As one of the finest automobiles delivered from BMW, the E46 M3 has lived up to all its expectations as a true performance car. As enthusiasts try to squeeze any additional horsepower out of the inline 6 power plant, Agency Power has made that much easier with the release of their performance racing headers. The 321 stainless steel headers are a direct bolt on in replacement of your factory headers. The headers have thick flanges and amazing welds to insure longevity and strength compared to the competition. Each pair of headers includes the necessary sensor bungs. The headers fit on to the factory catpipes to increase air flow and improve mid to high range horsepower. In addition to improving upon horserpower, the headers will also help achieve some low end torque for the “off the line” power feeling.

Headers are sold as a complete set to fit the 01-05 BMW M3 E46 vehicle. Headers fit both the SMG and 6speed manual transmission cars. Professional installation is recommended. All Agency Power products come with a 90 Day limted warranty.
