Whether you simply upgrade the software on your 2.0T or add a big-turbo kit, knowing your boost pressure at all times is vital. Fortunately, AWE's vent-mounted boost gauge for the B8 Audi A4 and A5 matches the OE interior lighting so its looks factory. What's more it reads up to 30psi of boost and 30-0in/hg of vacuum. The kit also allows airflow through the vent and comes with all necessary mounting hardware.
