DeutschTuing proudly offers Ignition Projects High Performance Coil Set for BMW B58. IP High Performance Ignition Coils are designed with our Patented Technology. IP Ignition Coils produce more spark energy than stock coils and also generate an ultra-fast, secondary spark discharge up to the highest RPM. The spark amperage is increased 100%, allowing the spark to reach many more molecules and therefore accelerate the ignition and combustion process. This is extremely important in forced induction applications but also improves the performance of normally aspirated engines.Engineered in Japan, Handmade in USA. Ignition Projects IP Coils are designed in Japan and handmade at our facility located in Santa Ana, California.
