Autowxjq Iridium Spark Plug & Ignition Coil Set — 8‑Piece for Toyota/Lexus 4.6L‑5.7L, Pre‑Gapped Direct Replacement

If you're maintaining a Toyota Tundra, Sequoia, Land Cruiser or a Lexus V8 from the 2007–2022 model years, this Autowxjq kit gives you eight iridium-tipped spark plugs matched to ignition coil compatibility for a full-bank service. The plugs arrive pre-gapped to factory specifications, and the listing cross-references common OEM part numbers so you can confirm fitment before purchase. Backed by a 12-month warranty and customer support, the set is intended as a direct-replacement option for routine maintenance or mid-life ignition refresh.

Which vehicles and engines will these spark plugs fit?

This kit is engineered for V8 Toyota and Lexus models that use the listed plug types. It covers multiple years and engine displacements—primarily 4.6L and 5.7L V8s—used in Tundra, Sequoia, Land Cruiser and several Lexus platforms. Always verify with your vehicle’s service manual or the part-number cross-reference before installation.

• Toyota Tundra: 2007–2021 (4.6L and 5.7L V8 coverage varies by year)
• Toyota Sequoia: selected 2008–2022 4.6L/4.7L/5.7L model years
• Toyota Land Cruiser: compatible 2008–2021 5.7L V8 years
• Lexus GX460, LS460, LX570: compatible model-year ranges listed per engine size

How are these plugs prepared for installation?

The Autowxjq plugs come pre-gapped to the dimensions used in many OEM replacement scenarios, meaning you can install them without additional gap setting in most cases. They are iridium-tipped for a fine center electrode and designed for longevity in standard driving conditions.

• Pre-gapped to factory-like specifications for immediate installation
• Iridium center electrode for a thin, durable firing point
• Sold as a set of eight to service an entire V8 bank in one job
• Includes referenced OEM part numbers to confirm direct-replacement fit

What are the expected benefits of using iridium plugs with ignition coil replacements?

Using iridium plugs paired with healthy ignition coils typically supports consistent spark delivery, more reliable starts, and stable combustion characteristics across cylinders. Replacing coils and plugs together reduces mismatched wear and helps diagnose ignition issues more clearly when symptoms appear.

• Improved electrode durability compared with standard nickel plugs
• Consistent spark performance across all cylinders when coils are matched
• Reduced risk of misfires due to worn plug-to-coil interfaces
• Clearer troubleshooting if ignition-related symptoms persist after replacement

What installation tips and service suggestions should I follow?

Follow the vehicle manufacturer’s torque and installation procedures for spark plugs and ignition coils. It’s recommended to replace coils and plugs together when either shows signs of wear; this reduces future diagnostic uncertainty and helps ensure uniform firing characteristics.

• Use a torque wrench and the OEM torque specification for spark plugs
• Replace ignition coils and plugs at the same time when possible
• Check part-number cross-reference (e.g., 90919-02255 and others) for fit verification
• Inspect boots and wiring harnesses for signs of heat damage or corrosion

Who is this for: This Autowxjq ignition kit is aimed at owners and DIY mechanics of Toyota and Lexus V8 vehicles who need a full-bank spark plug solution that mirrors OEM specifications. It's useful for scheduled maintenance, ignition-system troubleshooting, or when replacing degraded coils and plugs together to restore consistent engine performance. If you’re uncertain about fitment, consult your vehicle’s service manual or a professional mechanic before purchase.
