If you own a turbocharged vehicle, then chances are you have heard the term blow off valve. The job of your Geo Storm blow off valve is venting the built up boost when you let off the throttle, such as between shifts. On many factory setups the air is redirected into the exhaust system, however many aftermarket Geo Storm blow off valves vent directly to the atmosphere producing the distinctive hissing noise that we have come to associate with turbos. Here at Andy's Auto Sport we have a great selection of Geo Storm blow off valves from all of the leading brand names so no matter what your budget you can find the perfect blow off valve in our collection.

Blow off valves are an important component to keep your turbocharger functioning properly. Without a blow off valve in the system, the built up charge of compressed air would cause engine surging even when you lifted off of the throttle. This can be dangerous while on the road and can also damage the internal components of the turbocharger. In addition to their function, Geo Storm blow off valves also have a large cool factor. They look great under the hood, and with many valves offering tunable sound, you can customize the amount of noise they make when they vent to the atmosphere. Blow off valves are truly a must have item if you own a turbocharged vehicle.
