Revitalize Your Toyota and Lexus 3.5L/4.0L V6 with Autoexact

Everyday driving deserves dependable performance. When ignition components wear, you may notice hesitation, reduced power, or shakiness at idle. The Autoexact Ignition Coil Pack and Iridium Spark Plugs Kit combines six OE-style ignition coils with six fine-wire iridium plugs to deliver more consistent ignition and smoother running, helping you reclaim lost drive quality without any guesswork.

What’s inside and how it helps

Designed for direct fit on a long list of Toyota and Lexus models, this kit minimizes installation complexity. Each iridium plug arrives pre-gapped for quick, precise seating, while epoxy-potted coils stand up to heat and engine vibration for lasting ignition performance. The factory pre-lubricated green dielectric grease promotes true plug-and-play installation, and you’ll find recommended torque guidance to help with a clean, confident fit.
