autoexact Ignition Coil & Iridium Spark Plug Kit Set of 6 for Toyota/Lexus 3.5L V6 — Direct Replacement, Pre-Gapped

Autoexact ignition coil pack and iridium spark plug kit is a complete, direct-replacement six-cylinder ignition set engineered to restore reliable spark delivery for select Toyota and Lexus 3.5L V6 engines.

This kit combines six matched ignition coils and six pre-gapped iridium spark plugs designed to replace worn ignition components on many Toyota and Lexus models from the mid‑2000s through the late 2010s. It’s intended as a one-stop tune-up to address ignition-related drivability issues by supplying properly matched parts in a single purchase. Before ordering, confirm your vehicle year, make, model, and engine to ensure compatibility with the listed applications.

How will this kit improve rough idle, misfire, or hesitation?

Replacing aging coils and plugs often returns consistent spark timing and combustion stability. When misfires, rough idle, or hesitation stem from degraded ignition parts, installing fresh coils and iridium plugs can reduce those symptoms and help clear related diagnostic trouble codes.

• Six coil packs matched to the V6 firing order for balanced spark delivery
• Fine-wire iridium plugs pre-gapped for efficient ignition and combustion
• Epoxy-sealed coils resist moisture and arcing that cause intermittent misfires
• Included parts address cylinders 1–6 in one service to prevent repeat visits

What features ensure durability and reliable operation?

The coils use full primary and secondary copper windings and OE-style ignition circuitry to provide consistent high-voltage output. Durable materials and manufacturing tests help the assembly stand up to heat, vibration, and moisture in under‑hood environments.

• Epoxy-potted internals to reduce internal arcing and moisture ingress
• Heat-resistant PBT housing for long-term thermal stability
• High-voltage test performed on each coil to confirm insulation strength
• Fine-wire iridium electrodes for longer service life versus standard plugs

Is installation DIY-friendly and what tools or specs do I need?

This kit is built for direct replacement using common hand tools. Coils arrive factory pre-lubricated with dielectric grease to ease installation; typical torque specs for the spark plugs are listed to ensure a proper seal and avoid damage.

• Designed for bolt-on replacement with basic hand tools
• Pre-gapped iridium plugs to save adjustment time during install
• Recommended plug torque: 18.44–22.13 ft·lb (25–30 N·m)
• Includes six coils and six plugs so all cylinders are serviced together

Which vehicles and part references does this kit support?

This set fits many Toyota and Lexus models equipped with the 3.5L V6 across specific model years; verify fitment against your vehicle before purchasing. It’s intended as a direct-replacement option compatible with common OE reference numbers so you can match it to existing parts or repair manuals.

• Fits select Toyota and Lexus 3.5L V6 models (see fitment list for exact years)
• Compatible with OE reference numbers such as UF487, 6619, LFR6AIX-11
• Common applications include Camry, Avalon, Highlander, RAV4, Sienna, RX350, ES350, RX450h, Venza
• Seller offers VIN/vehicle check support if you’re unsure about compatibility

Who is this for: This ignition kit is aimed at vehicle owners and DIY mechanics who want a complete, reliable replacement for worn coils and spark plugs on compatible Toyota and Lexus 3.5L V6 engines. It’s a practical option for those experiencing ignition-related drivability issues or for anyone performing scheduled tune-up maintenance who prefers to replace all six coils and plugs at once to minimize repeat labor and parts sourcing.
