This gauge package is engineered to be the best. The kit completely replaces one of the three center vents (your choice) and sits at a usable height. The backlight, illuminated needle, and face graphics of the gauge match the factory instruments perfectly. The gauge reads from 0-30 psi of boost and 30-0 in/hg of vacuum.

When we took a look at installing a new boost gauge kit in the S4, we first turned to our best-selling a-pillar gauge kit. However, the addition of the a-pillar/side curtain airbag worried us. The last thing that you need in an accident is a gauge turning into a projectile. During mock-ups and trials, we landed upon the center vent location. After many hours spent in prototyping and product sourcing, we perfected our Center Vent Boost Gauge. The central location of this kit is not only attractive and cohesive to the interior, it is easier to read at speed.

This kit includes a complete center vent pod, anodized aluminum bracketry for the gauge, all electrical and tubing hookups, and detailed install sheet. Full functionality of the vent, except for left-right direction, is retained. Installation is easy and takes roughly 1 hour.
