The 2021-2024 Toyota Supra and the 2019-2023 BMW Z4 both equipped with the L4-2.0L turbo engine are mini-powerhouses from the factory, so the engineers at Injen Technology needed to design an intake that packed a serious punch to help this little 2.0L Turbo engine keep up with this athletic and sophisticated performer. The R&D team took these all-new powerhouses deep into the lab to extract the hidden power lurking under the hood. From start to finish, each aspect of Injen Technology’s traditional aluminum Cold Air Intake for the 2021-2024 Toyota Supra and 2019-2024 BMW Z4 was a true labor of love. The Injen SP2301 cold air intake has the cleanest installation on the market that is also available in multiple finishes for that personized look.

The OE intake tract on the 2.0L Turbo engine is very restrictive from the factory and limiting power output by choking the turbo. Our new SP2301 short ram air intake opens up that intake tract with a large 3.250" aluminum intake tube that allows that turbo and engine to breathe deep and produce the power that you’ve been craving.

The SP series of cold air intakes is Injen’s flagship system in their lines of traditional aluminum cold air intake systems. It provides an intake growl that will surely excite your senses as you open up that turbo 2.0L and let that turbo spool. The soul of this intake is found within 6061-T6 aluminum air intake tube that provides a smooth uninterrupted path for highly efficient airflow. Our engineers have painstakingly designed the intake to provide the highest levels of safe power, along with clean aesthetics that will impress every time you open your hood. In addition to the impressive power increase, the Injen team has ensured that a safe Air fuel (A/F) ratio has been maintained throughout the power band.

Additionally, the SP2301 intake includes a fully serviceable Injen SuperNano-Web dry air filter, which provides increased filter surface area allowing for greater airflow and unbeatable filtration. If that's not enough, the Injen SP performance intake provides power you can hear and feel! On our dyno, the SP2301 put down an impressive 10 additional horsepower and 9 pound-feet of tire-scorching torque!

This intake provides an aggressive and throaty tone that is unmatched in the aftermarket and one that you’ll enjoy every time you smash the accelerator! Want to add that personalized touch to your intake? You’re in luck, as Injen also offers this intake system in amazing finishes, SP2301P (Polished), SP2301WB (Wrinkle Black), and finally SP2301WR (Wrinkle Red). To top it all off, this SP CAI kit includes the unbeatable Injen Technology limited Lifetime Warranty!
