Injen 17-19 Audi A4 2.0T Polished Cold Air Intake

When you open the hood of your 2017-2021 Audi A4 Quattro, you'll see a polished aluminum intake tube from Injen. This SP series cold air intake is designed to let your engine breathe more freely, which can lead to improved performance. It includes the main intake tubing, a SuperNano-Web dry air filter, and all the necessary hardware for installation.

The intake tube is made from 6061-T6 aluminum and is mandrel-bent to create a smooth path for air. This design helps reduce restrictions compared to the stock intake. Injen claims this system can add up to 14 horsepower and 12 lb-ft of torque, while also maintaining a safe air-fuel ratio. The included SuperNano-Web dry filter doesn't require oil for maintenance, making it easier to clean and care for. You'll also notice a more aggressive engine tone when you accelerate.

This Injen cold air intake is made in Pomona, California, and comes with a limited lifetime warranty from Injen. It's designed as a direct fit, meaning no additional tuning is required for installation. Keep in mind that this intake is not CARB exempt and cannot be shipped to California or used on vehicles registered there.
