The 2021-2023 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 2021-2023 Toyota Supra and 2019-2023 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.
