Blow Off Valve / Billet Atmospheric // SKU: 16-313

The factory plastic diverter valve is notoriously weak, often leaking under high boost and robbing your machine of power. Upgrade your charge system with the BMP Billet Aluminum Diverter Valve (Atmospheric). Machined from premium billet aluminum, this blow-off valve is engineered to hold massive boost pressure while venting directly to the atmosphere—giving you that signature, aggressive turbo "swoosh" sound every time you let off the throttle. Because of its critical role in maintaining boost under heavy loads, we proudly feature this exact valve as an upgrade option in our comprehensive Stage 2 Performance Kit!

Key Features:

• Premium Billet Construction: Eliminates the cheap factory plastic valve that is prone to cracking and leaking under heat.
• Aggressive Sound: Vents directly to the atmosphere for a loud, head-turning turbo blow-off sound.
• Holds More Boost: Designed with upgraded internals to snap shut and hold peak pressure efficiently, improving throttle response.
• Complete Installation Kit: Includes our CNC-machined billet intake plug, high-flow vent filter, and clamp to safely block off the factory recirculating tube and keep dirt out of your valve.
• Stage 2 Proven: Featured as a selectable performance upgrade in our complete Stage 2 Performance Kits.
