Bosch 0 221 604 02R Ignition Coil

Bosch Performance Ignition Coil

Building on the proven success of the legendary P65T ignition coil, the new Bosch Performance Ignition Coil delivers even greater ignition performance with an impressive 75.8mJ of spark energy at 14V. While retaining the convenience of a direct-fit coil-on-plug design, this next-generation coil produces over 37,000 volts to provide a stronger, more consistent spark under the demanding conditions of today's high-performance engines.

Ignition coils operate in one of the harshest environments on any vehicle, enduring extreme engine bay temperatures, continuous thermal cycling and high internal voltages. As modern turbocharged and supercharged engines produce two, three or even four times their original factory power output, the demands placed on the ignition system increase dramatically. A powerful, stable spark becomes critical for reliable combustion, particularly under high boost, elevated cylinder pressures and when using colder spark plugs.

Designed by Bosch Performance, this ignition coil converts the vehicle's 14-volt electrical supply into more than 37kV of ignition voltage with exceptional efficiency, helping maintain spark stability at high RPM and under extreme load. The result is improved ignition performance, excellent reliability and the confidence to support demanding street, motorsport and racing applications.

Unlike remote ignition systems that require custom brackets and high-tension leads, the Bosch Performance Ignition Coil retains the simplicity and reliability of a coil-on-plug installation, making it an ideal upgrade for performance enthusiasts seeking increased ignition energy without compromising factory fitment.

Please Note: A compatible 3-pin electrical connector is available separately.
