Someone had recently requested pics of the perforated airbox cover for the 3.2 Carrera. I took a couple of pics to show how I had done it back in 1991. I used a 1 1/2" hole saw and followed the pattern that was used by Precision Motorwerks/BRD. I figured I'd go one step further and dig up the article that may have started this modification in the first place. This is the first I had heard or saw this simple change. I also had CMW racing rebore my throttle body after reading this.

I've include pics of my cover as well as the European Car article......Hope you can read it......Enjoy.
