Ignition Coil Pack UF267 and Iridium Spark Plugs 4504 Set of 6

In this review the reviewer tests the SYKRSS set of 6 ignition coil packs UF267 combined with six iridium spark plugs 4504 on V6 Toyota and Lexus models to judge fit, reliability and value. The bottom line: this kit is for owners of compatible 3.0L and 3.3L V6 engines who want a complete, direct-replacement ignition refresh without dealer pricing. It stands out for meeting OE form and fit expectations, straightforward installation, and restoring proper ignition behavior that can eliminate misfires and check engine lights when used as a targeted repair.

Key Features

• Complete kit: Includes six ignition coils and six iridium spark plugs so you can replace the entire bank in one service, avoiding mismatched components.
• OE compatibility: Designed to meet or exceed original equipment specifications so each coil and plug should fit directly in place on listed Lexus and Toyota V6 engines.
• Heat resistant construction: Coils are made from materials intended to withstand high under-hood temperatures for longer durability under typical driving conditions.
• Performance restoration: The set is intended to resolve common ignition issues such as misfires, rough idling and check engine lights related to coil or plug failure.
• Clear replacement references: Packaging and literature include the OE numbers for both coils and plugs, helping confirm compatibility before installation.
• Support and warranty: The package ships with a manual and the seller offers a 24-month support window for peace of mind after purchase.

Who It's For

This kit is best for owners and mechanics working on Lexus ES300/ES330, RX300/RX330/RX400, Toyota Avalon, Camry, Highlander, Sienna and Solara with 3.0L or 3.3L V6 engines who need a full-bank ignition replacement. It is a practical choice when diagnosing consistent misfires, recurring check engine lights tied to coil or plug fault codes, or when performing preventative maintenance on older V6 engines.

Shoppers who should look elsewhere include vehicles outside the listed model years or engines, and buyers who require OEM-branded parts from a specific dealer for warranty reasons. Also, those who need single spare coils rather than a full six-pack might prefer a different purchase option.
