Swirl Flap Blanking Plates Aluminum for BMW M47 M57 Engines

This kit permanently seals compromised intake tracts to stop loose swirl flaps from damaging your engine. When these factory vanes shear off, they frequently tumble straight into the combustion chamber. Installing these aluminium blanks keeps both passages open at all times. You retain normal fuel consumption and power while eliminating dangerous debris ingestion. The reinforced end caps expand and contract alongside your original manifold. Thick Viton O-rings resist extreme heat and chemical exposure for years of reliable sealing.

Benefits & Tips

• Direct Compatibility: Select the precise 22mm or 33mm profile to mount cleanly onto any M47 or M57 inlet runner.
• Steady Airflow: Clearing out the moving vanes removes intake dead spots for smoother throttle response.
• Leak Prevention: Polish the mounting faces before installing the included fibreglass gaskets to guarantee a pressure-tight joint.
