A-Premium Ignition Coil & Iridium Spark Plug Kit — Set of 6, Direct-Fit for Toyota/Lexus V6

A-Premium’s set of six ignition coils with six iridium spark plugs is a direct-fit replacement kit for many Lexus and Toyota V6 models, designed to restore reliable ignition and long-lasting service life.

When an aging engine starts misfiring, stumbling at idle, or showing reduced responsiveness, the ignition coils and spark plugs are often the first components to check. This A-Premium kit bundles six bolt-on ignition coils (12V, blade terminals) with six iridium-tip spark plugs engineered to match factory fitment for a range of Lexus and Toyota V6 applications from 1999 to 2008. The components are supplied with cross-reference numbers commonly used in aftermarket and OEM listings, and the package includes a one-year unlimited-mileage guarantee for added confidence.

How does iridium in the spark plugs help performance?

Iridium is a hard, refined alloy used on the central electrode of these plugs; its durability and small electrode diameter improve spark consistency and longevity without claiming to cure specific engine faults.

• Smaller, durable electrode promotes a concentrated spark for consistent ignition events.
• Longer expected service life—typically longer than standard copper plugs.
• Stable idle characteristics and more reliable starts compared to worn plugs.
• Helps maintain combustion efficiency when paired with properly functioning coils.

Are these ignition coils an exact replacement and easy to install?

Yes — the coils are bolt-on style with blade terminals and mount on the valve cover, matching OEM mounting and electrical interface for the listed vehicles. Basic mechanical skills and common tools are usually sufficient for replacement.

• Coil terminal quantity: 4 connections per unit with blade-type terminals.
• Mounting type: bolt-on to valve cover for straightforward fitment.
• Voltage rating: 12V to match vehicle electrical systems.
• Install tip: inspect plug wells and harness clips, torque bolts to manufacturer specs.
