One of the most cost effective means of coaxing a significant degree more performance out of your Mercury, without spending a lot of money on complex modifications and high performance parts, is to add a good set of Mercury headers. A good set of Mercury headers can increase your horsepower and torque by up to twenty percent, as well as improve the efficiency with which your vehicle uses fuel. In addition, it can keep the running temperature of your vehicle lower, which is better for the health of your vehicle in general. The key to these improvements lies in the better airflow, both in and out. Removing exhaust takes power away from the engine, unless, like is done with a good set of Mercury headers, the engineering of the exhaust removal path eliminates sharp bends to the highest degree possible and seeks to keep the flow as freely moving as possible, avoiding complications such as turbulence or dead spots. Depending on your year and model of Mercury, as well as the degree of performance improvement you seek, you'll have a few types and styles of Mercury headers to choose from, with our well-organized online catalog making it easy to locate and compare the options.
