Product Description
Want to enhance the sound of your Silber Turbo on your Harley-Davidson? Our Blow-Off Valve Kit is engineered to deliver that unmistakable “whoosh” every time you chop the throttle—turning heads while adding real performance benefits.
Beyond the sound, the blow-off valve helps prevent compressor surge and reduces engine run-on during wide-open throttle (WOT) runs by safely venting excess boost pressure. This not only improves reliability but also helps protect your turbo system under higher boost conditions.
Each kit includes a high-quality silicone charge tube, a 25mm blow-off valve, and all necessary hardware for a straightforward installation.
We strongly recommend this upgrade for setups running more than 7 PSI of boost. If you're looking to add both function and attitude to your turbo Harley, this kit delivers on both fronts—making sure everyone hears you coming.
