Ignition Coil & Iridium Spark Plugs for Acura TLX (2015-2020) 2.4L

High-Output Ignition Coils & Iridium Spark Plugs for 2015-2020 Acura TLX (K24W7 / UB1)

Restoring spark energy and optimizing combustion: This direct-replacement ignition coil and iridium spark plug kit resolves misfires and erratic idling while maximizing burn efficiency for the 2.4L Earth Dreams powerplant.

The Stock K24W7 Ignition Degradation

Over thousands of thermal cycles, the factory ignition coils on the UB1 chassis are highly susceptible to internal coil winding breakdown and epoxy degradation. This prolonged heat soak leads to increased electrical resistance, voltage leaks, and weakened spark output. Simultaneously, OEM spark plug electrodes wear down, widening the spark gap and forcing the ignition coils to work harder to jump the gap. This cascading failure results in perceptible hesitation under load, poor fuel economy, increased emissions, and dreaded P0300-series misfire codes that compromise drivability and overall engine efficiency.

The Engineering Solution

This comprehensive ignition overhaul directly addresses factory voltage deficiencies by pairing high-tension ignition coils with laser-welded iridium spark plugs. The upgraded coils feature premium copper wire windings and high-dielectric epoxy resin, ensuring consistent thermal stability and a stronger, more concentrated spark output under extreme cylinder pressures. The included iridium spark plugs utilize an ultra-fine wire center electrode, which significantly reduces the voltage required to bridge the gap. This precisely controlled spark promotes a more complete, uniform fuel burn within the combustion chamber, resulting in restored horsepower, smoother idle characteristics, and optimal fuel atomization across the entire RPM band.
