Injen Cold-Air Intake (CAI) 2007+ Scion tC P/N SP2114 The Injen RD and SP Series cold air intake systems are the perfect upgrade to your vehicle. After removing your factory airbox, the intake tube is directed directly behind the front bumper to acquire colder, direct air. Although most Injen intakes are a one piece design, several are a two piece design due to the mass air flow meters on some vehicles. You wont ever have a check engine light or have to trick or unplug a sensor with an Injen intake! Every RD system is certified or pending by the California Air Resource Board and is backed by Injen's lifetime warranty. Each Injen intake looks different in order to fit its intended application.

What Makes Injen Intakes better than their competition?Not only are all Injen Technology Intakes made in the USA, Injen cool air intake systems feature MR Technology, developed by Injen to maintain safe air/fuel ratio and highly efficient tuning. Injen also does extensive dyno tuning and r&d before releasing an intake, unlike many other companies who take an "if it fits, use it" attitude to aftermarket intakes.
