The air filter is one of the most important components in increasing the efficiency of an engine. The more air enters the combustion chamber the more power and torque will develop.
For this reason, replacing the air filter with a high-performance element is usually one of the first changes made to an original engine, notably improving functionality and also aesthetics.
From Wisconsin USA, S&S Cycle presents the new air filters for Harley-Davidson Stealth Approved for Europe. This new range of filters combines a high intake air intake flow and a "muscle car" aesthetic, all in compliance with European emission regulations.
