Ignition Coil and Iridium Spark Plugs for Audi A5 (2015-2016) 1.8L

OEM-Grade Ignition Coil and Iridium Spark Plug Kit for 2015-2016 Audi A5

Direct Replacement Ignition Service Kit: Restores precise secondary ignition output and eliminates high-load misfires on the turbocharged 1.8L engine platform.

The Stock A5 Ignition Breakdown and Thermal Degradation

The turbocharged direct-injected 1.8L EA888 engine subjects coil-on-plug modules to intense cylinder head thermal cycling and dielectric breakdown. Over time, internal winding resistance increases and primary insulation deteriorates, resulting in weakened spark energy, voltage arc-over, rough idle, and unmetered misfires (DTC P0300–P0304) when under boost.

The Engineering Solution

This service kit provides high-output coil-on-plug assemblies engineered with dense-wound primary and secondary copper windings for reliable high-voltage induction. Paired with fine-wire iridium spark plugs, the assembly lowers the required ionization voltage and optimizes flame kernel propagation under combustion pressure. High-dielectric thermoplastic boots and direct-fit blade terminals withstand persistent engine bay heat soak while maintaining electrical integrity.
