Looking for more CHHHHH in your XP Turbo? BMP has your quick fix! This kit easily allows you to convert your diverter valve to sound like a traditional atmospheric blow off valve. We do this safely by blocking the intake tube with a billet plug (not a cheap plastic one that can crack and cause leaks) and an air filter over the outlet of the diverter valve. This vents your diverter valve to atmosphere and while keeping dust and dirt out. We DO NOT recommend using this when riding in wet or muddy conditions. Unlike an actual atmospheric blow off valve, the BMP diverter to atmosphere kit allows you to quickly switch back to the factory diverter setup for extreme conditions. Works with the factory diverter valve or the BMP billet diverter valve.
