SYKRSS Ignition Coil & Iridium Spark Plug Kit 6-Coil/6-Plug for Lexus & Toyota 3.0L/3.3L V6 — Direct-Fit OE-Style

SYKRSS Ignition Coil UF267 paired with 4504 iridium spark plugs is a complete 6-coil/6-plug replacement kit engineered to restore reliable ignition for compatible Lexus and Toyota 3.0L and 3.3L V6 engines.

If your Lexus ES300/ES330/RX300/RX330 or a Toyota Avalon, Camry, Highlander, Sienna with a 3.0L or 3.3L V6 is showing misfires, rough idle, hesitation, or reduced fuel economy, this matched set replaces worn ignition coils and spark plugs in one service. The kit contains six UF267 coils and six 4504 iridium-tip plugs designed as direct-fit OE-style replacements to simplify installation and return balanced high-voltage output across all cylinders. Components are manufactured with upgraded materials and inspected to meet or exceed OEM performance expectations.

How will replacing both coils and plugs improve driveability?

Replacing coils and spark plugs together restores synchronized ignition timing and consistent spark energy to every cylinder, which reduces misfires and smooths idle. That improved combustion leads to steadier throttle response and can recover lost fuel efficiency.

• Eliminates intermittent misfires by restoring stable high-voltage output.
• Reduces rough idling and engine stumble during acceleration.
• Helps return factory-like throttle response and smoother starts.
• Iridium plugs extend service life and sustain precise spark gaps.

Will these parts fit my Lexus or Toyota model?

This kit is made to directly replace factory coils and plugs on many late-1990s to mid-2000s Lexus and Toyota V6 models; verify your engine displacement before ordering. The set replaces common OEM references (UF-267, C1175 and multiple other part numbers) and is intended as a plug-and-play substitute for compatible vehicles.

• Fits Lexus: ES300 (1999–2003), ES330 (2004–2006), RX300 (1999–2003), RX330 (2004–2006), RX400 (2006–2008).
• Fits Toyota: Avalon (2000–2004), Camry (2002–2006), Highlander & Sienna (various 2001–2008 V6 applications).
• Confirm engine is 3.0L or 3.3L V6 before purchase.
• Listed OEM cross-reference numbers included for parts matching.

What are the construction and durability features of this kit?

SYKRSS coils are wound with high-grade copper and insulated with Japanese epoxy resin to resist moisture, oil, and heat. The 4504 spark plugs use iridium-tipped electrodes and precision-machined shells for consistent spark and long service life—helping the ignition system resist voltage leaks and premature wear.

• Coils: silicon-steel cores, imported copper windings, epoxy potting for environmental protection.
• Plugs: iridium electrode and isostatic ceramic insulator for stable spark delivery.
• Quality control: each coil and plug tested for stable voltage output before packing.
• Kit contents: six coils, six spark plugs, and one installation manual.

How easy is it to install this matched coil-and-plug kit?

The set is designed for direct fit with factory locations and electrical connectors, typically allowing installation in under an hour for someone with basic tools and mechanical familiarity. The included manual walks through torque specs and sequence tips to help ensure correct installation and avoid common mistakes.

• Direct-fit replacement — no modification required for compatible models.
• Ships with an installation manual and all six coil-to-plug components.
• Torque and gap guidance included to prevent over-tightening and misalignment.
• Professional installation recommended if you lack mechanical experience.

Who is this for: The SYKRSS UF267 + 4504 kit is for owners and technicians servicing Lexus ES and RX series or Toyota Avalon, Camry, Highlander, and Sienna V6 vehicles with 3.0L or 3.3L engines who need a full ignition refresh. Choose this kit if you want a matched set of coils and iridium plugs that replace worn ignition components, restore smoother running, and reduce the chance of future coil- or plug-related misfires. Always confirm vehicle fitment and engine size before ordering to ensure compatibility.
