Crankcase Breather Adapter M57 M57N M57N2 M47 M47N
$42.00
Crankcase breather adapter, essential for every M57 / M47 above stage 2.
The standard crankcase breather cannot cope, and with high boost pressures, it allows large amounts of oil into the intake.
Outer tube diameter 25mm, inner 22mm
Made of solid 4mm stainless steel, professionally welded, with a perfectly flat surface that attaches to the cover.
Competitor adapters are made of 2-3mm sheet metal and warp during welding, meaning they don't seal properly when bolted on, which is why we created our improved version.
