⚡ At a Glance
- • Sealing Performance: Reliable sealing of swirl flap ports, reducing intake leaks and stabilising idle
- • Best for: Owners of BMW M47 and M57 series cars listed in the compatibility notes
- • Not ideal for: Vehicles outside the listed BMW M47/M57 compatibility range or non-BMW engines
Six 33mm blanks arrive with matching intake gaskets and O-rings for installation. Designed as an aftermarket blanking kit compatible with a range of BMW M47 and M57 engines.
Secure intake sealing - With 33mm aluminium bungs and supplied O-rings
Each 33mm blank fits into the swirl flap port and compresses an O-ring to form a positive seal against the intake bore. The aluminium construction resists deformation under clamp pressure.
Stops vacuum leaks that cause rough idling and loss of low-end torque, restoring smoother running without manifold machining.
Broad compatibility - Thanks to fitment for M47 and M57 engine variants
Compatibility notes reference M47N/M47TU/M47TUD20 and multiple M57 variants across E46, E83, E60/E61, E87 and E90/E91 chassis. Specific model years and transmission exceptions are listed in the product notes.
Suitable for many BMW owners experiencing swirl flap failures, avoiding the need to source a matched OEM manifold.
Quicker workshop swap - With direct-fit replacement and included gaskets
O-rings and intake gaskets are supplied so the blanks replace the original inlet manifold sealing points directly. Fitment follows the same mounting faces as the original swirl flaps.
Cuts labour compared with more invasive repairs, making a practical DIY or garage job for competent technicians.
