UF333 Ignition Coil Packs & 7092 Double Iridium Spark Plug Compatible

In this review the UF333 ignition coil packs paired with 7092 double iridium spark plugs are assessed for Toyota and select Lexus and Scion models. The bottom line: this kit is for owners who need a direct-fit, long-life replacement to restore smooth idle and reduce misfires. The reviewer found the components match OE fit and wiring, the iridium plugs promise extended life, and the coils solve common ignition faults-making this a practical, cost-conscious choice for vehicles listed in the compatibility notes.

Key Features

• OEM Compatibility: Designed to replace OE numbers UF333 and 7092 so installation is straightforward and wiring aligns with factory connectors.
• Double Iridium Spark Plug: The iridium construction yields a consistent, stable spark and is rated for a long service life for fewer replacements.
• Improved Start and Idle: The coil and plug pairing helps provide better cold-start performance and smoother idle by reducing misfires.
• Durable Coil Construction: The coils use advanced thermoplastic connectors and stainless-steel springs to resist heat cycling and avoid connector fractures.
• Noise Suppression: Internal ferrite suppressor reduces radiofrequency interference for reliable engine electronics behavior.
• Complete Replacement Kit: Package includes four ignition coil packs and four double iridium spark plugs for a full bank service.

Who It's For

This kit is aimed at owners of compatible Toyota, Lexus HS250h, Scion, and Pontiac Vibe models who want an OEM-style replacement without dealer pricing; it is especially useful for those experiencing misfires, rough idle, or reduced fuel economy. Mechanics and DIYers who prefer direct-fit parts that match factory connectors will appreciate the straightforward swap and typical 20-25 minute per-bank installation time reported by users.

Those driving vehicles not listed in the compatibility notes or with unknown VIN-specific builds should check the second main picture and factory part numbers before buying. Drivers seeking the absolute top-tier racing coils or custom high-performance ignition systems should look elsewhere, since this kit targets reliable daily-driving replacement rather than performance tuning.
