N54 BOV Line upgrade

BMW N54 Blow-Off Valve Line Upgrade Kit

Unleash quicker boost response and rock-solid reliability.

Upgrade your BMW’s turbo system with our premium N54 Blow-Off Valve (BOV) Line Upgrade Kit, engineered for enthusiasts who demand performance, precision, and durability. The factory plastic lines and weak fittings are prone to leaks and slow response — our upgrade delivers the sharp, consistent boost control your twin-turbo N54 deserves.

Why Upgrade?
Your N54’s performance depends on airtight, responsive boost control. Stock plastic lines degrade over time, causing inconsistent venting and slower turbo response. Our upgraded kit ensures your BOV operates flawlessly under any driving condition — from daily commuting to full-throttle track runs.

Upgrade your vacuum line to your BOV with this adapter that allows you to tap right into your map sensor. Upgrading to this kit will help your BOV open and close quickly. This kit allows for 1/4 instead of the OEM 1/8 vaccuum line which will ensure you maintain proper BOV function. When you keep the smaller 1/8 vacuum line, it can cause over-boosting and surging.
