K&N Engineering first offered cold air intake systems in 1987s. The original intakes were made of molded plastic intake tubes and a conical, cotton gauze air filter. In the late 1990s quite a few aftermarket manufacturers entered the market place such as Injen, AEM, Airaid, True Flow, AFE and Volant to name a few. In addition many manufacturers imported their designs from Japan and Korea lending to the popularity of the Japan domestic market (JDM) air intakes in sport compact markets. K&N and many of the other intake companies now offer metal tube design intake systems, allowing a greater degree of performance.
