SYKRSS Ignition Coil & Spark Plug Kit for Lexus & Toyota 3.0/3.3L V6 — 6 Coils & 6 Iridium Plugs, Restores Ignition Performance

If your Lexus ES, RX or Toyota Avalon, Camry, Highlander or Sienna with a 3.0L or 3.3L V6 is showing misfires, rough idle, reduced throttle response, or a check engine light, this SYKRSS kit provides a matched replacement set of UF267 ignition coils and 4504 iridium spark plugs to restore reliable ignition performance.

How does this kit improve engine starting and throttle response?

The kit replaces all six coil-on-plug units and six iridium spark plugs at once, restoring consistent spark energy across cylinders. Consistent high-voltage delivery reduces misfires and uneven combustion so the engine starts more quickly and reacts more predictably when you press the accelerator.

• Matched coil-and-plug set avoids uneven wear between cylinders
• Iridium tips provide focused, durable sparks for quicker ignition
• High-grade coil windings preserve voltage under load

Will these parts fit my Lexus or Toyota model?

This kit is a direct-fit replacement for many popular 3.0L and 3.3L V6 applications from Lexus and Toyota. Always verify engine displacement and model year before purchase to confirm compatibility with your vehicle.

• Fits Lexus ES300 (1999–2003), ES330 (2004–2006), RX300/330 (1999–2006) and RX400 (2006–2008)
• Compatible with Toyota Avalon, Camry, Highlander, Sienna and Solara model years listed for 3.0L and 3.3L V6
• Replaces common OEM references such as UF-267, C1175 and part numbers listed on the product page

What symptoms does replacing coils and plugs typically resolve?

Replacing degraded coils and spark plugs often addresses intermittent misfires, rough idling, poor fuel economy, and sluggish acceleration. While other factors can cause similar symptoms, fresh coils and iridium plugs are a common, cost-effective repair when ignition components are aging.

• Eliminates cylinder misfires and smoothing idle fluctuations
• Reduces hesitation and surging during acceleration
• Helps restore fuel economy lost to incomplete combustion

How durable are these replacement components under everyday driving?

SYKRSS coils use corrosion-resistant materials and tightly wound copper conductors while the plugs feature iridium electrodes and precision-machined shells for long service life. Each component is tested to meet or exceed OEM performance expectations, helping the ignition system remain stable across temperatures and moisture exposure.

• Coils built with moisture- and heat-resistant epoxy and quality steel cores
• Iridium spark plugs for long-lasting electrode life and stable gaps
• Each part quality-checked for consistent voltage output before shipping

Who is this for? This kit is intended for DIYers, independent shops, and fleet technicians working on late-1990s through mid-2000s Lexus and Toyota V6 vehicles who want a full, matched ignition refresh. If you’re experiencing common ignition symptoms or performing preventative maintenance on a V6 engine, installing a complete set of SYKRSS UF267 coils and 4504 iridium plugs provides an efficient, direct-fit upgrade that simplifies diagnostics and helps restore smooth engine operation.
