Improve spark performance on your 5-cyl or 6-cyl Volvo engine with our unique Ignite REV Coil Pack upgrade. Imported directly from our manufacturer in Japan, Ignite REV installs a power amplifier on your original coil pack to provide additional spark energy directly to the spark plug! The result is nearly doubling of ignition spark energy compared to the standard coils, burning the fuel within the cylinder more efficiently. This improvement in combustion efficiency reduces carbon monoxide and hydrocarbon emissions, while reducing fuel consumption and increase low- and mid-range torque. Note that the results are more pronounced on vehicles with turbo-charged engines.
