MST Performance Cold Air Intake - Audi A4 1.4 TFSI (B9)
The MST Performance cold air intake replaces the factory airbox on the 1.4 TFSI in the Audi A4 (B9). It delivers cooler air to the turbocharger through a high-flow dry cone filter in a black heat shield with cover, for sharper throttle response and less turbo lag.
MST rates it at +7.5 hp at 5,300 rpm and +10 Nm at 2,600 rpm. MST recommends cleaning the dry filter every 20,000 km and replacing it at 60,000 km.
Note: Made for the B9 A4 with the 1.4 TFSI. A/C line routing varies on some cars, so the intake may need slight modification to fit. If you are unsure, send us a photo of your engine bay before ordering. Installation by a professional is recommended.
