Audi B8 A4/A5 2.0T | Pierburg Diverter Valve

When the 2.0T engine was introduced, the rubber diaphragm in the original diverter valve failed regularly, even at stock boost levels.

The improved Pierburg diverter valve has a piston valve design that eliminates the original, failure-prone rubber diaphragm.

This mechanical design is more durable and is an excellent upgrade for all stock or modified 2.0T FSI & TSI engines.

Spend more time driving, less time fixing!
