Meet the latest addition to the CTS Turbo lineup – the Diverter Valve Spacer specially designed for BMW N55 turbocharged engines. Crafted in-house, this spacer is engineered to unleash the compressed air from your turbocharger into the atmosphere, delivering that satisfying blow-off valve (BOV) sound with every gear change and throttle closure.
 
Thanks to strategically designed vent slots, you can enjoy the enhanced sound without the hassle of triggering the Check Engine Light (CEL). Our engineering team meticulously tested this spacer on various N55 vehicles, ensuring a worry-free experience.
