KacuYelin UF487/UF507 Ignition Coil Pack + Double Iridium Spark Plugs Set of 4 for Toyota 2.5L/2.7L L4

Upgrade your 2.5L/2.7L Toyota and Lexus engines with KacuYelin

Designed for select Toyota and Lexus models, the KacuYelin UF487 ignition coil pack combined with a set of four double iridium spark plugs delivers a thoughtful, performance-minded upgrade. This kit targets reliable ignition, smoother starts, and a steadier overall engine feel without promising guarantees, while staying true to the data provided by the manufacturer. Expect a more consistent electrical path and a robust spark across a wide operating range, which can contribute to more confident daily driving.

The coil pack and high-performance spark plugs are built to endure typical engine conditions. The coil pack features high-purity copper windings and a silicon steel core, paired with heat-resistant epoxy resin to resist oxidation and corrosion. The spark plugs employ 360° continuous laser welding and cold extrusion processes, with iridium content up to 90% and premium ceramic insulation designed for high-temperature environments. These design choices are aimed at delivering stable ignition and durable performance over time.

Fitment and real-world use

This kit is intended for a broad group of 2.5L and 2.7L engines, including 2010–2017 Camry 2.5L gas models, 2009–2019 Highlander 2.7L, 2009–2018 RAV4 2.5L gas models, and related models like Sienna and Venza. To ensure a correct match for your vehicle, enter your car information (Year, Brand, SubModel, Liter, Aspiration) into the fit confirmation section and review the OE references listed in the description.

In everyday driving, the kit is designed to support reliable spark delivery and consistent coil performance. While results vary by vehicle and driving conditions, users commonly notice a smoother idle, more confident starts, and potential improvements in fuel efficiency when paired with proper maintenance and driving habits.
