The SP Series was strictly built for the enthisiast craving top end power. Unlike the other Injen Series, the SP Series includes both intakes and some of the Super SES, Injen's new stainless steel exhaust line. Each SP Series is built from 6061, T-6 aluminum alloy to ensure the lightest design possible. Every SP Series is certified or pending by the California Air Resource Board and backed by Injen Technology's limited lifetime warranty.
