HIGHLIGHTS
• Prevents Surging and Over-Boosting
• Ensures Proper BOV Function
• Simple 30 Minute Installation
PROFILE
The ARM N54 BOV Line Upgrade will help your BOV open and close completely and quickly. The ARM N54 BOV Line Upgrade allows you to replace the standard 1/8" line with a 1/4" line, doubling the size to allow ample pressure. Upgrading the diameter of the vacuum line running to the BOV ensures proper BOV function. With a smaller 1/8" line you can experience surging or over-boosting if the BOV is not activating properly.CONSTRUCTION
The primary component of the ARM BOV Line Upgrade is the intake manifold adapter which is milled from one piece of aluminum to eliminate any source of leaks.
The 1/4" hose is made of high-temperature polyurethane to sufficiently withstand the heat generated by the engine. The 90 degree fittings come with Teflon tape pre-installed to ensure a tight, leak-free seal at all connections.

The ARM BOV Line Upgrade is the perfect solution for your N54's BOV to function properly.
