Did you find out how much is the OEM restrictor?
Depend on the cost, I might order both and play with them to find out.

Check the price of the OEM restrictor with your MB parts dept.
At this cost (add the filter cost and the level of difficulty) I don't think it is worth the DIY. Just get the Winall unit.
For those who already have the Winall intake, it would be nice if you can do before and after dynos including a/f ratios for comparison.
Or ask Winall to provide the a/f chart. I would not buy until I see the a/f chart.
