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.

COMPATIBILITY: Configured for the engine family listed above using spark plug heat range 9. Spark plug OEM cross-reference: 06H905601A, 06Q905601E, 101905631G. Ignition Coil Direct replacement for OEM stock part numbers 06H905110G, 06H905110L, 06H905110P, 06K905601B, 06K905601L, 06K905601M, 06K905611C, 06M905606F, 06Q905601, 06Q905601E, 079905110R, 0P2905601, 0P2905601A, 9A790560100, 9A790560101. Always confirm fitment by application guide and visually confirm connector/boot style before installation.

ENGINEERED AS A SYSTEM: This package pairs APR high-output ignition coils with APR Iridium Pro spark plugs selected for your 4-cylinder application to deliver a stronger, more consistent spark and a complete ignition refresh in one box.

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.

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.

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.
