BMW Inlet Manifold Swirl Flap Blank 33MM E46 E90 E91 E60 E61 E83 E70 E71 BMWSWIRL33MM

Product Details

Size = 33MM

As depicted above within the intake manifold of your BMW you will find these little blighters referred to as Swirl Flaps. Designed to produce a swirl of air to aid combustion when the engine is under light load. The flaps are held in place by two screws, unfortunately as the swirls move over time these screws can loosen or the spindle making their way in to your engine. This in-turn can do a number of things: jam open the valve port causing the piston to collide with the valve; enter the cylinder itself ending the life of the engine and even after leaving the engine further damage can be caused to the exhaust system.

Remove the risk of your car being written off by the swirl flaps. Remove the current swirl flaps (our product comes with full instructions showing how to do this, others don’t offer this) and install our blanking plates. Our blanking plates directly swap with your existing swirl flaps. Simply push in and screw in place. The best bit is you will notice no difference in performance from you vehicle, you may even notice an improvement if your swirl flaps have deteriorated.

Which size do I need 22mm or 33mm?

Our Swirl Flap blanks are available in 22mm and 33mm size (some refer to 33mm as 32mm they are the same thing). Unfortunately it is difficult to determine which size swirl flaps your vehicle has fitted and as such which size blanks you require. As a rule of thumb but far from guaranteed 22mm tend to be fitted on vehicles up to 2004, 2004-2006 either size can be fitted and 2006 on 33mm size. However over the years many exceptions have been found and BMW do not hold data as to which are fitted to your vehicle. We therefore advise measuring the swirl flaps in your manifold
