Ignition Coil & Spark Plugs for Audi Q5 (2018-2020) 2.0L I4

High-Output Ignition Coil & Spark Plugs for 2018-2020 Audi Q5

Replaces aging factory ignition components to restore optimal combustion, eliminate boost-related misfires, and maintain consistent idle quality.

The Stock Audi Q5 EA888 Ignition Shortcomings

The factory ignition coils on the 2.0L EA888 engine are notoriously susceptible to premature degradation, especially when subjected to the extreme thermal cycling of a turbocharged engine bay. Over time, the internal epoxy potting breaks down, leading to voltage leaks, secondary circuit resistance, and eventual misfires under heavy load. Standard OEM spark plugs suffer from accelerated electrode wear, widening the plug gap and forcing the coils to work harder, compounding the ignition failure cycle. This results in rough idling, sluggish throttle response, and unburnt fuel triggering check engine lights.

The Engineering Solution

This kit resolves chronic ignition breakdown by pairing robust, high-voltage ignition coils with advanced high-performance Ruthenium spark plugs. The upgraded coils feature superior thermal-resistant housings and enhanced internal copper windings, maximizing spark energy output while resisting heat soak from the cylinder head. The included Ruthenium spark plugs utilize state-of-the-art electrode technology, offering unparalleled oxidation resistance and anti-peeling characteristics compared to traditional iridium or platinum plugs. This combination ensures a highly concentrated spark, promoting complete combustion of the air-fuel mixture, stabilizing idle, and ensuring reliable power delivery throughout the entire RPM range, even under high manifold pressure.
