In this review the reviewer looks at the 6PCS UF267 ignition coils paired with 6PCS AGSP33C iridium spark plugs, a replacement coil pack set intended for 3.0L and 3.3L Toyota engines. The bottom line: this kit is for owners who need a full ignition tune-up at a reasonable cost and want parts that match original connector size and thread dimensions. Installation is straightforward for a competent DIYer and the combined ignition coil and iridium plug package restores engine smoothness and starting reliability in compatible Camry, Avalon, Highlander and other listed models.

Key Features

• Complete kit: Includes six UF267 ignition coils and six AGSP33C iridium spark plugs so you replace all cylinders at once for balanced performance.
• OEM fit references: Lists OE numbers such as 9091902234 and 610-58572 to help confirm compatibility with many Toyota 3.0L and 3.3L engines.
• Durable construction: Designed with materials and technology aimed at long service life and reliable ignition under varied driving conditions.
• Plug dimensions: Spark plugs have M14 thread diameter and 19mm thread length for a correct mechanical fit where specified.
• Simple replacement: Coil connector and size match original equipment, allowing installation without special tools for most users.
• Value package: Buying a matched coil and iridium plug set reduces parts mismatch risk and can be more economical than separate purchases.

Who It's For

This package is best for Toyota owners with 3.0L or 3.3L engines who need a full ignition system refresh and prefer replacing all coils and plugs at once to restore engine smoothness. It suits DIY mechanics and independent shops that value parts with OE cross-references and matched fitment details.

It is not intended for vehicles outside the listed models or later-generation engines without verifying fitment; some customers have reported fit ambiguity when used in other makes or newer model years, so buyers with unusual or aftermarket cylinder heads should look elsewhere or confirm measurements first.
