Description
BMW Swirl Flap Delete & Intake Manifold Gasket Kit for M57N / M57N2 - 33mm
This kit kills two birds with one stone for those running the Australia Variant of the M57N2
You can delete the swirl flaps and replace all of the seals (including the steel sleeve bolt seals) that are not in our other swirl flap delete kit.
This kit removes the problematic swirl flaps that are known to degrade and eventually disintegrate. This then ends up being sucked into the engine, most of the time with dire consequences.
