The
U.S. Patent Office specifically requested performance comparison tests between
the Halotm and two other patents, the Wang and Lara spark plug
designs. These tests revealed significant improvements in both horsepower and
torque to the satisfaction of patent examiners.
In
December of 1997, Halo performed comparative dynamometer testing at Kuntz and
Company of Arkadelphia, Arkansas on a 360 cubic-inch displacement Chevrolet
racing engine. Keep in mind that racing engines are typically optimized to
squeeze every available horsepower out prior to our installing the Halotm
plugs.
