Engine & Cooling BMW E46

Your BMW E46 engine, from stock to wildly modified, will gain performance from the installation of proven performance parts. Don't let a weak spark plug wire lose the voltage needed to accurately ignite the fire that makes the power pulse. A performance engine uses all the available power across the full power band and when we increase power, we increase heat. A high-end build using the best internal components will not be very effective when your water temperature rises above 210°. A big motor (heat creator) needs an improved cooling and monitoring system to give the driver the information he needs to successfully finish this race.
