Does this intake require a tune for my BMW Z4?

No, this Injen SP Short Ram Air Intake is designed to work with your factory ECU and maintain safe air-fuel ratios without requiring an additional tune. It's engineered to be a direct bolt-on upgrade.

What is the benefit of the polished aluminum tubing?

The polished 6061-T6 aluminum tubing is smooth on the inside, which helps air flow more freely into the engine compared to the restrictive factory intake. This improved airflow can lead to noticeable power gains and a more aggressive engine sound.

What is included with this Injen intake system?

The kit includes the polished aluminum intake tubing, a custom heat shield, the Injen SuperNano-Web dry air filter, and all necessary hardware for installation. The filter is serviceable and can be cleaned for reuse.

Product Details

Injen is known for making well-built intake systems that help engines breathe better. This SP Short Ram Air Intake is designed specifically for your 2019-2023 BMW Z4 with the 2.0L turbo engine, aiming to unlock more of that factory potential. The stock intake can be pretty restrictive, choking off airflow to your turbo and limiting power. This Injen system replaces that with a smooth, uninterrupted path for air, letting your engine and turbo perform closer to their best.

The heart of this intake is the large 3.25-inch diameter tube, made from 6061-T6 aluminum. This smooth, polished aluminum tubing helps air flow more freely, and Injen has carefully designed the system to maintain safe air-fuel ratios without needing a tune. You'll notice a more aggressive engine tone when you step on the gas, and Injen's dyno testing shows gains of up to 10 horsepower and 9 pound-feet of torque at the wheels. It also includes a serviceable SuperNano-Web dry air filter that offers increased surface area for better airflow and filtration.

This kit comes with a custom heat shield to help keep hot engine bay air away from the filter, and it's designed for a clean installation that looks great under the hood. If you're looking to add a bit more responsiveness and an exciting sound to your Z4's 2.0L turbo, this Injen intake is a solid option.
