The IS Series intake system is a traditional, under hood intake system. By reducing turbulence in the pipe and providing a less restrictive flow through the high performance filter, each short ram intake system is engineered to provide improved horsepower and torque gains over the stock setup. Each system is built from 6061, T-6 aluminum alloy to ensure the lightest design possible. Most IS system is certified or pending by the California Air Resource Board and backed by Injen Technology’s limited lifetime warranty.
