APR Ignition Coil & Spark Plug Kit (2.0T/2.5T 9A2 Porsche 4-cylinder engines) - KT100037

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 10 is designed to support consistent performance in high-heat and high-load conditions.

Includes: 4 ignition coils (MS100252) + 4 iridium spark plugs (Z1004081).

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 17% 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.

COMPATIBILITY: Configured for the engine family listed above using spark plug heat range 9. Spark plug OEM cross-reference: 06K905601B/D/K/M, 06Q905601E/L. Ignition Coil direct replacement for OEM stock part numbers 06H905110G, 079905110L, 079905110N, 079905110P, and 079905110R. 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.

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.
