Audi B9 S4 Headlight Delete Kit

Direct cooler ambient air toward your Cold-Air Intake with our B9 S4 Headlight Delete Kit. 3D-printed in-house from ASA, it creates a dedicated airflow path from the headlight opening to the intake area, designed to support cooler intake air temperatures (IATs).

*ASA is specifically derived from ABS to better resist UV and will withstand those hot-V temps. It will never yellow, chalk, or become brittle outdoors. ABS degrades, fades, and snaps quickly under UV light

[Made to order. Estimated lead time: 1 week]

*Actual IAT changes depend on intake setup, operating conditions, and vehicle configuration*
