This Power Wing kit is designed for the 1999-2001 Chrysler PT Cruiser. This kit features a simple, direct installation that is quickly adjustable to deliver between 25 and 50 horsepower. Like all NitrousWorks Power Wing kits, the kit for the PT Cruiser is a " wet" system that delivers metered amounts of fuel and nitrous oxide ahead of the mass air sensor. It installs easily in the air inlet with simple tools and provides a safe means to gain horsepower.
