HAMP Synergy are aftermarket products designed by Honda and are a step up from the "Honda Original Parts" products. They are not meant to compete with racing products, however, these pieces are quality and are used by some of top Japanese race teams such as Spoon. The HAMP oil filter can be used on any Honda, but was specifically designed for use with the VTEC and iVTEC cars in mind. Features include a unique release valve that dynamically adjusts to the conditions within the filter to keep the oil flow and pressure constant. The HAMP oil filter will last longer and filter better than any of the oil filters currently on the market.
