The guy who developed it is a retired Porsche

Every single box and most of the interia and parts is handmade. Check out the pics:

You have to send him a mail with your engine specs (zylinders/6V or 12V/max rpm) and he will taylor a box for you.

The last box I bought was about 230 Euros.

Keep EVERYTHING stock incl. the plugs.
