Turbosmart 15-19 Ferrari 488 3.9L V8 Twin Turbo Kompact Dual Port VR31 BOV

The Turbosmart Kompact Dual Port VR31 Blow-Off Valve is built with a billet aluminum body, offering a strong foundation for its precise operation. This valve is specifically designed for the 3.9L twin-turbo V8 found in the 2015-2019 Ferrari 488. Its dual-port design means it recirculates some of the vented air back into the intake system while releasing the rest to the atmosphere, helping to reduce turbo lag and protect your turbochargers from compressor surge.

Engineered for the demanding environment of a high-performance twin-turbo setup, this Kompact BOV features a unique spring bias system. This system allows it to hold boost pressure effectively, even under aggressive driving conditions, while still venting excess pressure quickly when you lift off the throttle. The billet aluminum construction ensures durability and resistance to heat and vibration, common issues in the engine bay of a vehicle like the 488. Installation is designed to be straightforward, replacing the factory unit with minimal modification.

This valve is a popular choice for 488 owners looking for improved throttle response and a more audible, yet refined, blow-off sound. It's a well-built component that contributes to the overall performance and longevity of your twin-turbo system. Please note that this part is not CARB approved and cannot be shipped to California.
