A-Premium Ignition Coil and Iridium Spark Plug Kit for Toyota/Lexus V6 — Set of 6, 12V Coils & Long-Life Iridium

A-Premium’s kit pairs six iridium spark plugs with matching ignition coils to restore consistent ignition for many Toyota and Lexus V6 engines from 1999–2008.

This matched set replaces worn coils and spark plugs with components engineered for long life and reliable starts. The ignition coils are designed for valve-cover mounting with blade-style terminals, while the iridium central electrodes extend service life and help maintain steady idle and smoother throttle response. Fitment covers a range of Toyota and Lexus V6 models — double-check compatibility against your vehicle year and engine size before ordering.

Which vehicles will this coil-and-plug kit fit?

The A-Premium set is intended for specific Toyota and Lexus V6 platforms from the early 2000s. It covers both 3.0L and 3.3L V6 variants across multiple model years, so it’s suitable for common Camry, Avalon, Highlander, Sienna, Solara, Lexus ES and RX applications listed below.

How do the iridium spark plugs and coils improve performance?

Iridium plugs use a refined alloy at the center electrode for improved durability and a finer electrode profile, producing a more consistent spark. When combined with matched ignition coils, the result is steadier idling and dependable starts without large upgrades or engine modifications.

• Iridium central electrode for extended service life and consistent sparking
• 12V coils with blade terminals designed for bolt-on valve-cover mounting
• Specifically matched parts reduce misfires and support smoother throttle response
