New swirl flaps anywhere?

adammcf · 05-14-2018, 05:23 AM

Is it possible to buy new swirl flaps anywhere? I finally put my car back together at the weekend after blanking the swirl flaps off and changing all the o-rings and gaskets on the engine etc and although the car is super quiet now and really smooth I've lost all low down power below 2000rpm which I've read about happening when the swirl flaps are removed.

Is it possible to buy new swirl flaps anywhere? I see BMW don't sell them and I couldnt find anything in a quick search online.

is the car remapped yet?

Yeah it was mapped with a standard Monster remap but I'm thinking I might need to get it on the rollers now and have a proper map setup for the car.

I had the same...under 1500rpms theres say 30% loss of torque...but over 2500rpms it revs like a mofo..for a diesel!

They come in the air inlet manifold itself which you can buy from BMW. It’s quite an expensive part c£450 brand new.
