Professional Products® was founded in the late 1990s with a primary objective to provide quality high performance parts at better values than what originally existed in the marketplace. With the success of first polished small block Chevy intake manifolds, brand began expanding the range of products, always keeping in mind the end consumer's need for good parts at a good value. Although, one of te first products were Intake Manifolds, brand has expanded the range to include fuel systems, harmonic dampers and throttle bodies as well as various other accessories such as gaskets, water pumps, oil filters, gauges, coil covers, bolt kits and so on. Via brand's acquisition of "Retrotek Speed" Professional Products has also managed to expand into electronic fuel injection and ignition products as well.
