Ignition Coil & Iridium Spark Plugs for Volvo V60 (2015-2016) 3.0L I6

Direct-Fit Ignition Coil & Iridium Spark Plugs for 2015-2016 Volvo V60

Restores proper ignition timing and combustion efficiency for the 3.0L T6 powerplant by replacing failing coils and worn plugs.

The Stock V60 Ignition Shortcomings

The factory ignition coils on the Volvo B6304T4 3.0L turbocharged inline-six are subjected to severe thermal stress. Nestled deep within the cylinder head under the engine cover, the coils experience significant heat soak during sustained boost conditions. Over time, thermal cycling degrades the internal epoxy resin and copper windings. As insulation breaks down, internal micro-arcing occurs, leading to weak spark delivery. Furthermore, OEM spark plug electrodes wear down, increasing the spark gap. This widened gap demands higher voltage from a deteriorating coil, creating a failure loop that manifests as hesitation under load, dropping fuel economy, and P0300-series misfire codes.

The Engineering Solution

This replacement ignition kit is engineered to exceed OEM thermal threshold specifications. The upgraded coils feature high-grade dielectric epoxy injection that eliminates air pockets, preventing internal arcing and maximizing voltage transfer. High-purity copper windings ensure rapid charge times and consistent spark energy under high cylinder pressures. Paired with advanced iridium spark plugs, this kit provides a highly focused spark. The ultra-fine iridium center electrode lowers the voltage requirement to bridge the gap, relieving electrical strain on the coils. A high-alumina ceramic insulator resists fouling and withstands extreme combustion temperatures, ensuring restored throttle response and long-term reliability.
