A-Premium Ignition Coil and Iridium Spark Plug Kit, Set of 6 — Fits Toyota/Lexus 3.0L–3.3L, Bolt-On Coils

A-Premium’s kit combines six vehicle-specific ignition coils with six iridium spark plugs engineered to restore consistent combustion for compatible Toyota and Lexus V6 engines.

This complete replacement set is designed for 3.0L and 3.3L V6 engines used in a range of Toyota and Lexus models from the late 1990s through the 2000s. The package pairs bolt-on, blade-terminal ignition coils that mount on the valve cover with long-life iridium center-electrode spark plugs. Together they address common ignition-system wear points so owners can replace both coils and plugs at the same service interval for a cleaner install and predictable fitment.

Will this kit fit my Lexus ES or RX model?

The set lists direct fitment for Lexus ES300 and RX300 (1999–2003), ES330 and RX330 (2004–2006), and RX400h (2006–2008) equipped with V6 3.0L or 3.3L engines. Compatibility is based on OEM reference numbers and terminal/mount style matching the factory components.

How do the iridium spark plugs included benefit performance and maintenance?

Iridium is a refined alloy used for the spark plug’s central electrode that resists wear longer than standard materials. These plugs offer extended service intervals, a more stable idle under typical driving conditions, and consistent ignition characteristics throughout their life.

• Longevity: iridium electrode lasts significantly longer than conventional plugs
• Stable idle: tighter spark control helps maintain smoother engine idle
• Reliable starts: consistent spark reduces misfires during cold starts
• Maintenance: replacing coils and plugs together simplifies service

What are the ignition coil specifications and installation details?

The coils in this kit are 12V units with blade-style terminals and bolt-on mounting designed to sit on the valve cover like the original equipment. The set contains six coils to match six spark plugs, eliminating guesswork during a tune-up or repair.

• Coil terminal quantity: 4 per coil housing design compatibility
• Terminal type: blade-style electrical connection for factory harnesses
• Mount type: bolt-on for secure valve-cover attachment
• Voltage: standard 12V automotive ignition system

What warranty and part references come with the kit?

A-Premium backs the assembly with a one-year unlimited-mileage guarantee, allowing you to install with confidence while you evaluate performance. The product also lists several OEM cross-reference numbers so you can verify fitment against dealer parts diagrams.

• One-year unlimited-mileage warranty from A-Premium
