I am selling the Mini S R53 Stealth Cold Air Intake Mod by Michael Ertel on his behalf

This is a great addition to the Tim Woodford Air Box Mod (can be found here)


With the recycling becoming more and more of a thing we should be doing I've decided that If you return the 2 templates after you have finished with them i will give you a £5 refund. These can then be used by other customers, so rather throw them away send them my way to be reused.


After so many people were asking about this after I posted this modification that I had made, I got in contact with Michael and he said that unfortunatley doesnt have the time to print these and send them out and would cost to much as he lives in Germany. I asked if he minded if i supplied them. He agreed.....

So here it is.


Michael has come up with a great design thats easy to produce and with a bit of know how he has made it reasonably easy to install with his template/templates.


If you have a 3d printer and wish to print your own you can do so here



The main part is printed in PETG and the template in PLA

Any information on installation can be found here and if you have any questions on this if you want to contact him via Facebook or Thingiverse
