APR Ignition Coil with Spark Plug Kit Grey 2.5T EA855.2 5-Cyl Audi RS Q3 | RS3 | TT RS Quattro | Cupra Formentor 2017-2026

Refresh your ignition system in one shot with an APR Coils & Plugs Pack-matched high-output ignition coils and iridium spark plugs engineered to work together for a stronger, more consistent spark. Each kit is a direct-fit upgrade designed to support smoother idle, sharper throttle response, and reliable performance under heat and load-whether you're stock or running higher boost and power upgrades.

ENGINEERED AS A SYSTEM: This package pairs APR high-output ignition coils with APR Iridium Pro spark plugs selected for your 5-cylinder application to deliver a stronger, more consistent spark and a complete ignition refresh in one box.

ENERGY OUTPUTS: APR ignition coils increase energy output by up to 14% over stock to help provide a stronger and more consistent spark. Iridium electrodes require less voltage to fire and support stable combustion as cylinder pressures increase.

A DIRECT-FIT UPGRADE: Direct plug-and-play coil replacement plus direct-fit iridium spark plugs-no wiring, coding, or tuning changes required. Always verify spark plug size, reach, gap, and heat range before installation.

HIGH-TEMP DURABILITY: Coils are engineered with upgraded internal components and batch-tested for reliability. Spark plugs feature an iridium electrode and copper core construction for efficient heat dissipation; heat range 9 is designed to support consistent performance in high-heat and high-load conditions.

COMPATIBILITY: Configured for the engine family listed above using spark plug heat range 9.
