Ignition Coil & Spark Plugs for Acura ILX (2013-2015) 2.4L I4

OEM-Grade Ignition Coil & Spark Plugs Set for 2013-2015 Acura ILX

What it Does: This complete ignition coil and NGK platinum spark plug kit replaces degraded factory ignition components to restore proper spark delivery, resolve misfire codes, and ensure optimal combustion in the 2.4L K24Z7 powertrain.

The Stock ILX Ignition Degradation

Factory ignition coils on the K-series engines are subjected to extreme thermal cycling and under-hood heat soak over tens of thousands of miles. The internal epoxy resin securing the secondary windings degrades over time, increasing internal electrical resistance. This causes a weak primary spark, leading to inconsistent cylinder pressures, incomplete combustion events, and dreaded P0300 to P0304 misfire codes. Accompanying this, worn stock spark plugs suffer from increased gap erosion, demanding higher voltage from the already stressed coils, ultimately diminishing throttle response and fuel efficiency.

The Engineering Solution

This direct-replacement kit resolves weak spark issues by utilizing high-dielectric epoxy in the ignition coils to resist heat soak and prevent internal shorts. The robust silicone coil boots provide maximum insulation against high-voltage arcing while sealing moisture out of the spark plug tubes. Paired with NGK Platinum spark plugs, this kit ensures a highly concentrated, stable spark kernel. The platinum center electrode resists carbon fouling and electrical wear, maintaining a precise gap over the service life. This synergetic pairing optimizes the air-fuel burn rate, restoring factory engine output, smoothing out the idle, and eliminating acceleration hesitation.
