine iridium electrodes and CNC-machined metal parts for consistent ignition and faster startup.
• OE-level fit and function: The set is made to meet or exceed original equipment form, fit and function for a plug-and-play swap.
• Complete kit: Includes six ignition coils, six spark plugs and a manual so a full-bank replacement is possible in one service session.

Who It's For

This kit is best for owners of 3.5L V6 Toyota or Lexus vehicles listed in the fitment information who are experiencing misfires, rough idle, poor fuel economy or a persistent check engine light related to ignition. It is also a sensible choice for DIY mechanics who prefer replacing the full set at once rather than mixing old and new parts.

It is not intended for engines outside the stated 3.5L V6 applications or for drivers who require OEM-branded parts for warranty reasons; verify year and engine code before purchase to ensure compatibility.

Pros & Cons

Pros

• Direct-fit compatibility across many Toyota and Lexus 3.5L V6 models makes installation straightforward.
