Pro-Filer Performance Products, Inc. got started in the engine building industry after realizing the need for a high quality, aerospace grade, cylinder head and intake manifold in the high performance aftermarket industry. We began in a niche “big motor” drag racing market since those were the engines we were involved with at the time. After seeing the improvements and horsepower gains over OEM parts of the same size, we saw the opportunity to expand the line to meet needs in various motor markets. Needless to say it has been an exciting 12 years.
