Product Details

Upgrade your Mini Turbo Models, including Cooper S and JCW, with the ALTA BOV Spring Upgrade. This replacement spring offers a cost-effective, high-performance solution for your stock Blow Off Valve (BOV). By holding more boost between shifts, it significantly reduces turbo lag, enhancing overall performance. The carefully designed stiffer spring ensures normal BOV operation while maintaining increased pressure in the boost tubes, preventing power gaps.

Benefits:

Reduces turbo lag between shifts, boosting overall performance
Designed with a custom-made heat-treated 17-7 Stainless Steel Spring
Rated for over 7,000,000 cycles for long-lasting durability
Holds and vents up to 40psi efficiently
