swirl delete 32mm for BMW vehicle

thingiverse

To get rid of those annoying swirl flaps on your BMW 3 series M57, you'll want to start by opening up the hood and locating the engine compartment. Next, remove the intake manifold and take a look at the throttle body. You should see two small screws holding it in place - just remove them and gently pull the throttle body out. Now, with the throttle body removed, you can access the swirl flaps themselves. They're usually held on by a couple of small clips or screws, so just release those and carefully pull the flaps off. Be careful not to touch any of the surrounding components as you do this. Once you've got the swirl flaps out, take a look at them for any signs of wear or damage. If they're looking a bit battered, it's probably worth replacing them entirely - but if they just need a good clean, go ahead and give them a wipe down with some compressed air. After that, simply reverse the process to put everything back together again. Just remember to tighten all those screws and clips securely when you're done, so nothing comes loose on the road.
