TRUSTED IN THE US: Founded in 1997, APR is headquartered in Opelika, Alabama and has become a global leader in quality, reliable performance aftermarket products for Volkswagen, Audi, Porsche, and other vehicles.

Includes: 6 ignition coils (MS100208) + 6 iridium spark plugs (Z1003101).

ENGINEERED AS A SYSTEM: This package pairs APR high-output ignition coils with APR Iridium Pro spark plugs selected for your 6-cylinder application to deliver a stronger, more consistent spark and a complete ignition refresh in one box.

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.

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.

ENERGY OUTPUTS: APR ignition coils increase energy output by up to 10% 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.
