N54 BOV Line Upgrade For BMW 1M, 135i, 335i, E89 Z4, E60 535i

HIGHLIGHTS • Allows for 1/4" Vacuum Line from MAP to BOV • 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.   IN THE BOX • ARM BOV Line Adapter • Mounting Screws • 1/4" Vacuum Line • 90 Degree Fittings • OEM Manifold Cap    FITMENT GUIDE Make Chassis Model Engine BMW E82 1 M Coupe N54 3.0L BMW E82 135i N54 3.0L BMW E88 135i N54 3.0L BMW E89 Z4 N54 3.0L BMW E90 335i N54 3.0L BMW E90 335xi N54 3.0L BMW E92 335i N54 3.0L BMW E92 335is N54 3.0L BMW E92 335xi N54 3.0L BMW E93 335i N54 3.0L BMW E93 335is N54 3.0L BMW E60 535i N54 3.0L
