BMW M57TU & M47TU intake valve suppression kit - Pack 4 or 6 plugs 22 mm or 33 mm

Optimize the reliability of your BMW diesel engine equipped with M57TU or M47TU blocks by anticipating a recurring problem: clogged and broken intake swirl flaps. Over time, the original swirl flaps become loaded with scale, become heavy, loose or even detached. This can cause fragments to fall into the engine, leading to serious engine failure.

This Inlet valve suppression kit BMW M57TU/M47TU is designed to replace your shutters with CNC-machined, high-strength aluminum plugs and associated gaskets. You can choose between two diameters: 22 mm (models prior to ~2000-2004) and 33 mm (models 2005 and +). But beware: the factory doesn't always fit the «classic» size. It's essential to dismantle the manifold and measure to confirm.

The kit includes :

• 4 or 6 aluminum caps machined on digital machines in France.

• 4 or 6 intake gaskets (suitable) + 1 large O-ring for EGR / intake if you opt for the EGR valve removal.

• Simple installation: even an amateur with standard tools can do it.

• Materials compatible with engine oil and high/low temperatures.

Advantages of installing this kit now :

• Immediate engine protection: no risk of intake flap fragments falling into the cylinders.

• Optimal operation: no dead air in the manifold, better combustion.

• Less clogging: by eliminating defective shutters, you reduce deposits and scale.

• Low power consumption and long service life: reliability at its best.

• Easy installation, without major vehicle modifications.
